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.
