Types Of Lightbulbs

Types Of Lightbulbs

Since the invention of the first incandescent bulb by Thomas Edison and Joseph Swan in the 19th century, different types of lightbulbs have illuminated our homes, offices, and buildings. In the intervening two centuries, light bulbs have made great strides in terms of efficiency, light quality, density, and energy saving. Despite the fact that we all have a mental image of a light bulb, they come in a variety of shapes, sizes, voltages, and materials.

An uninspiring space can be transformed into one that is welcoming by a simple change in the lighting. A well-lit home is both visually appealing and functionally sound. It can be difficult to choose light bulbs because of the variety of characteristics, such as brightness, color, and energy efficiency. Here are some different types of lightbulbs, along with what makes them unique.

Light Emitting Diode

Because of their low power consumption and wide range of color options, light-emitting diodes (LEDs) are becoming increasingly popular. The electron flow and photon emission occur as a result of applying electricity to a negatively charged diode in an LED. The diode produces light by combining the photons.

Diodes are used to provide the desired quantity of light for an LED bulb. Due to their semiconductor nature, LEDs use less power to generate more light and are therefore more energy efficient. You can ask your Electrical and Lighting Distributor Bay Area to deliver an LED of whatever hue you choose because LEDs can emit colored light without the use of color filters.


To mimic high-noon sunlight, these lights generate white light. They are ideal for recessed lighting, pendant lighting, and under-cabinet lighting because they are both energy-efficient and dimmable. The life expectancy of this lightbulb is the shortest of the four. Because they heat up so quickly, it’s critical to keep them away from potentially combustible things. The oil from your hands can potentially cause the bulb to burst if it gets too hot, so we advise that you use gloves when changing the bulb to avoid this.

Compact Fluorescent Lamps

There are a wide variety of colors that these bulbs can produce, depending on the model you select. For the most part, they take a while to get going and warm up. Basements, great rooms, and kitchens can all benefit from these lights. Because of their lower cost and longer lifespan, they’re a better choice than incandescent lighting. You’ll want to handle these bulbs with caution because they contain mercury. They can be recycled once they’ve burned out.

Fluorescent Lamps

In comparison to incandescent bulbs, fluorescent bulbs are more sophisticated. Electric current flows between the cathodes in a fluorescent tube, causing mercury and other gasses to be excited, resulting in the emission of radiation. Radiant energy is converted into visible light by the phosphorous coating on the exterior. While providing the same quantity of light, fluorescent lamps use less energy and last longer than incandescent bulbs do. However, because of the mercury content, these are difficult to discard.

Incandescent Bulbs

The most common type of bulb is incandescent. Filament illuminates as electricity goes through them, making them glow brightly in an incandescent lightbulb. An atmosphere of either nitrogen or a vacuum surrounds the tungsten filament during the manufacturing process. The bulbs come in a variety of shapes and sizes, including GLS, globe, candies, and mushrooms. The quick surge in current, on the other hand, heats up the filament and eventually burns it out…… Only 700–1000 hours of use are possible with incandescent bulbs, which are a waste of energy. Although they have been around since the dawn of lighting, incandescent bulbs have long predominated in buildings around the world. They have only lately been supplanted by newer technologies such as LEDs, Fluorescent, and HID bulbs.

Lighting factors


The best way to gauge how much light a lamp produces is in lumens. They express the amount of light emitted directly by a source. LED bulbs, for example, may be able to produce more lumens with fewer watts than other types of bulbs. If you’re building a house, think about how much light each room will need. Lumens are used by interior designers to determine the amount of light needed in a given space. Lighting needs vary from room to room; a corridor doesn’t need to be as bright as an office, for example.


Power consumption is measured in watts, a metric commonly used to gauge electrical output. For example, your power provider will charge you based on the number of kilowatt-hours (or kilowatts) you consume in an hour. Make a note of the fixture’s maximum wattage rating before going shopping for light bulbs. When energy flows into a light bulb, it creates heat, especially in incandescent bulbs. The lower the wattage of the bulb, the safer and more efficient it will be. Overheating can damage wiring and create a fire danger if a light bulb consumes more watts than the fixture can handle. Light fixtures should not be exceeded in brightness. If an incandescent bulb’s wattage was employed as an indicator of brightness, it was considered accurate. The more watts you had, the brighter the light would be. It is no longer useful to quantify brightness with the current variety of light bulbs, which all utilize varying amounts of electricity to generate the same quantity of light.


Keep in mind the importance of color in your lighting design. Depending on the situation, it’s suitable to use different colored lights. Bulb light emits a spectrum of hues from yellow to blue when used in its plain (i.e., uncoated) form. The Kelvin [K] Color Temperature Scale is commonly used to gauge light color when purchasing lightbulbs. The scale’s physics are fascinating, but they’re of no use when it comes to purchasing lightbulbs. For each application, there are a variety of temperature ranges to choose from. Yellow light tends to be cozier and more calming, whereas blue light is crisper and more energizing.

Types Of Lightbulbs: A Conclusion

These are the main types of lightbulbs and what makes them different. When it comes to picking a lightbulb, don’t forget to take the color, watts, and lumens into consideration.
