well, if I find it to be throwing off too much UVB, I can put the shield on. This light came with a plastic cover over it's bulb, which I wont put on, a walmart 10 dollar light fixture, because I'm told it decreases the UVB, unless there's an issue. I'll also be afixing it to the very top inside the cage, he normally sits on a peice of wood 6 inches away or a rock that is more. This new halogen bulb I got runs so hot he sits on the floor alot and it actualy turned the screen white. Hopefully it's massive fillament will outlast the megaer lifespan of my other ones, plus it permits him to bask in locations other than only the branch. I do also have a larger shelter I just added (one of those half-pipe bark thingy's) so he can get out of the UVB if it irritates him. Hopefully I can get an exchange at the store. The store also tells me that they use said brand for all of their reptiles. I checked all of their beardies and they all seem fine. They have a couple dozen atleast, and I'd say atleast 10 bulbs? the cages house multiple dragons and every one of them is wide eye'd and alert and watching your every move.
The good news is, with petland remodeling and under a new owner they want suggestions. I plan on giving them a list of things that I need that they don't have. Reptisun 10's being one of them.
