Compact florescent light glass

 Fluorescent lamp is a gas-discharge lamp that uses electricity to excite mercury vapor in argon or neon

gas, resulting in plasma that produces short-wave ultraviolet light. This light then causes a phosphor to

fluoresce, producing visible light.

Fluorescent tubes are found in various sizes and types, typically four and eight-foot long lamps with

varying diameters. They require separate ballasts independent of the bulb. Most times they are bulky

which seems to be cause of concern for most designers. They have different ends, on the pins, at either

end of the long tube, so they cannot be used in the wrong fixtures.

As the name suggests Compact Fluorescent bulbs are generally smaller in size than the regular

fluorescent lamps, they are made in special shapes to fit in standard household light sockets, like table

lamps and ceiling fixtures.
