very new to this... i was just wondering.....if your useing a 1000w light with a 1000w ballast for both mh or hps bulbs does that mean your using 2000w every hour you use it?.......thanks

The lamp doesn't draw any power; only the ballast does. So, if you have a 1000W lamp plugged into a 1000W ballast, you are using 1000 watts of power total, not 2000.

Actually, a 1000 w lamp and ballast draw about 1200 w; 200w is ballast loss.
