T5 HO non-aquarium grow lights

[tang daddy]

The downside is that the grow ones do not have fans installed but if they're going in a canopy then no one will see it anyways.. also the reflector is not German polished high grade aluminum rust proof, 30% more reflective..... something something something.

But as you mentioned above, no seperate switches, active cooling, dimming functions, high reflective, water resistant sockets.
