I'm interested in buying a 250watt HPS and I see that there are two different types, one has the balllast right in the hood behind the reflector, and one has the ballast seperate about ten feet away from the bulb. Are there any advantages to having an integrated ballast? I would think that with the light heat plus a ballast behind it this would be dumb idea. Also, how much heat can I expect from a 250w HPS? How strong of an air movement system will I need to control temperatures? And if anyone can suggest a 250w HPS system of a certain brand or place to buy it, that would be appreciated.
