I do not trust the specs that they give. I have a solarmeter and I run a T5 quad fixture with single reflector for all four bulbs. I have tested a zoomed 10.0, Arcadia 6%, and an Arcadia 12%.
With the zoomed 10.0 At 10-12 inches I was in no way getting a 3UVI level like they say in the post
@Ruthless put up for you. In fact by 12 inch down from the bulb I was getting a .7 UVI. They do not give you specifics like if these are levels through screen or not. The other thing I do not like about the bulb you want to use. Is it focuses the UVB in one area.
Chameleon keepers very rarely use these bulbs and only when they have a solarmeter. T5HO fixtures with the linear bulb is what is recommended to have a healthy chameleon.
