- Usage patterns: The way you use your LED bulbs can also impact their lifespan. Turning them on and off frequently can reduce their lifespan, as can using them in applications where they are subject to vibration or physical stress.
What Affects the Lifespan of LED Bulbs?
While LED bulbs are designed to last a long time, their lifespan can be affected by various factors. Understanding these factors can help you get the most out of your LED bulbs and ensure they last as long as possible.
Lumen Depreciation
Lumen depreciation is a natural process that occurs in all light sources, including LED bulbs. Over time, the amount of light produced by the bulb will decrease, eventually reaching a point where it is no longer considered useful. This process is measured in lumens per watt (lm/W) and is typically expressed as a percentage of the bulb’s initial lumen output.
Color Shift
Color shift is another factor that can affect the lifespan of LED bulbs. As the bulb ages, the color of the light it produces can shift, becoming warmer or cooler. This can be a problem in applications where color consistency is critical, such as in retail or hospitality environments.
How Long Do LED Bulbs Really Last?
While LED bulbs are designed to last a long time, their actual lifespan can vary depending on the factors mentioned earlier. In general, you can expect LED bulbs to last:
- 15,000 to 25,000 hours in residential applications
