You could use a cool tube. Or you could get an air cooled 1000 watt system. Or you can get a 400 watt system. I have one of those for sale. Click the link below my signature. All three suggestions will work. With a cool tube or air cooled reflector you can get the light alot closer to the plants but you still need to buy an exhaust blower with it. Or buy a 400 watt and you can place it somewhat closer because it does'nt get so hot.
