So first time writing in this forum, but probably not the last

I am planning to run 2x400w metal halides on a 1meter long tank to avoid single light source shading of the corals.
But in order to avoid heat I would like to run the lamps one at the time whit 2-3 minutes of crossover.

-Will there be any problems whit the load on the digital powerbar?
-I have heard that I should only use the 4 outer sockets of the 6 on my powerbar for such high loads, is this true?

Parts involved…
