Ok all well and good, I did find a website or two that claimed this is the "new generation of T5's". Said you can throw this in your current T8 setup, and it will be just as good as a T5 fixture.
I'm not saying these guys are correct at all, for one even if the bulb is as good as a T5 there usually aren't reflectors in a T8 setup. But the T6 is being marketed as the future of flourescent lighting for aquariums. So, thoughts, opinions? There's so little info out there about these.
