I really know nothing of the Galaxy with regard to owning one,so can not speak on it with experience. Sounds like it may be the option for you. They actually seem very similar. Warranty may be better on the phantom (5year vs 3 year on the galaxy)


Im thinking though, that maybe if you were to go with say the Phantom... You would get the HPS-MH option, however, a conversion bulb will not allow you to change without changing the bulb. Two bulbs would be needed. A conversion bulb with a switchable ballast and dimmer would be very nice. Phantom 1000 ballast has the option to reduce power but not specify MH or HPS. I think switchable magnetics do though?

To reduce the output should not be problem due to the fact that you have the dimmer option. There are three outputs, Low-Med-High and that they are like a 1000-750-600. I say this because that ballast's printing on the side of it say 100% 75% and 60%. I dont know if that transaltes to 1000w 750w 600w. And...Im not too sure how the draw changes though. I would imagine less light means less heat and amp draw, but I'm no electrician.

I think that with any 1000w in a fairly small space an AC will be required in the summer. Not 100% sure but where I live it's probably the case. Probably has a lot to do with the temp around the space. Im sure you are more than well aware of that though. You probably are a more up to speed on the technicals but just thought I would add my 2cents.

Anyway Im kinda rambing....
