Something else that should be mentioned too...

If you use a 14k or 20k bulb, the PAR will be lower and you can go without the VHO's. 14/20K bulbs in the 400w range have a PAR similar to 250w bulbs in the 10K range.

10K = White
14K = White/Blue
20K = Blue

(The aboves are the norm, but ofcourse they vary with company)
