Be sure the red and blue wire face the end with red and blue wires, and the black and white wires face the other end. If you opt for the cutting method, cut the wires so they overlap the fixture wires by about 6 inches (15 cm) (150 mm). WebFluorescent lamps and tubes are an energy-efficient alternative to incandescent lamps for the following reasons: Three to four times more energy-efficient. Cost less to use. Reduce greenhouse gas emissions and other pollution from energy production. Last up to ten times longer than standard incandescent light bulbs.

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to … See more Physical discoveries The fluorescence of certain rocks and other substances had been observed for hundreds of years before its nature was understood.
