I've thought about the camera thing. Especially since I have a 
"prosumer" digital SLR that is fairly good at metering. It doesn't have 
a spot meter though. I am seriously thinking about getting the Apogee 
flux meter. It would be an interesting exercise to measure various things.

Your aquarium sounds like the one some of us daydream of having 
(probably because we don't have to maintain the one in our daydream).

I have often wondered about applying an infrared blocking film to a 
shield in extreme cases of MH lighting heating up a tank.
