Thanks for all of the replies.
I have a neonate guyana rtb and 2 ball pythons in one rack. The other rack has a 50/50 cali king and a brazilian rainbow boa.
The idea was not to blind them but position the lights in the back, behind the hides so inside the hide remains very dark.
Your probably right and most LED's even the less bright ones are still pretty bright. I've been considering white neon tube but even they are pretty darn bright. The fact that I would have to drill holes in my rack for wiring.... I think i'll just see how it goes with out the lights first.
