I am currently running a 36 inch Outer Orbit with a 150 MH and 2 x 96 PC's. My second PC ballast just burned out. That is two in just over a year. Current fixtures suck !!! Ideally, I am interested in 2 x 250 Watt pendants. I am a little leary of integrated fixtures. Instead of PC actinics, I will run either 10K bulbs and possibly 20K. So whose got what and how much ??? Anna - I may be interested in Geisseman pendants for the right price
