Had a quick question if somebody can answer ASAP does the fan on the fixture turn on as soon as you turn the hqi light on or does it have a thermostat and turn on at a set temperature my fan is not on and just needed to know if it needs replacement just purchased used thank you.
There is no thermostat on this fixture if I recall. The fans are set to run with the timer for the MH bulbs. If the MH's are on and the fan is not, I am pretty sure it is a problem.
