Answer: 
400w. This is calculated by:
1) 400w rating each lamp
2) multiply the number of lamps (1) x 400w = 400w
400w / 1,000 = 0.4kwatts
3) power x time = energy consumption
Then, multiply:
0.4kw x 1 hour operating = 0.4kw hours or 400w per hour

Answer: 
Hi i223a, this is different than a normal light socket.
You need a 600 volt rated Mogul socket for this product. The ballast needs to be a ANSI model M59.
No special wiring needed according to the Phillips Tech personal.
