The other thing that would be interesting, which is one of the reasons Halides are so widely used in the reef aquarium scene is their intensity and ability to penetrate greater depths in large volumes of water. This translated to reptiles, could mean that you would get active UVB reading throughout your entire enclosure, not just 8-10 inches from the bulb. The next time i am at the shop (i work at a pet store that specializes in reef aquaria, and reptiles) i will test my UVB meter on one of the halide fixtures on our show tanks at different depths and see what the results are. Of course, just with reef lighting I imagine that the UVB production would vary from bulb to bulb, especially with all the different available color temps (degrees of Kelvin), as well as from ballast to ballast (magnetic ballast vs. electronic ballast, etc)



Thanks galadrial for giving me reason to experiment! Hooray for science!



cheers~!
