Why LED bulbs? Because ...

They are Long lasting: LED bulbs last up to 10 times longer than compact fluorescents and far longer than typical incandescent bulbs.

Durable: LEDs do not have a filament, so they are not damaged in circumstances when a regular incandescent bulb would be broken. They are solid, so LED bulbs hold up well to jarring and bumping.

Cool: these bulbs do not cause heat build-up. They produce 3.4 btus/ hour, against 85 for incandescent bulbs, which get hot and contribute to heat build-up in a room. LEDs cause no heat build-up, thus reducing air conditioning costs of a room.

Mercury free: no mercury is used in manufacturing LEDs. More efficient: LED light bulbs use only 2-17 watts of electricity (1/3rd to 1/30th of incandescent or CFL). LED bulbs used in fixtures save electricity, remain cool and save money on replacement costs since LED bulbs last so long.

Small LED flashlight bulbs extend battery life 10 to 15 times longer than incandescent bulbs.

Cost effective: although LEDs are expensive to buy but this is recouped over time and in battery savings.

LED bulbs were first used commercially, where maintenance and replacement costs are expensive. But cost of new LED bulbs has gone down well in the last few years and continues to go down. Today, there are many new LED light bulbs for use in homes as their cost keeps decreasing.

Light for remote areas and portable generators -Because of low power requirements, use of LEDs with solar panels is more practical and less expensive than running them on electric lines or generators.

LED bulbs are also ideal for using with small generators which are used in many homes for backup power.
