Expected LED Lifespan

LEDs gradually decline in brightness over time, mostly because of heat. Packaged in clusters, LEDs exhibit higher operating temperatures than in ideal, single LED conditions. For this reason, using clustered LEDs at their fullest intensity significantly reduces the LEDs’ lifespan. Under normal conditions, this lifespan can be 40,000 to 50,000 hours. If extending this lifespan is vital, lower the operational temperature by improving the product’s ventilation and reducing the ambient temperature to an optimal operating temperature. In addition, limiting the overall projection intensity may also help to extend the LEDs’ lifespan.
