There is no doubt about it…
The electric light bulb can easily be considered one of the greatest inventions in human history. The application of the light bulb is almost endless, but some of it’s most impactful benefits include safer living due to less fires needed for lighting, night transportation, more efficient working production, and “night life” which was made possible by this crucial breakthrough.
Those who are interested in light bulbs will find this comprehensive reference useful.
We’ll cover everything you want to know about light bulbs, from their illustrious past to the finest sorts of LEDs to use in certain scenarios.
You may pick up some useful information that you didn’t know previously.
A Brief History Lesson on the Invention of Light Bulbs
The light bulb wasn’t conceived by Thomas Edison in 1879, as we’ve been told in school, but it was a complex process that involved numerous innovators throughout the world for about fifty years. In the 17th century, the very first light sources were developed.
Sir Humphrey Davy from England then invented the first electric light in 1802. Even though Davy’s light was still not commercially viable, it was the beginning of something monumental.
This section focuses on some of the people and events that paved the way for Edison’s success.
Frederick de Moleyns: 1841
Fast forward to 1841, once Frederick de Moleyns acquired the first English patent for an incandescent with a glass bulb, after a flurry of adaptations by other innovators.
The bulb, though, was not quite right. Because of the bulb’s design flaw, it heated up far too rapidly. As a result of the stale air, the glass bulb was scorched and quickly went out of power.
Hermann Sprengel, a chemist, made a significant discovery in 1865, twenty-four years later. The filament was preserved and the blackening problem was eliminated by removing the air from within the bulbs. Even today, his mercurial vacuum pump system has his name because of its success. As the name implies, it’s called the Sprengel Pump.
Henry Woodward and Mathew Evans: 1874
Mathew Evans & Henry Woodard are introduced in the year 1874. The invention of incandescent bulbs with nanofibers by these two individuals was patent-pending in the U.S. Their light bulbs functioned great, but they weren’t attracting customers. The Evans-Woodward partnership gave up five years later and sold their invention to Edison.
Edison as well as the Muckers vs Joseph Wilson Swan: 1879–1911
It is now the year 1879. Within six weeks Thomas Alva Edison set out to develop an incandescent light bulb that would be a viable replacement for gas lighting. The “muckers,” a group of 14 guys he assembled to assist him, immediately set to work. Edison’s crew, on the other hand, was up against some stiff competition. Sir Joseph Wilson Swan, a British inventor, was also working on the incandescent bulb. He was granted a patent inside the United Kingdom on his own. At midnight on December 31, 1879, Edison and his crew exhibited their latest light bulb innovation. The year was 1880, and Swan had a functional light on display. The inventions of both Edison and Swan worked, but neither was commercially viable. Improvements to their inventions were made by both men. Edison formed the Edison Electricity Provider and secured two U.S. trademarks for his now cost-effective light bulbs. The Swan Electric Corporation was formed in 1881 after the development of Swan’s light bulbs.
After both parties accused the other of patent violation, Edison took legal action. The 1883 merger of the Edison Power Company and also the Swan Power Company was a result of Edison’s defeat. The Edison & Swan United Incandescent Light bulb Company, Ltd. was formed as a result of their union. Swan was eventually acquired by Edison, which was then known as Ediswan. Electricity was revolutionized thanks to Edison’s invention of the incandescent light bulb. The carbon filaments were replaced with tungsten in 1911 by William D. Coolidge, resulting in a brighter, longer-lasting bulb. Considering this, was Edison, as often believed, the lone inventor of the incandescent bulb? The answer is a resounding nay. However, he was instrumental in the technical and economic creation of the incandescent lamp.
Edison light bulbs have become the standard name for screw-based lights and are sometimes labeled on the box with an “E” and a number to identify the size. For example, an E12 light bulb has a 12-inch light bulb base diameter and is a propeller (Edison) light bulb.
New Approaches to Lighting
There are various new lighting settings to pick from if you prefer to stay up with the newest technical developments.
Manufacturers have invented light bulbs that can be turned on and off with just the sound of a voice.
A built-in Speaker system allows you to broadcast your music wirelessly from these LED light bulbs. There’s also music-synchronized or music-independent color-changing technology with up to 16 colors to suit any occasion or mood.
Use your smartphone to switch on the lights in your house before you come home. Or perhaps you’ve reached the climax of the film and don’t want to get up from the couch just yet? Smart light bulbs allow you to manage your illumination from a smartphone. Lights can be dimmed, turned on or even off, or scheduled to turn on.
Color Temperature of a Light Bulb: Is it relevant or not?
Only a small percentage of consumers care about the quality of their incandescent fixtures. Watts was the original unit of measurement for brightness. However, the new metric employed is lumens since energy-efficient bulbs may generate the same amount of light while using fewer watts to power them. Lumens measure the brightness of a light bulb by measuring how much light it emits. High-lumen lights produce more light.
With bulbs, lumens are not the only factor to keep in mind. Color temperature or Kelvin rating is another factor to consider when purchasing a light bulb. From 2,700K to 6,500K, Kelvin ratings can be further categorized by their color temperature designations.
The Kelvin temperature range for soft white light bulbs is between 2,700 and 3,000 degrees Fahrenheit. Warm and yellowish hues will dominate. You may use these lights to create a calming atmosphere in your bedroom or den or living area.
3,000 and 4,000 Kelvin lamps are considered warm white. A yellowish-white hue is produced when white is heated to a higher temperature. This color temperature will make your kitchen and bathroom the most relaxing place to be.
4,000 and 5,000 Kelvins are the most common range for bright white lights. Kitchens, workplaces, and other workspaces are best served by the color temperature’s dynamic feel.
When the Kelvin scale ranges from 5,000 to 6,500, it has a blue hue to it. Color temperatures like these are best used in the vanity area as well as in areas where you spend time working and reading.
What bulb to use in what room and for what specific purpose?
There are several factors to consider, such as color, form, and size when using them for different reasons.
What function is your lighting utilized for?
General / Ambient
Is your purpose to supply illumination to the whole room? Then you need to choose a bulb adequate to produce enough lighting to fill up the complete room (adding the ambiance).
Is your purpose to offer illumination to conduct particular tasks? Your purpose here would be to have a strong light, a bulb with a greater kelvin temperature will be excellent. Your usage of illumination is most probably a light, which is fantastic, as lamps normally come with the bulb. Great selections
Is your purpose to highlight or showcase an area? Your idea might be to try for low kelvins to protect the region’s objects and for a lamp that is positioned to solely showcase that specific location.
What shade do you use?
- A typical warm, homey sensation may be achieved with the use of soft white/warm white in bedrooms and living spaces.
- This color is ideal for kitchens, bathrooms, and garage areas since it provides a bright, vibrant vibe.
- It is best for bathrooms and kitchens; reading, complicated tasks, or applying makeup can all be done in daylight — it gives the greatest contrast between colors.
There are a few things you need to know when purchasing a LED light bulb, even if they appear to be identical. There are product websites on the internet or on the lightbulb box if you’re buying at a brick-and-mortar location that provides this information too.
People have been used to just turning on and off light bulbs, but some relish the ability to dim the brightness of a space to suit their mood or to do quite the opposite when desired. Some Led bulbs are dimmable, but not all of them, and those that are LEDs aren’t compatible with all dimmer switches out there.
As a result, manufacturers supply a list of dimmable with which they have tested and are thus guaranteed to work together. Unless you want to replace your dimmers, you’ll likely have to check through several different LED manufacturers to locate one that works with the ones you already have in your workplace or at home.
Color Rendering Index (CRI) is indeed a number from 0 to 100 that assesses the effectiveness of a light bulb to produce colors relative to midday sunshine. Incandescent lights are certified at 100 and several LED bulbs are generally rated between approximately 80 and 85.
This implies that unless you were to switch a conventional for an LED bulb all colors wouldn’t appear as nice, but the savings exceed this exchange off in most instances.
Nevertheless, if the contrast ratio is crucial to you, search for Light Bulbs with a CRI near 90 or better. In most situations, the visual difference between 100 CRI and 90 CRI is not perceptible by most people.
Safety and Enclosed Fixture Ratings
Ratings for all bulbs will tell you what circumstances they may be used in:
- Moisture or water should not be present in the region where the bulb is utilized.
- The bulb may be utilized in damp environments, such as restrooms, where there is a lot of moisture in the air.
- The bulb can be placed in a wet environment, but it cannot be immersed.
- Fully enclosed fixtures such as porch lights or ceiling fixtures are safe to use with this bulb.
- Non-enclosed rating bulbs may burn and reduce their lifespan if used in a closed fixture.
Because the fixture isolates the lamp from moisture, dry location bulbs may be utilized in street lights, such as gardening lights. Open-air lighting, such as eve downlights, cannot utilize a bulb unless it is damp location rated.
Even though no one can predict when a lamp will cease operating, manufacturers do give an estimate of how long it should last. Depending on how long it takes for LED bulbs to stop providing 70% of their lumen output, that rating is determined.
It is common for LED bulbs to have an estimated life span of between 15,000 and 26,000 hours. It is possible to get bulbs that can endure for up to 50,000 hours. LED light bulbs may last for many years, therefore knowing how many life hours a bulb has is important since it could explain why that bulb is more expensive than another.
Energy Star and JA8
Some LED lights may also be certified for their energy efficiency. LED bulbs can be voluntarily submitted by manufacturers for efficiency testing and are overseen by the EPA and DOE. The use of Energy Star-certified bulbs saves money on electricity bills because of the constant, long-lasting light they provide. These bulbs may also be eligible for state or municipal subsidies.
In addition, JA8 is another certification that you should consider. As of 2017, all new residential and commercial construction, repairs, and additions to existing structures in California must use JA8-certified lighting, as stipulated by Title 24 rules. Longer lifespan, dimmability, and high color rendering index (CRI) are all advantages of LED bulbs that have passed these stringent tests. Refunds for JA8 lights, like those for Energy Star-certified bulbs, may be available. As governments tend to follow California’s energy restrictions within a few years, you never know if your state may mandate the use of these bulbs.
Tips on Choosing Your Light Bulb
The ambiance and mood of the space are profoundly influenced by the sort of lighting it has. With the right lighting fixtures and bulbs, your house is illuminated in a way that is both beautiful and functional. The chemistry of lighting can help you choose the finest light bulbs that fit your style and your house.
Luminous flux and electrical power
Watts-to-lumens conversion graph for measuring light output.
The measurement of light output & energy consumption using units such as lumens and watts is critical.
A light bulb’s lumen output is measured in lumens. The brighter the light, the more lumens it has. The darker the light, the fewer lumens it has. About 1600 lumens are produced by a standard 100-watt bulb. Light bulbs use watts of electricity. Electricity costs are reduced when light bulb wattage is reduced. There is no difference in light output between incandescent bulbs and compact fluorescents (CFLs) or LEDs.
Never use more power than the light or fixture manufacturer recommends.
Part bulbs have been shaped to assist dissipate some of the heat from a single bulb, such as gu10s, which have a huge surface and thermal sink to distribute the heat.
Each has its own set of specifications for how much power it can manage. When it comes to getting the recommended amount of watts, you’ll need more conductors for a large bulb, and you’ll need fewer for a tiny bulb.
The quantity of surface area that light can illuminate is referred to as the reach of the term. Some rooms in the house are larger than others, necessitating the use of a bulb with a wider spread. The B22 is a good illustration of this, as its only function is to produce as much light as possible.
Size is a major consideration. Chandeliers, like the G9s, use several tiny lights instead of a single huge bulb to provide more light while maintaining a more elegant appearance.
Lights that can be dimmed or brightened
A bulb that can be used with today’s fixtures, such as dimmable lights, is becoming more necessary. Using this type of fixture necessitates the addition of a lamp, which will serve to both absorb heat and provide a spotlight on the desired region when adjusted.
In certain cases, the purpose of some bulbs is just to enhance the aesthetics of the room. For example, a candle-based bulb for wall lighting would work well with a high-end light fixture, creating a traditional look.
The Kelvin (K) degree scale is used to quantify light color or appearance, and it’s the distinction between soft white and daylight bulbs. Whiter or bluer light has a higher Kelvin number than yellower or darker light has a lower Kelvin number.
- 2700K to 3000K for a soft white with a yellowish cast.
- Incandescent bulbs come in this standard color—a great way to bring out the richness of dark timbers in a space.
- 3000K to 4000K (in the middle of the yellowish & white temperature spectrums)
- Ideal for use in the kitchen, office, or bathroom.
- White Light 4000K to 5000K (here between White & Blue Ranges)
- In the bathroom and kitchen with chrome and white fixtures, these bulbs like GE Reveal Fluorescent Bulbs perform well.
- Between 5000 and 6500 kelvins are considered daylight (in the blue spectrum).
- Light and easy on the eyes, these lamps are ideal for reading.
Standard incandescent and compact fluorescent light bulbs will be phased out under the Energy Conservation Act of 2007, which mandates a reduction in energy use of 25 percent. To get an energy-saving equivalent, use this chart.
Facts about each bulb from the package label.
Reading what’s on the Label
To make the most of your lighting investment, look for labels that give simple tips. The Federal Communications Commission now mandates that they appear in light bulb packaging. Facts include brightness, anticipated yearly cost, mortality rates, light appearance, energy utilized, and mercury information.
Dimmer Switch Capabilities
Dimmer switches provide you with additional control over the lighting in your home or workplace. With a simple wire, you can regulate how much light is coming into your home at any given time with the help of a light switch replacement. Not all lights can be dimmed, so it is important to keep in mind if this is something you want.
The Different Types of Light Bulbs
Whereas the light bulb may be regarded as the most important invention in our civilization, its construction timeline didn’t finish in 1911. A lot of space for development and modification remained. Even now, new and improved light bulbs are being developed. Here are some of the most common varieties of light bulbs and how they’re used.
Incandescent Energy Light Bulbs
Despite their widespread usage, traditional incandescent lamps are contentious because of their poor efficiency. Approximately 90% of the fuel they consume is wasted as heat in these bulbs. This means that only 10% of the electrical energy is converted into the light we can see. As a result, the environment is harmed by the unneeded release of greenhouse gases.
Traditional incandescent bulbs use anywhere from 25% to 80% more energy than newer, more common light bulbs. We could save enough energy to light almost 3 million U.S. homes in a year if every family in the country switched to ENERGY STAR-certified Compact Fluorescent Lamps (CFLs). It’s also the equivalent of preventing the emissions of 800,000 vehicles.
Additionally, incandescent lights typically last only one year before needing to be changed, which is far less than other types of bulbs. There is a wide choice of sizes, voltage, and lumen output to choose from. However, they may be dimmed.
Where Do Most People Use Incandescent Light Bulbs?
The low upfront cost of using incandescent lights attracts buyers, even though they are inefficient. Because of this, they are more expensive for both your wallet and the environment than other options. Incandescent bulbs should be replaced as soon as possible if you still have some in your house. In today’s society, these bulbs are most typically used for:
- In the living area, decorative lighting fixtures, and table lights
- Dining rooms should include chandeliers and candelabras as centerpieces.
- Table lamps and fluorescent fixtures in the bedroom have been replaced with more modern alternatives.
When Disposing of Incandescent Bulbs, What Should You Do?
Because they are constructed of non-toxic materials, incandescent light bulbs may be thrown away with the rest of your trash. Some regions do take them for recycling, even though many do not. Do your research on recycling possibilities before throwing anything away. Put outdated bulbs in other materials before tossing them away in case the plastic breaks.
Halogen Light Bulbs
To create an energy-efficient bulb, halogen bulbs were initially introduced in 1959, as a modification of the incandescent bulbs. Two to three times longer than a regular incandescent light bulb, these bulbs use halogen gas rather than just inert gas.
What Do Halogen Light Bulbs Typically Do?
It’s possible to get a white light that’s brighter and uses less energy with halogen lights than with incandescent ones. Despite their little stature, they can reach temperatures of up to 1,000 degrees Fahrenheit. Halogen bulbs can be used for a variety of purposes, including:
- Floodlights, both external and inside
- Headlights for automobiles
- In-ceiling lighting
- Lighting Projectors for a Track Lighting System
Halogen ovens also employ halogen lamps as a heating source. We utilize them almost entirely in theatre and media production for oblong-shaped reflector spotlights and other studio lighting setups.
What Do You Do With Halogen Bulbs?
Since the filament is held in place by a halogen gas, these bulbs are safe to use. If you can’t find a recycling center for your old halogen lamps, you may simply toss them out in the garbage like you would with incandescent bulbs. Ensure they’re protected from glass breakage by placing them in a cushioned container.
Compact Fluorescent Lights (CFLs)
In the 1930s, fluorescent lights for residential and retail use became popular. When an engineer called Edward E. Hammer twisted a light tube into spiral form in 1976, it was groundbreaking. It wasn’t until the mid-1980s that the first energy-efficient light bulb (CFL) was developed and sold.
Early CFLs were expensive, of poor quality, and too large to fit in many light fixtures. However, after much work, they have become one of the most efficient and cost-effective light bulbs on the market. For the same output, compact fluorescent lamps consume 25–35 percent less energy than regular incandescent bulbs, last up to 15 times as long (6,000–15,000 hours), and utilize 25–35 percent less space.
What Are the Best Uses for CFL Light Bulbs?
A lot of people don’t like the spiral design of these bulbs. It takes a little while for them to warm up as well. As a result, few people opt to utilize compact fluorescent light bulbs in decorative light fixtures like chandeliers. CFLs, even though they don’t often function with dimmer switches, are a popular fluorescent light in the following areas: reading and project areas.
- Long-term usage of concealed light fixtures in the home
- Kitchens and baths, for example, require plenty of natural light.
- Table and desk lighting for reading and studying.
- Floodlights that illuminate the landscape at night
Another form of fluorescent light bulb is the linear fluorescent bulb. They’re tubular and available in a variety of sizes, colors, and wattages. These bulbs are commonly used for task illumination, such as in warehouses and under cabinet lighting.
Are CFLs and other fluorescent lights safe to throw away?
A limited quantity of mercury vapor is included in CFLs and other types of fluorescent light bulbs. For safety concerns, we must properly dispose of all CFLs. Many retail and hardware establishments in your area are happy to recycle your old light bulbs. You may also inquire about the policies of your local service provider. To dispose of CFL and fluorescent bulbs, the third alternative is to use a mail-back service.
To properly clean up a damaged CFL or fluorescent light bulb, the U.s. Environmental Protection Agency Agency (EPA) provides comprehensive instruction. Keep kids and pets away from the building, open the windows, and avoid vacuuming to keep the mercury vapor out of the air.
Many have also questioned whether compact fluorescent light bulbs (CFLs) cause cancer, which is worth mentioning. The EPA says that no existing data links individual mercury exposure to cancer, even though this isn’t obvious. Certain types of mercury have been linked to cancers in rats and mice who were exposed to excessively high concentrations. As a result, the study found that exposure to inorganic mercury from the environment is unlikely to cause cancer in people.
Light-Emitting Diode (LED) Light Bulbs
In 2008, the first LED light bulbs were released to the public for home use. An LED light bulb with a 60-watt power rating was developed by Philips Lighting United States in 2011. The 40-cent bulbs had a 27-year lifetime when they were first introduced.
Over the past five years, the cost of LED lights has decreased by over 85%. Now you can get them for a fraction of the cost of your old incandescent bulbs, and they consume 80% less power. With LED lights, the wow impact is heightened because they may live up to 25 years longer than incandescent lamps.
What Is the Best Use of LED Lighting?
When it comes to light bulb applications, LED bulbs can very well meet all of your requirements. But there are specific situations where these lamps are particularly useful. Most of all, focus on dimmer-friendly areas like the dining room and bedroom, especially if you have any of these fixtures. LEDs glow brightly in the following areas:
- Particularly important in the winter months are garages and adequate illumination for their outside areas.
- Downlight and recessed lighting applications
- Fixtures for the bottom of the cabinet
- Lamps at night
Disposing of LED Bulbs
LED bulbs do not contain any hazardous substances, thus the same layout rules that apply to incandescent and halogen lamps apply. LED lights, on the other hand, are created from recyclable materials. As a result, you should be able to recycle them together with the rest of your trash. If you’re not sure if your recycling service accepts them, give them a call first. The LED light bulb disposal choices may also be found online.
These light bulbs save a significant amount of energy, have a long lifespan, and emit a high-quality, bright light. For artificial lighting, street lamps, and spotlights in sports facilities and other areas, they’re excellent.
Tube Fluorescent Lamps
When compared to incandescent bulbs, they are more expensive to purchase. On the other hand, due to their extended useful lives, they usually pay for themselves during their use. In terms of brightness, you can’t turn them down. They may start flickering when they need to be changed.
Candlestick-like chandeliers and lamps can benefit from these lights. It’s because of the design of these bulbs that they offer a warm light source and are excellent for accent lighting. It’s crucial to think about whether or not you’ll need to close the curtains when you buy the bulbs. Your lighting will be much more sophisticated because of the unique form and layout.
Despite its lack of ambiance, fluorescent lighting is one of the most effective. Fluoro bulbs or a neon tube in your beloved lamp work just as well as these twisted light bulbs. They’re a powerful and dependable light source that’ll keep your desk well-lit so you have good visibility. They can’t be utilized in every application because of their distinctive design, but they operate flawlessly in the proper fluorescent bulbs.
Home and business owners alike frequently employ these powerful lights under the spotlight. You may use them to liven up your workspace or to add a decorative touch to your home’s interior or exterior lighting fixtures.
If you don’t want to worry about flickering or inadvertent dimming, these lights are for you. Offices, retail establishments, and educational institutions most frequently employ them, however, they may also be found in kitchens.
This type of bulb is ideal if you need a lot of light but don’t want to spend as much money as standard high-power bulbs. They’re great for illuminating a business or a barn as well as the outdoors.
These bulbs are excellent choices for desk lamps, under-cabinet lights, and general task illumination. There are a variety of lumen outputs and lifespans to choose from.
Circular Fluorescent Lamps
Fluorescent light is emitted in even a circular pattern by these bulbs.
Both high and low-pressure bulbs are available. Reddish yellow light emanates from high-pressure sodium bulbs, whereas white light from low-pressure sodium bulbs is more even in hue. This bulb’s light comes from sodium in such an excited state.
These bulbs’ silver surfaces help focus light on a particular area. Because they are made to project lighting in a single direction, they are the perfect bulbs to use when installing spotlights in your house.
LED Strip Lights
LED technology not only saves you money but also provides you with a lot of direct sunlight for your job. They may be employed in a variety of settings, including parking garages, garden stores, and even loading docks, due to the acrylic lens.
Types of Light Bulb Bases
Lanterns, flashlights, and ornamental optical fiber lights benefit greatly from these little bulbs, which have a 10 mm base. Even though bulb life varies, you can expect them to last for roughly 1,000 hours on average.
E11 Mini Candelabra
This is a smaller variant of the candelabra screw base. This one’s name pretty much tells you all you need to know about it (see candelabra below).
These light bulbs have a size of 12 mm, which makes them smaller. They’re most commonly seen in nightlights, but you may also find them in bathroom mirror lights or chandeliers.
This base may be used with a variety of light bulbs, however, it is not as widely used as the E26 base. If you can’t locate the bulb you need in a local store, you have two options: buy it online or buy an adaptor so you can use another bulb.
Most often encountered on smaller bulbs are light bulbs with this base. You’ll have to look hard to locate them because they’re hard to come by. Appliance bulbs and desk lights are two examples of typical bulbs that employ this base.
HID, CCFL, halogen, CCFL, and halogen light bulbs all utilize this type of light bulb socket. There are a lot of light bulbs on the market that feature this type of base.
These bulbs may be utilized in most situations, despite being somewhat bigger than the standard E26 medium base. E27 and E26 bulb bases are almost identical.
For the vast majority of home users, and E39 CPU base will never be necessary. These are frequently found in large, high-output lamps, such as floodlights and street lighting.
Large outdoor lamps and spotlights commonly make use of these base types. These bases. You’ll be limited in how you can utilize them because they’re significantly larger than other lightbulb bases. To utilize this type of bulb, most users will need to purchase an adaptor.
EX39 Extended Mogul
The bases of these bulbs are 39 to 40 millimeters thick.
Light Bulb Sizes
You may discover hundreds of various light bulb shapes in the catalogs of bulb suppliers or on their websites. Just how many are required?
There are a variety of lighting circumstances that necessitate a variety of lighting styles. A street light’s function is distinct from that of an auditorium light. It is impossible to illuminate a kitchen with automobile lights. We have several different light bulb types and patterns because the purpose dictates how much and what kind of light we use.
It is the form of a table lamp that controls whether the light is focussed or spread out at an arc or utilized for ornamental purposes. The brightness and power consumption of a light bulb are directly related to its size. A smaller bulb will often have less power and brightness than a larger one if they are of the same design but have different diameters.
As a result, we’ll now go through some of the most prevalent bulb sizes and types. We’ll start with a look at the various shapes of light bulbs before moving on to some of the more common sizes. The chart of light bulb shapes and sizes will likewise be an effort.
The A Group: A15, A19, A21, and A25
Ceiling fan: 19 bullion LED filament bulbs, A19 LED pyrotechnics bulbs in strand lights, and bedside lamps.
When it comes to domestic illumination, normal (A) bulbs are all the most often used and thought of. Lighting uses for these bulbs range from ceiling lights to lamps and vanity lights to kitchen lighting to porch light fixtures and more.
The numbers in each code indicate the bulb’s diameter in one 8th per inch.
- 1-7/8″ is the diameter of an A15 bulb.
- 19 divide by 8 = 2-3/8′′ in diameter for an A19 light bulb
- 2-5/8′′ is the diameter of an A21 bulb.
- A25 bulb has a diameter of 3-1/8′′.
Most common base types:
- Screw base E26/E27
The G group
There are G fourteen LED bulbs in the ceiling light fixtures and G30 LED bulbs for the bathroom sink, as well as G16 gold-tinted, LED fiber bulbs in the ceiling light fixtures, which are all LED bulbs.
There are many different sizes and shapes of globe (G) bulbs. For example, entryway lights, and decorative fixtures can all be employed in the home. Bathrooms and cosmetic vanities are the most popular places to find the G30 bulb.
Numbers in each code might relate to the diameter of the bulb in equal pieces of an ounce or millimeters, depending on the bulb.
- The G11 bulb has a diameter of 1-3/8′′.
- The G14 bulb has a diameter of 1-3/4′′.
- 16/8 = 2′′ in diameter for G16/G50
- G60: 60 mm = 2-3/8 inch diameter
- G25/G80: a diameter of 80 millimeters (3-9/64′′)
- For example, G30: 30/8 = 3 3/4′′ in diameter.
Most common base types:
- E12 candelabra Evaluations of performance big screw base
The C & B groups:
It is common to refer to these lights as “candle bulbs” because of the form of their filaments. These bulbs have a cone-shaped design. Conical angled (CA) bulbs have a bent apex but otherwise resemble cone-shaped bulbs. There are a lot of similarities between blunt-tip (B) and C-type bulbs, however, they have a more torpedo or bullet form. Hanging lights and other types of home accent lighting can benefit from the usage of these bulbs. They can also be used to light up holiday light strings and other types of home décor.
The numbers in each code indicate the bulb’s diameter by one-eighth of an inch.
- B10 light bulb: 10/8″ = 1-1/4″
- The diameter of a CA10 bulb is 1-1/4 inches.
- diameter of a 7/8-inch C7 light bulb
- The diameter of a C9 bulb is 9/8′′ or about 1-1/8 inches.
- C15 light bulb: 15/8″ = 1-7/8″ in diameter
Very common base types:
- Candelabras of E12
- Medium-sized screws
The BR group
Bumps in the reflector are called BR. Light is traditionally gathered and dispersed away from an ordinary BR bulb by a reflector material on the interior of the bulb. Light emitting diodes (LED) do not need reflectors. This type of bulb has a frosted, transparent, or patterned bunker lens that refracts light and gradually fades into areas that are not lit. In addition, BR lights generate fewer shadows than PAR lamps. Track lights, basement lights, show lights, and can lights all employ these bulbs, which are slightly longer and protrude from light fixtures.
These bulbs are sometimes mistaken for R20 bulbs, however, they have the same properties as other BR bulbs. The reflector is what the R is for.
The numbers in each code indicate the bulb’s diameter by one-eighth of an inch.
- 20/8 = 2-1/2′′ diameter BR20/R20 light bulb
- The diameter of a BR30 bulb is 3-3/4 inches or 30/8 of an inch.
- A BR40 bulb has a diameter of 40/8 inches, which equates to 5 inches.
Most common base type:
- E26/E27 medium screw base
The PAR group
PAR is an acronym for parabolic aluminized reflectors. Light is directed around the front of the PAR bulb using a U-shaped reflector in typical incandescent PAR lights to increase brightness. When using an LED PAR bulb, it is possible to get the hard-edged illumination (less gradual fading than BR lights) that is common in incandescent PAR lamps without a reflector. With a smaller diameter than traditional BR bulbs, these lights are typically installed flush to the ceiling or fixture, reducing the glare they produce. For outdoor emergency lights, spotlights, and floodlights as well as indoor track lights and recessed lights, can light, and can lights may be found in these types of fixtures.
As a result, PAR36 bulbs are also known as aluminized reflector bulbs (AR111). Unlike other PAR lights, these bulbs feature a relatively low-profile body. These bulbs’ interiors are made up of faceted reflectors or are coated with a reflective substance. Reflectors aren’t necessary for LED bulbs, yet many still use them. They produce concentrated, hard-edged illumination in a spot or deluge beam pattern, just like conventional PAR bulbs. They are ideal for exterior and garden lighting applications such as architectural lights, driveway and path lighting, and gazebo lighting with weatherproof housings, as well as paver lights with weatherproof housings.

Frequently Asked Questions About Light Bulbs
When it comes to light bulbs, what do you think are the best?
LED light bulbs are now the most energy-efficient bulbs on the market, and they’re also the most effective. LED bulbs have a life expectancy of 25,000 hours or more, compared to 1,000-2,000 hours for incandescent and halogen lights, and 10,000 hours for CFLs, making them far superior to the competition. This long life saves a lot of money on bulb replacements, but it also reduces the number of materials wasted in the process.
They’re also wonderful for another reason:
- It is possible to adjust the brightness of these brilliant lights.
- Durability, stress resistance, and lack of brittleness are all hallmarks of LED bulbs.
- There is no mercury vapor or other hazardous substances in LEDs, unlike its main rival, CFLs.
- It’s amazing how well LED lights intended for outdoor usage function in cold, damp conditions.
- To put it another way, these bulbs don’t produce any heat, which means they don’t compete with your air conditioner.
What is the lifespan of an incandescent bulb?
The average lifespan of an incandescent bulb is between 750 and 2,000 hours, however, this is based on laboratory circumstances, not real-world ones. The filaments of a light bulb burn out over time, and the bulb it’ll no longer function. Heat, blackouts, electrical shocks, and the number of times an incandescent lamp bulb is switched on and off are just a few of the things that shorten its lifespan. In the end, though, filament quality is the most crucial consideration. An incandescent bulb with a weak filament will not survive as long as one with a thicker, more expensive filament.
The average lifespan of an LED bulb is 50,000 hours.
LED bulbs may last up to 50,000 hours under moderate usage. A typical LED bulb may last up to 17 years if it is used eight hours a day, which is over 50 times higher than its incandescent equivalent. It may last up to 11 decades when used for eight hours a day. When compared to incandescent lights, LEDs utilize substantially less energy, making them significantly less expensive to run. Additionally, they create less heat than incandescents, allowing them to be employed in a wide range of applications. Infrared or violet light is not generated by these materials. They are also mercury-free. However, the quality varies greatly, thus an expensive bulb will live longer than one that is less expensive for uses up to 100 watts in power consumption.
Is it possible to recycle light bulbs?
Because they are too old to be recycled, incandescent light bulbs are not an option. To properly dispose of energy-efficient light bulbs, you should take them to a recycling facility instead of throwing them out. Light bulbs may be recycled at some retailers.
Because LEDs contain no hazardous materials, they may be thrown away in the garbage. However, because they are constructed of recyclable materials, you can recycle your LED bulbs in a facility that specializes in recycling consumer electronics.
Because they don’t contain any dangerous elements, halogen lamps may be thrown away in your regular trash. Even though they may be recycled, a certain procedure is required, but not all recycling plants accept them.
A recycling site that accepts CFL and fluorescent bulbs should be used to dispose of them.
What happens to light bulbs when they are at the end of their life?
There is no expiry date for incandescent bulbs. They should operate as far as the string is intact. If they’re still intact, compact fluorescent light bulbs (CFLs) have no shelf life. A hazardous waste disposal procedure is required for CFL bulbs since they contain mercury, which has been linked to health issues. There is no expiration date for LED bulbs, so long as they are in good condition, they will continue to perform.
Any type of light bulb should be kept in a cool, dry location away from children and pets. Maintaining the bulbs’ internal structure is the most important factor in ensuring their long-term viability.

Mercury is found in what sort of light bulbs?
As with CFLs, metal or ceramic halide bulbs (e.g. mercury vapor or mercury halide), and neon and high-pressure sodium bulbs, mercury is found in fluorescent bulbs.
What causes the buzzing sound that certain light bulbs make? What are the most common varieties of this?
In the case of light bulbs, the buzzing is generated by a break in the electrical current. There’s a buzzing sound as a result of the bulb filament vibrating. They are most susceptible to buzzing since they have a filament, which is why they’re the most common. This should be solved by replacing an illuminating bulb with a bulb with no filament.
