Thoughts about this bulb and how large of a screen it would cover?

How are these lights working out guys?
Ok cut down to 7x7 scraped all the brown off completely. Going to let it run ten more days and then we will see.
Ok seeing as I am going to cut the screen down I want to make sure that all my other parameters are in check.......
My intentions where to go 7x7 but I saw how it was filling in and knew my nutrients where high so I left it for now. But I can cut it down if you think it needs it.
Forgot to say, scrubber has been up and running for 6 weeks
Ok here are some pics of my 7x14 screen after 10 days. How does this look. It is lit both sides with 2 23w cfl spiral bulbs in standard Menards clamp type reflectors about 4" away.

Anyone ever use anything like these?
