  • Source Four LED Fan Temperature Ranges

    Symptoms/Issue

    - At what temperature does the fan on the Source Four LED turn on?

    Description/Explanation of Issue

    The Source Four LED fixtures, both Series 1 and Series 2, have a fan on the back to maintain proper running temperatures. The fixture will take its running temperatures from both the LED Array and the Control Electronics. The fans can be left in Auto Mode, which allows the fixtures to vary the fan speed based on internal temperature requirements, or DMX Mode which allows control of the fan speed from a DMX console.

    However, even in DMX Mode the fixture will protect itself and turn on/speed up the fan as the temperature requires. The fan will respond to individual LED temperatures as well as Control Temperature. Please see below for a chart detailing the temperature ranges at which the fan with turn on or speed up.
