The secret to LPS success is......?

I wouldn't say they're at opposite ends. At least not for the euphylia that I keep. I have always maintained water parameters similar to the OP's, under 400w MH. I have 3 large colonies and they all do very well. I do feed my fish heavily, so there are nutrients in the water column. I never direct feed them.

My past experience is with MH
Currently using LEDs

Under 400w halides I kept a mixed reef in a standard 180.
Didn't have a problem with keeping anything under high light.
Softies, ricordeas, Lps, sps, clams, they all did well.

I believe it has something to do with the light from LEDs. I placed a Lps near the bottom of my tank and pretty much melted it.
My Lps are now off to the side in the shade.

Go figure.

Well, yah...you could say that NPS would be at the opposite spectrum of SPS, but even then, NPS require a strong water flow to maximize the amount of food particles they capture.
LPS and SPS are pretty general terms.
