I have a 7 foot 125g currently with a a360we in the middle of the tank, works great. We have anemones n softies. Was going to add another kessil to one side thinking 160 would be enough as we only have the 360 at 60% intensity now. We don't plan on any Sps. Kessil website lists 3 160 or 360. Any thoughts?

I have two A160's only supplementing blues for my Mh in my 36" tank. I have sps(you dont need that much), but quite honestly i dont think the A160's would cover even close the same area as the A360's. Im sure through time you will end up wanting to get corals that might need more light, so i would get ever though its overkill for now, other 360's over the A160's

I have a 4' 120 gal. with a radeon on one side and a kessil 360W sun on the other side. The radeon is much brighter then the kessil so I keep all the sps on the radeon side and a crocea in the middle so it gets both lights. Seems to keep my chalice and softies happy on the kessil side of the tank. I cant imagine if I had a 160 on it. I think it would be totally inadequate. Anyway, I'm going to upgrade the other side of the tank to a radeon so I can spread the SPS to that side too without concern.

I'd rather run a 360 @ 50% than a 160 @ 100% if both are putting out the same Par at those settings. I run 3 360we's on my 7'x2'x2' 210 Oceanic and have them at 70% and it keeps all my LPS happy down to the sand bed and "easy" sps like birdsnest and montipora thriving in the upper 1/3.

You are absolutely correct. Led fixtures are way too powerful and can bleach corals like theres no tomorrow.

A lot of the actinic light isnt noticed by the human eye, and a coral can be greatly exposed without our perception on "enough light".

I have my 160's running up to 70%, supplementing my halides.
Also runing a fixture at lower% will allow for longevity of the diodes.
Heres a pic of mine:
