We are, so far, happy with the repti glo 10.0, but I am by no way recommending it for everyone. I did in fact try to get a repti sun or an arcadia 12%, but (as mentioned above) unfortunately found that they do not offer a 42" strip (they seem to skip that size), and our expensive setup is setup for that :?
Draco is doing well and is healthy (up to now), IF, however, he does show any symptoms of eye problems, lack of energy, not feeding (which we would notice for sure since he is a right greedy lil guy lol), we do certainly re-think and immediately try all we could to create an alternative.
It is a shame, because we heard (on this forum) that the repti glo 8.0 was ok to use, and so ordered one off eBay, just to receive the 10.0 and so I am assuming (since the seller never answered this question), that they no longer sell the 8.0?
Out set up is 24" top to bottom, so at his highest basking spot (which he only occasionally uses) is about 12" from the uvb strip, his usual spot, I would estimate, is about 15-18" away, and this seems to be where he prefers to bask most of the time, but for small parts of the day he does move up to the higher one and I am hoping, that this is his natural built in meter, making him go higher for his (in the wild) mid day extra uvb? I might be way off the mark, but since the rays of the sun would reach higher intensity during mid day in the desert, giving him the higher basking area should he need it, will hopefully give him the choice of how close he gets (no closer than 12") when he feels he needs it.
Anyway, like I say, I am no way recommending it, just pointing out it is working for us, up to now! I do recommend, that anyone using ANY type of uvb source, re-thinks everything the minute they notice any problems, and this forum is an amazing place to find out information!
Cheers
