ELS Lumen Maintenance Permformance
Lumen maintenance for ELS solid-state lighting LEDs are typically defined in terms of the percentage of initial light output
remaining after a specified period of time. We project that our LEDs will deliver, on average, 70% lumen maintenance at
50,000 hours of operation at a forward current of up to 700 mA. This projection is based on constant operation with a junction temperature maintained at or below 135o C. This performance is based on independent test data and internal
reliability testing.
