Okay to the best of my knowledge: I have two Strand CD80 Supervisor dimmer racks, with only the normal 2x2.4kW dimmer modules. I'm presuming there is a compatible special dimmer module for dimmable 8' fluro tube ballasts. Is this correct? I hope to crack open the dimmer room and scan down the rack, if everything looks the same I'll assume no special dimmer modules were installed. My assumption is based upon the fact that our maintenance dept installed these suckers, and just cut straight into three raceways for power. My next question, how do non-dimmable fluro tubes deal with power distribution. It's unclear how, but somehow our current fluro sconce lights solely click on and off. I'm not sure if they are on a standard dimmer set to nondim, or if a special dimmer was installed, can nondim fluros play nice with your run of the mill CD80 dimmer? Any things I should be looking for when I get a chance to check that guy out?
