So, with my new meter and a new arcadia 34" 12% bulb with the bulb placed 1.5" above the screen and all measurements taken from the screen top, I get the following readings.
2" 113
4" 75
6" 56
8" 45
10" 35
12" 25
I'm a little disappointed with the results according to my meter. I was hoping for about double the output with the new Arcadia 12% bulb. My outdoor readings at 11:00 A.M. with a Seattle cold wet overcast day is at 50. The UVB here in Seattle is probably only a fraction of what it is near the equator in cameroon so I'm thinking I need a considerable increase in UVB output if I even want to come close to equatorial shade conditions in my terrarium. Unless your chameleons perch within 2" of the bulb itself I don't think the 12% bulb is enough for my desire to mimic UVB conditions close to the equator in the shade. The basking area in my enclosure top out at 70 and average 40-50. However comparing the Arcadia bulb to the exo terra Cfl 10.0 that I was using, it was a huge improvement .
I also took readings of my 125watt mercury vapor UVB bulb and realized that exo terra lighting products are just plain inferior to their competitors. The readings were abysmally low, almost useless.
IMHO the Arcadia bulbs are better than others but still just don't pack enough punch at distances more than 6" with screen top enclosures.
What kind of reflector are you using? Do yourself a favor get this reflector and I'd bet you double your readings easy !!!

Also are you using t5 or t8 bulbs?
Also what kind of screen is it?
