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-54D1-0486), Daylight White (NT-54D0-0487), and True Color (NT-54D2-0509) will deliver
70% lumen maintenance at 50,000 hours of operation at a forward current of 5000mA. 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.

Typical Beam Pattern - Lamina’s
TitanTurbo LED light engines project
a 108º - 132º (2θ,1/2, 50% of peak
value) Lambertian radiation pattern.
Narrower beam distributions can be
produced by use of selected popular
LED optics. Please contact Lamina
Application Engineering for support
with your optical needs.
