CFL and LED light bulbs

Home lighting technology has come a long way from Thomas Edison’s heated filament incandescent bulbs. Today, people like you are replacing their inefficient incandescent bulbs with CFL (compact fluorescent light) and LED (light emitting diode) bulbs, and saving hundreds of dollars at the same time.

The incandescent light bulb loses as much as 90% of its energy as waste heat. New technologies have made efficient CFL and LED light bulbs competitive choices for most home lighting needs.

Compact fluorescent light bulbs use an integrated ballast to energize chemical vapors. These vapors then produce ultraviolet light. That ultraviolet light strikes the fluorescent coating inside the bulb’s glass housing, which produces visible light. CFLs have been around for decades, and can now create everything from the warm glow of your favorite reading lamp to clear, bright light perfect for your kitchen or home workshop. CFLs cost as little as $2.00, and can last for 5-8 years.

Light emitting diode bulbs are newer than CFLs, and they promise to last an extremely long time in normal usage. These bulbs create light when energized electrons pass from the negative to the positive charged layer in a semiconductor. Because they draw very little electrical current a 60 watt equivalent bulb may only use 7 watts of electricity! This makes them very inexpensive, and it also makes them suitable for use in antique lamps with ow power draws. LED bulbs can cost as much as $60 for a 60 watt equivalent, but they will last for decades – and the price is dropping every year.
