The lifespan of LED lighting products is defined differently than other light sources, such as incandescent or compact fluorescent lamps (CFLs). LEDs usually don't "burn out" or fail. Instead, they experience "lumen decay," where the LED's brightness slowly dims over time. Unlike incandescent bulbs, the "lifetime" of LEDs is based on a prediction of when light output will decrease by 30%.

    LEDs are integrated into light bulbs and lamps for general lighting applications. For example, LED battery holiday lights. Some LED light bulb solutions may be physically similar to familiar light bulbs and better match the look of traditional light bulbs. Some LED luminaires may have built-in LEDs as a permanent light source. There are also hybrid approaches, where non-traditional "bulbs" or replaceable light source formats are used and designed specifically for unique fixtures. LEDs offer a huge opportunity for innovation in lighting form factors and are suitable for a wider range of applications than traditional lighting technologies.

    LEDs use a heat sink to absorb the heat generated by the LED and dissipate it to the surrounding environment. This prevents the LEDs from overheating and burning out. Thermal management is often the most important factor in the successful functioning of an LED over its life cycle. The higher the temperature at which the LED operates, the faster the light decays and the shorter the lifespan.

    LED products use a variety of unique heat sink designs and configurations to manage heat. Today, advances in materials allow manufacturers to design LED bulbs that match the shape and size of traditional incandescent bulbs. Regardless of heatsink design, all ENERGY STAR awarded LED products are tested to ensure they properly manage heat to properly maintain light output at the end of their rated life.
