Its just two 42 W 2800K CFL lights stuck in a bake-a-round I got off of ebay. Then I connected both ends to dryer tubing. One tube to an intake slot and another attached to the inline fan that propels air across the bulbs, cooling them down.

Then I have a couple smaller cfl's attached to the side for extra lighting for flowering, One is 13watt and the other is 20 or something. Made those small because I don't have a cool tube for them and didn't want them running too hot but honestly temp has never even approached being a problem for this entire grow.
