Curious about how much light was hitting my plants I bought a light meter. I'm running a 600W MH during the veg stage. To take measurements I held the light sensor pointed up and at plant top level. Directly below the light I was getting 60,000 lux, but the light fell off to 35,000 lux on the edges. Not bad. I raised the light by 4" and things evened out somewhat, to 55,000 and 40,000.
I then played around with some magnet mounted home-made reflectors. The light on the outside edges jumped 5000 lux with the light sensor held straight up. The biggest difference was the amount of light reflected back into the outside of the outer plants. The reflector added 10,000 lux to the peripheral plant edges.
