How would you light up a sps dominant system?

I have 2 of the 4' ATI Hybrid units and I am not happy with them.
I have had 4 ballasts burn out and 5 of the LED reflectors melt.
ATI told me that part of the problem was that I hung the 2 fixtures side by side and caused the 2 units to overheat.
They still provided me with replacement components under warranty, but I didn't appreciate ATI trying to partially blame me for component failure.

WTF am I supposed to do for an 8' tank 30" deep lighting?

MH, LED and T5 are great options, but educate yourself about the limitations of whatever drawbacks the fixtures may have.

Well the way ATI fixtures are designed to cool ,is the air is pushed down from the fans on the top of the light and the air is forced out one end of the fixture. Blocking the end of the fixture is like covering the top of your toaster and being mad your toast got burnt.

6 inches of space between the fixtures and no canopy should provide sufficient air space for cooling. There is very little hot air coming out of the end of the fixture.
I think that the plastic reflectors were a design error and the ballasts are not heavy duty enough.
The overheating issue does not explain failures in both fixtures.
