Hey, I heard that you should not put a Mercury Vapour Bulb on a thermostat at all. Just wondering why? I am guessing it has something to do with the filament in the bulb not liking thermostats turning on/off or dimming etc, thus blowing the bulbs maybe. I currently have a MVB set up to a IMIT thermostat as a temp housing for the next day or so (probe is in a position that it should never get to be turned off by the thermostat). Also wondering if you can mess about with a IMIT thermostat to never turn off without me having to muck about with electrical wires, or should I just be done with the IMIT and remove it completely? Trouble is it already wired up into the enclosure I bought. Cheers.
