Which reflector?

So I'm trying to decide if I should go with either a cool tube reflector or an euro reflector. My space is 7.5ft length x 2ft width x 5.5ft height and I'm going to be running one 600w mh/hps light. Any advice would be great, thanks.

So if your gonna get an aircooled reflector, your gonna need a fan. Why not use that fan to extract heat from the room instead and get a reflector that has better light distribution.

Yea I have a 440cfm inline can fan, so what do you suggest on the type of air cooled reflector I should get?

ok so why not use that massive fan you have, to extract all the air out of the room, no need to hook it up to the hood.

This is the type of hood I think rules the roost.
