Hey, homie. You may wanna do a little more research. All these ppl that are telling you a dimmed ballast only pulls what its dialed down to are misinforming you. Yes, if you ARE using a Quantum dimmable, you are only pulling what its dialed to..regardless of bulb. 1Quantum 1000 dialed to 50% is pulling 500. These other brands, ie Lumatek, Digital Greenhouse, etc, pull what the ballast is rated at, not what you have it dialed to. The people who said yes it draws what its dialed to are either using Quantums, misinformed themselves, or didnt see in your post that youre running a Lumatek. These other brands do not burn as bright when dimmed, but are still using their rated wattage. These were all considerations when buying my gear. ' found this' we can argue about this all day ! You grow yours ill grow mine !
