Anyone used one long enough for bulbs changes? I,m going to purchase a 6 bulb 24in. unit. Looks like T-5 users on some of the Rc forums are barely getting 9 months out of the bulbs, on various units.
Thought T-5,s were suppose to last 18 months.

And the fancy high priced properly cooled units were to help that. So if I switch from my halide my bulb cost doubles every year?
I was hoping to get about 14 months from a set.
