SpongeBob,
Yes, it is a very good site, I have been corresponding with the owner of the sites for a few months now, and she knows her stuff.
One of the biggest things that I have established through some basic research is that the diachroic lights with protective lenses removed, they are used by a few people here in Australia, and are not only useless in most cases when trying to obtain useable amounts of UVB, but are also potentially very dangerous to both humans and more so the animals in the viv's, one becasue they produce dangerous UVC and two because the height of which a few reports have recommended the bulbs be positioned would bring the animals close to dangerously high temps, and 3 the possibility of a bulbs breaking and hot molten glass spraying everywhere, hence the reasons the covers are glued on.
Anyone using these now, should seriously consider changing from them IMO.
SLacka I tested a NEC blacklight with Hugsta, and from memory the results weren't that impressive at 12", I will try and track down the paperwork.
Reflectors do intensify the UVB in the few tests we carried out, also lowering a florescent tubes if possible will increase the lifespan of the tube before the need to throw out.
