Briefly, I use a compact fluorescent light (see
http://www.lightsofamerica.com/megalite.htm) in a 10" aluminum reflector
with clips holding test patches along the rim.  The clips also hold the
reflector 1" above a white Formica counter, so that air can enter there and
be vented out the top, near the light base, where I've drilled vent holes.
To help assure evenness of light, I rotate the reflector 1/8 turn, 7 times
during the 600 hours.  (If you look at the light you'll see why the rotation
pattern.)  I'll try to get a picture on the web at some point. That shows
how the setup looks.
