I used to have a chart/graph/picture of the light output of this particular bulb/reflector setup - can't seem to find it now. The lumens definitely drop off when moved from directly under light, maybe I should just buy a light meter, I think they are under $30.
I'm trying to get all my phals, dens, cym, paphs all under the same light. I think I'll find a nice spot for them all - given the dropoff in light levels.
I found the link you were talking about by the way
