I've added four more 26W "daylight" 6500 kelvin bulbs and four more warm whites. The light bar was a beast to build; I cobbled the parts together from Wal-Mart and home depot, but they hang and are pretty evenly distributed. The plants have been loving the light and four seedlings I put in there have grown all week like... well, weeds.

The fan works surprisingly well, and is quiet too. I manage to sleep in the same room with no complaints.
