I see 3 domes is one of the domes a UVB? If so they are not good --- the best UVB's are long tube fixtures like a Arcadia Pro T 5 w/ a 12% bulb 24 watt --- found at Pet Smart - another is a Zoo Med 24" fixture w/ a Reptisun 10.0 T 5 or a Sunblaster Nano Tech w/ the Reptisun 10.0 T 5 bulb --- it would be best to have it place directly over the basking decor unobstructed 12-15 inches
