Lights use almost double the wattage!!!

[extinctx11]

This threw me into a loop,

MY 250W HPS uses about 450Actual watts (about 4Amps @ 120volts) fully warmed up

And my 400W HPS uses about 700Actual watts warmed up.


This is killing me beause I designated 1 15Amp breaker (only use 70-80% of a breakers rated amp) for 2x 400W Lights, but now I can see that just one will almost max it out! With the fans and the one 400W HPS Im around 8.5Amps total.
