I have been through alot of the pages on RC about the T5's! I have never heard anything bad about overdriving with the icecap 660! They even use it in the premade fixtures with 4 48'' bulbs! Can you give me a good reason or personal experiences not to overdrive? I am about to use 2 icecap 660's to overdrive 8 bulbs on my 90g mixed reef!

Thanks
Dustin
