Looks like you probably have the HUB-8C. I notice it has NEMA 6-15R recepticles in the side. This usually means 220V. If you plug a 1200 Watt fixture into a 220V circuit it will draw~ 6A of power. Per the unit, each receptacle is rated for 15A, so 2*~6A=~12A per receptacle. I'm not sure why they have a limiting factor on the wattage?? If it were me, I would just run it. **NOTE** I was a commercial electrician for a good number of years so when I say "If it were me, I would run it"....I also know that I would likely be able to fix it if I overdrive it. So take that for what its worth but I truly think you could get away with it.
