Congrats on getting another tegu, make sure to post some pics! I've been using uvheat bulbs for awhile and I like them. The first two I had were 100 watt active uvheat from Wild Inside; they both burned out in 2 months. I then tried 3 100 watt T-Rex ones, I have to put them at 12" max to get enough heat. One burned out in a couple months but the other 2 have lasted over 8 months at least. I also just got the zoomed powersun 100watt at $30 each it's more of a spot so it can go further away, hasn't burned out in the 2 months I've had it.
