What Is An Compact Fluorescent Light Bulb

Unlike incandescent bulbs which use a filament compact fluorescent light bulbs give off light when a mixture of three phosphors are exposed to ultraviolet light from mercury atoms.

What is an compact fluorescent light bulb.

What if one breaks. Cfl stands for compact fluorescent light bulbs. Cfl bulbs are another type of energy efficient bulb much like the led. They last 10 times longer and utilize about 1 3 of the energy of typical incandescent bulbs.

They use only a fifth of the electricity in other words they are 400 more efficient. Some types fit into light fixtures designed for incandescent bulbs. A compact fluorescent lamp cfl also called compact fluorescent light energy saving light and compact fluorescent tube is a fluorescent lamp designed to replace an incandescent light bulb. This generates invisible ultraviolet light that excites a fl uorescent coating called phosphor on the inside of the tube which then emits visible light.

How do compact fluorescent light bulbs work. Compact fluorescent lamps cfls are designed to mimic the light produced by incandescent lamps and are roughly the same size. Manufacturers had already started producing linear fluorescents but the linear tubes did not fit into the same socket as incandescent light bulbs. Modern cfls typically last at least six times as long and use at most a quarter of the power of an equivalent incandescent bulb.

After i bought a few compact fluorescent light cfl bulbs i heard they contain mercury. In a cfl an electric current is driven through a glass tube containing argon and a small amount of mercury vapor. These should be avoided unless being used in rooms where there is likely to be a very low level of use. Compact fluorescent lightbulbs are much more efficient because they don t produce so much waste heat.

There are two major types of compact fluorescent lamp screw in and plug in. Cfl bulbs or compact fluorescent light bulbs are very similar to the overhead fluorescent tubes you re used to seeing overhead in many commercial spaces. How dangerous are these bulbs. Cfls are known as compact uorescent lights or compact uorescent light bulbs.

The compact fluorescent light bulb or lamp is a type of fluorescent lamp generally designed as a replacement for incandescent or halogen lamps. Around the world governments have passed measures to phase out incandescent light bulbs in favor of the more energy efficient cfls. Compact fluorescent lamps cfl bulbs first emerged on the lighting market as a more energy efficient alternative to the incandescent light bulb. They cost much more at the outset than traditional bulbs but are estimated to save about 30 u s.
