Thanks Ross, That's kind of what I was expecting to hear. The light meter I have is a cheap one, but it is giving me steady readings, and trails off smoothly as distance from the light is increased. This leads me to believe that it's pretty close.
The light is almost flush with the ceiling, so I'll have to rethink the bench set-up to increase the distance. Oh well, it wasn't that great of a setup to begin with.
