Hey, Is it ok to control temperature emitted by the Mercury vapor bulb by using a dimmer switch? I know people use dimmer switches to control the amount of heat radiated from a regular light bulb/basking bulb, but I am asking about MVBs, specifically, Rep-Pro's Self Ballastered MVB. Does it affect UV output? Wear out the bulb somehow? The climate's starting to warm up a bit and this is stumping me. I can't adjust the distance of the bulb constantly, not can I change to a new MVB everytime the weather changes. I currently have two bulbs. One MVB 160 Watt and one regular basking bulb 150 watt. The MVB shines on its favo basking spot, but the other light keeps the other end of the platform warm. Don't know if I should turn off the basking bulb, or dim it. Would that correct the temperatures overall?Because the heat from the basking spot would radiate elsewhere? Or will the MVB basking spot still be too hot? While I'm at it. Do lower Wattage MVBs emmit less UVB? Or just less heat and light and use less electricity?
