Hi. Anyone with experience with The active T-rex type uvb bulbs?

At the 12" minimum (closest recomendation) The 100 watt flood bulb doesn't heat their basking spot past 86 deg. ( they routinely seek out spots in mid 90s now).

Also the hype about that type of bulb seems to be that while the initial cost(Around $50.00) is expensive it's cheaper in the long run than the 4' fluorescents ($12 to $18) that need to be replaced every 6 months. I just read in the accompanying lit. that initially the bulb will put out 200 to 300 micro watts per... after 6 months it's down to 50 Micro watts. Seems like replacement time to me. So whats the savings? I realize it's supposed to be convienient/cost effective not to have fluorescent and incandescent but incandescents don't cost much at all for heat.

I'd appreciate anyone with experience. Maybe I'm missing something?

Thanks,
Bob.
