How long do LED last?

Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years.

How was the first light bulb powered?

By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. Still, the lamp only burned for a few short hours.

Which lights last the longest?

LEDs usually have the longest lifespan, often lasting over a decade. Mostly, they are several times better than incandescent bulbs and most fluorescent bulbs.

Can you make a light bulb that lasts forever?

Nothing will last forever. There are a few bulbs that are still working after 100 years. But they are so dim that they are useless for giving much light. You can make any incandescent bulb last for a really long time by running it at 75% of rated voltage.
