need some help figureing out if i should do with a 6 inch intake hood style cooler of just a simple cool tube either way its air cooled.
ShootinBudz said:I pulled 2.5 pounds from two 600s in cooltubes recently, I was able to get the lights very very close by pulling outside cold air through the tubes.
After a year with tubes I am going back to hoods in most cases because if your fan circuit breaks or anything like that, ,if the power goes out and it fucks up the synchronization of fan timer and lights your bulbs will explode.
The best situation for cooltubes is vertical.
