im useing a reflector of sorts.i didnt have any pics of just the reflector, but if you look on the far left of the 1st pic you can see what kind im useing. thats a different grow where i combined all the lights i had. it has a 150watt CFL in it, but i also have 1x1000watt hps and 8x4' long tube floros on those plants.kinda y i started to see what works better. i was useing all the lights at once for that grow.
i had alil bit of a hot spot prob, but only if i let my plants touch the lights. i did that 1 night when i couldnt check on them like i do normaly. they grow so fast that i have to move my lights everyday sometimes more. and with those crapy clamp type reflectors it takes along time to move them all. if i do the grow with nothing but alot of CFLs ill build a frame to move the lights all at once, and use just some sheet metal to conect all the light fixtures together and work as a refector. im thinking a shape like /--\ so the lights would come down say 2' on each side and the top would be about the same. the whole thing would move up and down by cables and pullies, so with 1 pull the top would come off and i can get to the plants.
i had a setup like that but with long tube floros and it worked well for what it was. its the 2nd pic. like that but with a sheet metal frame on both sides and top. i may have to run a few lil fans to pull the heat out, but nothing major.
and about the total lumans,,,, right now im useing a 1000watt hps hortilux light that is rated at 150,000 lumans (i think thats a close number im not exactly sure) and it cost me about an extra 50.00 a month on my ele bill. i want to see what the cost/yield is on CFLs and HPS. and the only way i can think to check that is to run about the same wattage in both kinds of lights.
