Actually these fixture are at the back of the hood(which is completly open), are at least 3-4 inches above the glass covers of the tank(my hood is similar to the one Buck has on his site), not to mention they were on for 10min max. I suppose air flow could be an issue, but I have easily 10 times more clearance than over the counter lighting fixtures using the same bulbs :shock:
I am not sure... Could have been fatigued in shipping, I guess....
