Can someone please help me decide between the two options I have in mind for my UVB setup? I will be going with two single OR twin T5HO fixtures for the Zoomed T5HO Reptisun fluorescent linear bulbs. The Reptisun 5.0's should be used at 18-24" from the animal and the 10.0's should be used at 30-36" from the animal. These distances are used when there is nothing between the animal and the bulb. I simply don't know which would provide better UVB exposure and lighting. This is for a 4' Tall x 4' Deep x 8' Wide enclosure and the T5HO fixtures will be right around 4' apart from each other. The fixtures will be mounted to the ceiling inside the enclosure. I will be going with either the 22" or 34" length fixtures. This enclosure is for my Boelens python and although pythons don't require UVB exposure, I would like to provide it in the right amount. With the help of Dion at Spyder, I decided to go with a single regulated heat source for this enclosure, which is a 200w, 24" x 24" panel from Pro Products. Here are the links for the fixtures and also the concept images that are scaled. Actually, I don't know how to upload my images.
