it emits more powerful light
incandescents work from heat generated by electrical resistance. fluorescents stimulate the fl gas directly, by passing a current through the gas. no wasted heat.
You get more light from less wattage (power)
it uses less energy amd produces less useless low quality heat. those are the main 2 reasons really. 2 pretty good reasons though.
Lower voltage, so it uses less electricity for the same amount of light.
It is fired by a low voltage ballast. It charges the gas in the tubes. It is far more energy efficient than incandescent bulbs.
Fluorescent uses ionized gas under pressure with very little resistance to electrical flow of current.Incandescent uses high resistance in a wire to slow down the electricity until it glows from the friction of the electricity going through it.Incandescent puts out light,but also lots of heat and light is not evenly distributed.At least half of the electricity is lost to heat from the high resistance or friction through the filament.Thomas Edison invented both trying to improve his products,as the technology became available.
