My setup is sorta amateurish, but it is working very well. I have an overhead dual 40inch flouro tube fixture that is hanging. I used aluminum foil to extend the reflectors out about a foot on each side to reflect down as much light as possible. Then I used industrial plastic zip ties to secure four 42 watt Ozone full spectrum CF bulbs. I have all the wire running at the top of the flouro fixture. That is pretty much it. Except that I have covered almost everything in Alum foil to reduce the light lost as much as possible.
