Lighting question...will this work?

[garvondavi]

I am planning on upgrading my lighting to metal halide. I visited 1000bulbs.com, and they seem to have very good deals on ballasts and bulbs...i was wondering if anyone coulod tell me if the 175 watt ballast i am looking at would be acceptable, i would most likely buy two. also, what else would i need to finish the set up, i know i would need to house it in something, but i'm not quite sure what all i would need besides the ballast and bulb. Thanks.
Here is the ballast: http://www.1000bulbs.com/product.php?product=922
there is also the same wattage ballast that says multi-tap, but i do not know what the difference is...any help would be greatly appreciated...THANK YOU.

Thanks, Ryan

The kelvin rating on the bulb is way too low for marine aquarium use, most dont go much below 10,000k, the bulb in that combo is 4200k, much too low IMO.
