thanks for the imput but the light fixtures are already done, i've got a heat lamp on the right side, theres a 100W bulb there right now but can go up to 175W and there is a uv day light that spans the rest of the lenth if need be i can upgrade the buld or and another but they'll not be moving any lower due to designe you can see in the pic there is a screen just at the top ot the door the brown strip, the lights come out right above that, the rest that is coverd is to hide the fixtures, it will not be changed, i'd have to reconstruct the entire enclosure and i'm not about to do that, when i get the rest of the stuff that will be going inside like logs and rocks and things i'll test temps and such befor actuly getting the beardie.
