I am not an electrician, but I play one on TV. 
Looking up basic info on the Kind LED Tech Specs show that those lamps pull a true 650W each. If you are on 110 voltage, then each will use 5.9 Amps. You may wish to check to see what the amp level is on your breakers. My breakers are mostly 15 Amps; however, some newer houses use 20 Amp breakers.
Two of those lamps will be putting ~12 Amps on a single circuit, plugged into the same one.
Again, this is just a rough estimate. Nice light choice, btw.
""If youa re in EU and using 220, these figures are not accurate.
