it's good that you have all that lighting. i used to use like three bulbs for my stuff needing uvb, but i recently switched to t-rex floods. they produce a ton of heat, i think it's like 100F from 6 in away, and they have a ton of uvb/uva. since then all my stuff has been eating so much more and been a lot mroe active. they have them at zoomed.com i think. you only need to replace them every year, so thats a bonus.
