Frequently asked questions about LED Lights

How long do LEDs last?

Properly used, most commercial LEDs have a lifetime of over 50,000 hours. This is because all LEDs, whether in LED light fixtures, installed as replacement bulbs, or in any other form, do not have a filament but rather rely on running electricity across a diode. The longest-lasting incandescent lighting has a lifetime of about 5,000 hours, while most are closer to 1,000 hours. Incandescent light bulbs push a great deal of electricity through the filament to get it very hot before it will emit light, and this process degrades the filament until it breaks or just stops working, at which point the light bulb is dead.


LEDs are also far more difficult to break because they are built with fewer, less delicate components. And because LED light fixtures use less electricity to generate light and create no heat, they are not likely to wear out in anywhere near as short of time. But if they get too hot or too much current is pushed through them, they will degrade. Poorly installed LED lights can begin to lose light output after 30,000 or 40,000 hours. Of course, when installed with the right power converters, this will not happen and LEDs should last their full 50,000 hour lifetime.
