I did already replace the 5.0 with a 10.0 uvb light. There is about 14ish inches to the bottom of the tank and about 12 or so inches diagnally from the top of his perch. I just wasn't sure if it'll be better off on top of his tank, but then it's 2 feet from the floor of the tank, and I know it loses some of its strength passing through the mesh. As for the three domes, it has a 75 watt basking light, which I assume I should upgrade with the bigger tank? The middle one is a ceramic heater, not sure the wattage my girlfriend got that one. And the other is another low power ceramic heater.Are the dome fixtures on top your basking lights? The UVB light looks like one of the ZooMed LED UVB rigs. I think those come with a T5 5.0 bulb which I'd replace with a 10.0 version or the Arcadia 12% equivalent. The LEDs are supposed to be 6400k daylight which is good. I'd probably just leave them off at night though.
As to your question about placement, it looks like it takes up quite a bit of the overhead space. The photo doesn't really show how much space is available behind it. With the 10.0 UVB light I'd make sure it's about 12-14'' above the main basking area and next to the basking lights (as close as you can do within reason). With the 5.0 that it comes with, it would be more effective a bit closer at around 6-8'', but that might be bothersome with the LEDs that close in. I like to try and keep most of the lighting at least 12'' up and well out of reach partly to prevent burns from the basking lights and partly to help provide a wider beam of light/UVB across the enclosure.
I did turn the lights off after the picture was taken because I thought they were too bright. As for the night time I did have them on last night, but I will be sure not too. Thank you for the assistance.I'm sorry but i litterally almost pulled my hair out because your NEVER supposed to have blue or red light also whats the wattage of your basking buld and what type of uvb to you use
