We all know, well maybe not, that like you said in your first post (Still, I'm a believer in small HPS lights and combo HPS/CFL grows), dual spectrum works best for the entire grow. If you can't find out the par watts, call any manufacturer and they will tell you after a few forwards-it's not hard, just takes some effort, and not just searching these boards where 90 percent of the answers are: mh for veg, hps for flower-and get the most lumens-not!. I use to grow mh during veg and hps during flower. I use to go by lumens only but could not understand why my grows did not get any better/bigger when I went with the fancy/overpriced high lumen bulbs. Hmmmmm, I wonder why.
Anyhoo, yes I'm a firm believer of the KISS method, and there are plenty of great grows where people just look at lumens. Hell, my ave. yield under a 1000 watt bulb was around 34 oz's, and lumens was all I looked at. First time I went dual (600,400), same strain from clone-38 oz's and the plants were much healthier.
Here's a pretty good site-kind of old: Grow Marijuana FAQ, Cannabis cultivation - marijuana growing tips & photos
