I would say that all that talk about how they have to get within so many inches of the 5.0 bulb to reap the bennefits of UVB is borderline nonsense. [...]Lyneeso
Why would you say that? Even with uv bulbs the uvb/uva wavelengths are still travelling through glass, irrespective of how its treated. You cant just re-create the sun in a bulb, there will be issues associated.
(I use it about 10-18inches above).
why?
Ive been keeping/breeding various species of lizards (many of them desert dwelling agamidae)for 20 + yrs myself, personally Ive nevered bothered with artificial uv sources, excepting for hatchlings-6months, I prefer to provide natural sunlight.
This said, some species require higher more constant levels of uv radiation than others.
For example I found using using artificial Uv sources within 6-12 inches of hatchlings-6 month animals, significantly boosted their eating and activity, as opposed to none (years ago there wernt any) or uv used without concern for proximity. (early trials).
Ive been keeping lizards of all types my whole life and have NEVER noticed any real indicators that the lizard must be within 6-12 inches of the bulb.
So you've never seen/had a lizard develope MBD, and you've used artificial Uv 'your whole life', at 10-18 inches above yes? or you simply
?
Do you want to share your experience with artificial Uv sources specifically or simply tell us your an 'expert' and dont agree?
If research shows a given bulb requires to be within a given proximity, and the bulbs manufactures themselves reccomend it, why would you consider it nonsense? why would use artificial uv at all?
