OK, I sprung for the MVB so I now have full spectrum lighting coming from the basking lamp, in addition to from a florescent. I bought a 100 watt T-Rex flood and set it up the minimum 12 inches from the platform, replacing a regular Repti Spot bulb. Wow, it was expensive!
Anyway, all is well, except that the ambient air temperature is lower, I suppose because the MVB does not throw off as much heat as the old incandescent. It was about 90 under the old lamp on the platform; now it is about 80, give or take a few degrees. Is this an issue?
