my 600 watt light is rated at 95000 lumens. Does anyone know what height that rating is for? I know the lumens decrease rapidly as the light is raised, but what height is the base lumen number taken from?

The measurment for lumens is taken at 1 FT without a reflector.
ok, cool. So if it's at 18" or 24"(typical height for 600w?) does anyone know what the lumens are. I know there is a formula, but I can't remember it and if someone has done the calculations already that would be sweet!
How about this?
