Ok so here's the light I use for seedlings and small clones. Its a 15w UVB T8 for a reptile cage. I use the hand test to see what's bareable and I keep em a little lower but it seems like these UVB bulbs do noticeably pump UVB rays because the small CFLS wouldn't push this much heat CONTAINED IN the light and when I used them I had them nearly touching leafs. Are the UVBs not a good choice when it comes to heat and lighting for seedlings.
