Question

How is a fluorescent light bulb different than an incandescent one?

Answer 1

In an incandescent light bulb, a hot filament gives off light and heat.  The filament is heated by an electric current passing through it, and is contained in a vacuum to prevent it from scorching.

In a fluorescent lamp, light is produced by passing an electric current through an ionizing gas that gives off light when its atoms are "excited" by the flow of electrons.  Fluorescent lamps produce much less heat than incandescent lamps, and therefore waste much less energy for the amount of light produced.

For much more information, try an internet search on "electric light," one on "fluorescent light," and one on "incandescent light."

Good luck.

Answer 2

A fluorescent light bulb has only a gas inside and the gas is in a vacuum and will conduct electrons. It glows a wee bit but it emits ultraviolet light and it would hurt our eyes. So the phosphors and mercury on the coating start to glow real bright and block the ultraviolet light..

Answer 3

the flourescent one doesnt use the same filaments and conserves the earths resources...less pollution too
