You should have 92 watts with 4 23 watt cfls, around 6,400 lumens...if you can get a few of those and a few splitters 6 bulbs at 5000-6500k 23 watters that would be 9,600-10,200 lumens
You can get splitters for $2 at your local hardware store...usually smaller stores carry em, i had to go to orchard supply and hardware to get mine...kinda like an Ace
