I ask because I am using the CFL's to light my snake enclosures. Not for uvb, but just for lighting. I am using a red light hooked up to a thermostat 24/7 so I don't want to keep switching out a daylight and a nightlight bulb. I'm glad to hear they aren't as bad anymore but would it bad for arboreal/semi-arboreal snakes that stay up in the canopy most of the time?
This is my carpet python's enclosure and he is always perched up somewhere at the top and I'm afraid being that close to the light may be bad for his eyes. I am using the reptiglo 2.0(the weakest I think? but brighter than the 5.0). I might switch to the 5.0 since the site says the 5.0 is designed for a tropical habitat with less light output.
