sorry buddy its pure marketing as in its NOT possible to get the same amount of photons out of a BML 600 as a 1000 watt HPS.
Your comparing an input source of ~330 watts vs. ~1200 watts. you can do all the playing around with spectrum as you want, but a top of the line 1000 watt HPS will smoke a single BML 600.
Sounds like what I already said... a the Spydr 600 can replace an HPS1000w depending on which one. I said that above. How many people do you know that are diy growers using 1000w 'high end' HPS in a 4x4 tent? Seeing as how you care comparing electrical watt for watt, I can see why you are confused. Why don't you tell us what you consider to be a high end HPS fixture, and I'll compare the PAR readings for you.
