Well, that was a fucking waste of my time and stress to the girls. In an effort to keep up tent temps, I was going to mount the driver on the light. It seems like the Mars 6500 never intended to have the driver mounted to the light. The driver and the dimmer both have a mounting plate, but there's nothing on the light to mount it to!!!
Unlike the sp3000, the top part of the the 6500 has no mounts.!!
I guess I have to throw my oil filled radiator heater in the lung room. I really didn't want to have to do that.
