Hmm it's rated for 15amps, but says only 1800W, so 2 1k HPS probably wouldn't work. Oh well...you need to find out its allowed amperage and then add up your electricals to make sure they won't overload its current capacity.
Yeah, my pinned one has never really failed me either. I was just curious hahaIm sure it would work fine, but like dadio said...power surges etc...I would stick with the "pinned" kind...but thats just my opinion. I use one and its never failed me even with electrical glitches or whatever.
