how does the fluorescent light bulb work

The cost varies by manufacturer and retailer. But now the price difference has virtually been wiped out. When CFL bulbs were first introduced, they were significantly more expensive than incandescent bulbs. Hence, the bulbs do not impose as much health risk as fluorescent bulbs do. Incandescent bulbs contain tungsten which is not hazardous to the environment. When these lamps are disposed, the mercury content in them evaporates and causes air and water pollution.

But it also harms the environment due to the mercury content in it. The fluorescent light bulb is an energy saver so in that sense it is beneficial to the environment. Though there hasn't been an official study, some people suggest that incandescent bulbs impose lesser risks to the body than the fluorescent bulbs do. Along with that, a fluorescent light bulb emits lesser heat and distributes light evenly without putting a strain on the eyes. These bulbs also convert more of the electricity supplied into visible light than their popular counterparts. However, this affects the light output and is known to be used only in exceptional circumstances.įluorescent bulbs save energy and last longer, but are more expensive.

These bulbs also require optimum temperatures to work well they are known to function under capacity when switched on in lower temperatures.Īn incandescent light bulb is very sensitive to changes in voltage and hence its longevity can be doubled by adjusting the voltage supply.

They do suffer from flickering problems and shorter life if used at a place where it is frequently switched on and off. It also lasts 10 to 20 times longer than the incandescent bulb. The fluorescent light bulb is known to reduce replacement costs and is an energy saver. Fluroscent light bulbs are better than incandescent bulbs in almost every way: lifetime cost, environmental impact and energy savings.
