Thanks Eric, that was my understanding but hey, I am still new to this. It seems like the black bulb hardly puts out any light but then again, I switched the plastic wrap to aluminum foil for the heat lamp "installation" so that is blocking quite a bit of ambient light from the bulb. I followed a guide that I found either on this forum or another one I was reading, but it suggested plexiglass with a round cut out for the lamp (about an inch around from the rim) and three smaller round holes on the opposite end of the lid to help pull in fresh air as the warmed air circulates. Not sure how most people orient the bulb and how much foil they use.

What is the proper placement for the heat lamp. Right now I have the UTH and hot hide on the far left side of the tank, and the cool hide, water dish, and night bulb on the far right. Is this correct or is it better to place the heat bulb in the middle of the lid?
