Just FYI, CFLs emit most of their light sideways, not from the top or front as Incandesants. If you place an individual reflector on each bulb, you will be directing more light onto the plants instead of lighting the rest of your grow room needlessly. Suggestion... Tin cans cut up so they wrap arround lightbulbs and direct light to the plant. Secure with electrical tape. As you can see from the pic reflectivity is very good, I had to manipulate the lighting just so it would not keep ruining the pictures with the reflection of light
