 direction of light rays

I'm going to go with CFL's. Now my question is instead of using one 200 watt at 1 stationary position or can I use two 100w in 2 stationary positions? Will it create the same yield?

I'm guessing it's better to go with 2 smaller bulbs, cover more area.
The only down side is light intensity is slightly lower. Which means light doesn't get to the lower branches as much
80$ light system with crappy reflector+25$ good reflector. Worked great for me 
Edit: didn't realise CFLs were so cheap :o 200 watt is on ebay for 30$ auction almost done

IMHO, the lots of smaller ones are better from a "many points of light" perspective as well as economy. You can get a shitload of 16W bulbs for cheap. I think you can get 4 for under $2. Three 4-packs will net you nearly 200W. Hell, just splurge and get four 4-packs, a handful of Y-splitters, and you're set. For fun, I arranged 8 bulbs on 7 Y-splitters on one light socket. Very bright! A home-made reflector made of printer paper (yes, I said it!) over the top will send wasted light to the plants.
Edit: Home Depot has Ecosmart 14W bulbs in 4-packs for $1.99. Each is 900 lumens or 64 lumens/W. I believe you can get them in 2700K and 6500K.
I suppose you have to consider the cost of splitters and such in the bulb cost equation ... but multi-point lighting from low-power sources is better, I think still ....

if you feel like just playing around/experimenting with cfls then at least go with the "outdoor" ones that have a 200+ watt equivalent
and run about 65 real watts.
look in the oudoor lighting section of your lowes/homedepot/

4x23W for $5. Get two of those and you're close to 200W for $10, plus another $10 for splitters & such. 8 bulbs spread over that little grow space ought to give pretty good coverage. Or get 16 (three 4-packs) of the 14W jobbies for $15. Both those setups equals 12,800 Lumens. All for under $25. That's hard to beat, price wise, compared to anything else.
Edit: Added picture of a little representative setup for basement lighting I'm playing with.
It looks like the number of splitters for such malarkey is n-1. So 15 splitters figure into the cost of those bulbs. Either that or rig up a string of fixtures. Another type fixture worth considering is a screw socket to plug converter that you can plug into a strip.

They're about the same price so there's flexibility in the design without much effecting total price.
Edit 2: The diameter with 8 bulbs is 15".
