They are on sale for 59 dollars at the moment. And you can exhaust a cool tube using just a shitty round plastic fan from wal-mart with some ducting taped to the back. Its not ideal, but its cheap and it works as long as you don't need a carbon filter. Lol, if you don't believe me, just look at the grow in my sig, and thats with a 1000 watt hps. If you're interested, I'll show you a pic of my ghetto exhaust fan, but I do HIGHLY suggest getting an air cooled light, otherwise you will be fighting heat forever. Not to mention you won't be getting the max potential out of your 600 watt because you will have to keep it pretty high above the plants to not burn them with an open air light.

Also, these are just a bit more expensive than you were paying, but they come with a cool tube.

I got my cool tube 1kw hps w/ hortilux bulb upgrade from them shipped for around $320. I ordered on a friday at 6pm and i still got the light the very next tuesday. Only thing I've ever ordered from them, but from that experience :thumbsup: :thumbsup:
