When you buy an LED bulb, you expect it to last longer than older types of lighting. And for the most part, it does. But how long an LED actually lasts depends on a few factors: how it’s used, where it’s installed, and the quality of the product. So, how long do LED bulbs really last? Here’s what you need to know.
Average lifespan of an LED bulb
Most good quality LED bulbs are rated for 15,000 to 25,000 hours of use. That means if you use a bulb for around 3 hours a day, it could last anywhere from 13 to 22 years. But that’s just the average. Some higher-end models and integrated fittings can go beyond that, especially when used in ideal conditions.
Unlike older bulbs that fail suddenly, LEDs tend to fade gradually over time. You’ll notice them becoming dimmer before they eventually need replacing. Manufacturers call this “lumen depreciation”, and a bulb is usually considered “finished” when it drops below 70% of its original brightness.
What affects the life of your LED bulb?
LEDs are more efficient and reliable than halogen or incandescent bulbs, but they’re not immune to damage or wear. A few key things can shorten their life if you’re not careful.
-
Heat: LEDs don’t like overheating. Poor ventilation or using bulbs in enclosed fittings can reduce lifespan.
-
Power surges: Spikes in your electrical supply can damage the internal components.
-
Frequent switching: Turning the light on and off constantly (especially with dimmers) can cause extra wear over time.
-
Low quality fittings: Cheap, poorly made LEDs are more likely to fail early, even if the packaging says otherwise.
To get the best out of your bulbs, choose products with proper heat management, stick to trusted suppliers, and match the bulb to its intended use. LEDs used in well-ventilated spaces like open pendant fittings or wall sconces usually perform better over time than those boxed into sealed enclosures.
