Lighting is really measured in Lumens so the Wattage rating on Lighting can be misleading.
and since he said he is drawing 4amps per light the real Power(watts) used is only 4amps x 120v = 480watts but puts out the equivalent of a "400watt" lamp.
Easier for the Manufacturer to just state the Lamps in Watts than Lumens.
That is why you see the Comparison on FL Lamps "150 watts @ 43 watts!!"
We grew up on 60,75 and 100 watt Tungsten bulbs so we are just used to those terms.

Also his 2 400watt lights equal your 6 Lights
2x400= 800watts
6x129watts= 774watts
But again it is hard to just Compare watts to watts because Watts is Power not how Bright it is.
