A 600 watt hps easily draws 800 with the ballast.. another 150 for extra ventilation

have you metered this?? as far as i know yes the ballast will draw more then what it is listed upon firing up but after the ballasts use less then that...Now i could be very wrong but i was under the assumption that my 600 was only pulling 6 at the lights on and less once the bulb is fired up.

i saw the link and will go read but i swear there are others stating the opposite... Guess the final solution would be to just go grab a meter from the garage and see what i get.

To answer our initial question, "How much power does my lamp really use?"

Bulb Wattage -> 150W
Power used at Startup -> 535W
Power used at Operating -> 372W

LOL why didn't you add the next line?

"Bulb Wattage -> 150W
Power used at Startup -> 535W
Power used at Operating -> 372W

I think the most important thing to learn here is that it costs almost as much to run a 150W bulb on a low power factor ballast as it does to run a 400W bulb with a high power factor ballast. "

So no, you're really not saving much of anything and you might want to look into a 400-600w after a couple rounds. The problem with the CFLs is the lack of penetration.
