Are they going through mesh or are they IN the enclosure?
Also, if they are in the enclosure you really only need 1 UVB light. (Reptiles go in and out of the UVB lights all day so if they have no where to get out of the UVB, it could be a bad thing).
If you want more light. Go with the 10.0 and a 2.0. 2.0's are basically just brighter light, with no UVB basically (So little if any it won't matter)
