>>See I figure if I've got to buy one repti-crap bulb every 6 months that means I'm paying 200-250 dollars canadian every two year replacing these damn things when I can just go buy a powersun and it'll last 2 year and it'll only cost 80 bucks...
>>
>>Are these things worth it or are they not so good...I've heard mixed reviews....any comments???

Track down and read the following article:
Ferguson, G.W., Gehrmann, W.H., Chen, T.C., Dierenfeld, E.S. and Holick, M.F. 2002. Effects of Artificial Ultraviolet Light Exposure on Reproductive Success of the Female Panther Chameleon (Furcifer pardalis) in Captivity. Zoo Biology 21:525-537.
I do not recommend MV bulbs for chameleons except those in the largest of cages. I only use these bulbs in my enclosures that are almost 7' tall and 6' long. In these cases, the closest the animal can get to them is a foot and a half and the bulb is in a back corner of the cage where they can get far away from it. I do not use them for basking as well as UV and for the rest of the cage I use old reptisun 5.0 (over 6 months old) for ambient lighting and then a basking bulb away from the powersun. Too high intensity UVB for extended periods in chameleons in Ferguson's study showed decreased reproductive success. Chameleons are not bearded dragons, their physiology, habitat and sun exposure are very different. For anything but the largest of enclosures, reptisun 5.0 are the best even if they need to be replaced every 6 months. I'd recommend changing the powersuns annually.
