A light-emitting diode (LED) is a semiconductor device (LED chip) that emits visible light when an electric current passes through it - essentially it converts eletricity into light. When one or more LED's are combined with an electrical driver and placed in a housing unit, you have a complete LED system. Long-lasting :
LED bulbs last up to 10 times longer than compact fluorescents, and far longe
r than typical incandescents. Durability:
Since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. Because they are solid, LED bulbs hold up well to jarring, bumping, shock and vibration. Additionally, they have excellent cold weather performance. Cool:
LED light bulbs do not cause heat build-up; LEDs produce 3.4 btu's/hour, compared to 85 for incandescent bulbs. Because common incandescent light bulbs get hot, they contribute to heat build-up in a room. LED light bulbs prevent this heat build-up, thereby helping to reduce air conditioning costs in the home. Mercury-free:
No mercury is used in the manufacturing of LED light bulbs. Efficient:
LED light bulbs use only 2-17 watts of electricity (1/3rd to 1/30th of Incandescent or CFL). LED light bulbs used in fixtures inside the home save electricity, remain cool and save money on replacement costs since LED light bulbs last so long. Small LED flashlight bulbs will extend battery life 10 to 15 times longer than with incandescent bulbs. Cost-effective:
Although LED light bulbs are initially expensive, the cost is recovered over time and in battery savings.
