LEDSense® OPERATION, THERMAL DERATING, & LUMEN MAINTENANCE
The TRK-R16 employs TerraLUX’s patented LEDSense® Thermal Management Technology to automatically provide max-
imum light output in various fixtures and operating conditions while assuring long-term lumen maintenance. LED-
Sense® regularly measures the operating temperature and ensures compliance with a pre-programmed temperature
and drive-current profile. This profile is based on the LED manufacturer’s LM-80 data report and minimum L70/60,000
hour lumen maintenance curves. LEDSense® is always active, and will compensate for variation in thermal conditions
due to heatsinking, ambient air, module positioning, or any other variable that affects the operating temperature. The
Thermal De-rating curve below identifies the relative light output that can be expected under various thermal condi-
tions. The LEDSense® Power Curve identifies the reduction in input power over temperature. .
