How long do LED bulbs really last? LED bulbs can go for an incredible 50,000 hours. That’s nearly six years non-stop use and over eleven years in the more likely situation of being used for 12 hours each day. Compare that to your old bulbs where you feel like you are constantly up and down replacing them.

Incandescent light bulbs, the traditional kind that are being phased out, only last for 1,000 hours.

Compact fluorescent lighting has a lifespan of 10,000 hours.

So LEDs last 50 times longer than incandescent light bulbs – as well as being much more efficient in other ways. And five times longer than CFLs.

An incandescent bulb would burn out after being left on for about 41 days. That’s not even a month and a half. But the LED bulb would still be going close to six years.

How do LED bulbs last so long?

What’s so different about LED bulbs that lets them last so long? There are a few features that contribute to LEDs being so much longer lasting.

One of the ways LED bulbs are so much more energy efficient than traditional light bulbs is that almost all of their energy goes to making light, not heat. Old fashioned incandescent bulbs need to heat up the filament to get it glowing and producing light. That heat damages the bulb over time and leads to its own demise. LEDs don’t have that heat so they don’t destroy themselves in the same way.

The metal filament in the traditional bulb is the weak point. Being constantly switched on and off takes its toll and dealing with the high voltages being passed through it will, sooner rather than later, cause the filament to break, and the bulb burn out. This is a completely different model to LEDs, which have no vulnerable filament.
