No u cant. Not T5 HO you cant. I have looked plenty trust me. I may buy one of those cheap fixtures and simply install my own sockets and ballast or something. 6 bulb T5 HO's cost upwards of 300+. I paid 110 for 6 bulbs 2', 6 bulb ballast, and 12 sockets. Maybe I spend a little more for a fixture too but in the end I will spend less the half what they go for retail.
