I am currently using a ZooMed Powersun 100 watt MVB, however, the temps in my closed chamber are getting to high using this bulb (103 deg directly under the light, 90 deg on the cool side, and 92 deg is the ambient temp). I did a little bit of research and found out that a company called Mega-Ray makes a 70 watt MVB (I have attached a pic). The idea is to go with a lower wattage MVB to bring the ambient temperature down in the chamber. All of the reviews I have read have been very good. I am just curious if anyone has had an experience with this bulb? Because before now, I did not think they made any lower wattage bulbs than 100 W. Any feedback would be greatly appreciated. Thanks!
