ABSOLUTE SERIES™ LED Module maximum temperature rating

The ABSOLUTE SERIES™ LED Modules (PN 7001.50 / 7001.65) are pre-built LED circuitboards designed to operate at DC 24 volts constant voltage.

We do not specify thermal resistance or junction temperature limits and instead use a simplified case temperature (Tc) specification.

The case temperature is defined as the surface temperature of the printed circuit board (PCB). Our recommended maximum case temperature is 185°F (85°C). In other words, as long as the PCB surface does not exceed 185 °F, we are confident in knowing that the LED emitters and components are within their thermal limits.

Our internal tests have indicated that the LED modules have similar reliability profiles at 185°F as well as a lower 130°F (55°C) case temperature point. For both temperature points, lumen maintenance at 6000 hours was 96%, and chromaticity shift (Δu'v') was less than 0.001.
