Hey Tx... You may want to try like a TruValue or Ace Hardware. You can get a socket/cord set for about $8 then a Y splitter for about $3 - 4 and 2 100w CFLs for about $6 - 8 or maybe a little less. I think they will put out more lumens than the 48inch tube. Plus, they are easier to move around to exactly where you want them and provide more light in a concentrated area. Best of luck and get a small $5 fan at the least. And like BeIrie said... move them closer to the wall to help reflect light. That will help a lot.
