Lifetime for solid-state devices (LEDs) is typically defined in terms of lumen maintenance - the percentage of
initial light output remaining after a specified period of time.
The Warm White (NT-42D1-0425) and Daylight White (NT-42D0-0426) will deliver 70% lumen maintenance at
50,000 hours of operation at a forward current of 700mA. This projection is based on constant current operation
with junction temperature maintained at or below 120oC. The RGB (NT-43F0-0424) will deliver, 70% lumen
maintenance at 50,000 hours of operation at a forward current of 350mA. This projection is based on constant
current operation with junction temperature maintained at or below 120oC.
This performance is based on independent test data. Lamina’s historical data from tests run on similar material
systems, and internal reliability testing. Observation of design limits included in this data sheet is required in
order to achieve this project lumen maintenance.
