I heard compact bulbs cause eye problems to chams
I think compacts have a bad rep, just because 'everybody heard it'! When compacts came out several brands did indeed cause photo blindness, and apparantly were removed from market. (somewhere here theres a well read thread about the UK photo blindness/compacts issue).
The reason was/is that The two uv wavelengths A and B were not balanced, A far higher than nessesary level of Uvb than found in previously manufactured bulbs/tubes or sunlight did the damage. More uv is NOT BETTER than a little! (this is akin to over supplimenting)
HOWEVER....Be aware that the high uvb idiocy still prevails and some linear (long tube)
types do the exact same damage because they have extra high UVB output.
These are generally Uv 0.10 tubes.
Just recently I switched a Uv 0.2 tube (Repti-glo © by exo-Terra) to a Tube called 'reptasunplus' 10.0 that had extra high UVB wavelengths.
I was thinking the screen of the cage would cut some out, plus it was a linear (long tube) so it must be ok right? Wrong!!
After three days my poor cham was clinging to his branch with his eyes clamped tightly shut and spending long periods down on the floor among the plants.
After just an hour of switching back, hes happy again and resumed normal behaviour and his color is brighter.
So just because its a tube, dosent mean its safe. Dont use 10.0 uv for anything, even desert herps, they all are excessive uvb wavelengths.
If your animal needs more uv than you provide with a uv 5.0 tube, then get it outdoors instead!
I will be buying a 5.0 Repti-glo © by Exo-terra shortly. Some names you can trust, some you cant.
