What are fluorescent lamps?

fluorescent lamps produce light by electricity to excite the steam of mercury that produces ultraviolet light. Ultraviolet light is caused by a phosphorescent coating of fluorescent lamps on fluoresces or glow with visible light. Fluorescent lamps are more and more complicated and more expensive than traditional bulbs, but are much more energy efficient and last longer and save money in the long run. Fluorescent lamps use a ballast to control the amount of electricity that flows through the lamp because they need only a small amount and self -restraints would be under uncontrolled flow.

Fluorescent lamps acquired in popularity during World War II and by 1951 were more lighting produced by fluorescent lamps than bulbs in the United States.

Until recently, fluorescent lamps have been used only in institutional and large commercial buildings. The compact fluorescent lamp (CFL), suitable for home use, was invented in the 70s and until the early 80s became commercially accessible. But when he first appeared on the market, CFL was very expensive, which is now equivalent to $ 30. Edward Hammer of General Electric in 1976 invented the spiral design of most CFL available today, but until 1995 he did not get into consumers.

Home use of fluorescent lamps in most countries is still low on energy savings. The bulbs are now very rare in eastern and southeast Asia, and Australia and Canada have accepted plans to gradually end the bulb in several years. Fluorescent lamps can take 10 to 20 times in terms of bulbs and current models produce the glow almost indistinguishable from the glow of traditional bulb.
