While fluorescent (CFL) bulbs generate light by sending an
electrical discharge through an ionized gas, incandescent
bulbs emit light by heating
the filament present in the bulb.
In this
video I will going to show you different between Fluorescent (CFL) Bulbs and
Incandescent Bulbs.
When CFL
bulbs were first introduced in the 1970s, they were expected to spell the end
of the traditional incandescent light bulb. After all, they are much more
energy efficient. Indeed, CFL bulbs have risen to promise in the last two
decades. But owing to their higher cost, taking longer to achieve full
brightness and the environmental concerns over bulbs that contain mercury, CFL
bulbs have not yet made incandescent light bulbs obsolete.
Fluorescent light bulbs are better than incandescent bulbs in
almost every way: lifetime cost, environmental impact and energy savings.
The fluorescent light bulb is known to reduce
replacement costs and is an energy saver. It also lasts 10 to 20 times longer
than the incandescent bulb. They do suffer from flickering problems and shorter
life if used at a place where it is frequently switched on and off. These bulbs
also require optimum temperatures to work well, they are known to function under capacity when
switched on in lower temperatures.
An incandescent light bulb is very sensitive to changes in voltage
and hence its longevity can be doubled by adjusting the voltage supply.
However, this affects the light output and is known to be used only in
exceptional circumstances.
Fluorescent bulbs save energy and last longer, but are more
expensive. These bulbs also convert more of the electricity supplied into visible light than their popular counterparts.
Along with that, a fluorescent light bulb emits lesser heat and distributes
light evenly without putting a strain on the eyes.
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. The fluorescent light bulb is an
energy saver so in that sense it is beneficial to the environment. But it also
harms the environment due to the mercury content in it. When these lamps are
disposed, the mercury content in them evaporates and causes air and water
pollution.
Incandescent bulbs contain
tungsten which is not hazardous to the environment. Hence, the bulbs do not
impose as much health risk as fluorescent bulbs do.
