The CFL chandelier I built @ walmart has 16 - 26w cfl @1700 lumens each.
That on just one socket, for one plant, one inch away! I'll be adding another chandelier identical but with 40w cfl or bigger if i can get it. The first one set me back only $45 or less. I also just used the extention cord they're pluged into to hang them. I also use a mix of the 56k and 33k spectrum bulbs in it. It's definetly bright and working. My jewel is pushin 7 wks old, flowering 7-10 days and is only 9-10 inches tall, 13 inch canopy, and 3-5 inches of preflowers and branching on either side of the stalk! Dang near as wide and bushy as it is tall. Solid foliage from ground to top. Dozens of juicy nodes all grouped within mm's of each other.
