Average Lumen Maintenance Characteristics
Lifetime for solid state lighting devices (LEDs) is typically defined in terms of lumen maintenance—the percentage of initial light
output remaining after a specified period of time. Lumileds projects that LUXEON products will deliver on average 70% lumen
maintenance at 50,000 hours of operation. This performance is based on independent test data, Lumileds historical data from
tests run on similar material systems, and internal LUXEON reliability testing. This projection is based on constant current 350
mA operation with junction temperature maintained at or below 90°C. Observation of design limits included in this data sheet is
required in order to achieve this projected lumen maintenance.
