Try and find one that enables air cooling through the hood, or use a cool tube. If your using HPS in smaller spaces this is almost essential in my opinion. I don't know if you can really get away with having an HPS just sitting in your closet with a fan at the bottom blowing up the heat, you have to take into consideration that even with a carbon filter/extraction fan at the top of the room, unless its directly connecting to the hood/tube your gona have heat coming off the bulb which will have to rise and then be taken out the room. Intercepting the heat before it hits the plants is the only real option.
