While my little tank is primarily acro, since it is so small I have to be very mindful of the LPS that is in there. The biggest boon to my LPS coloration and health has been "downgrading" to the 120 degree optics even though the 80 degree optics are more than wide enough for my tank. By putting the 120 degree optics on, I completely removed the hotspots and dropped my "max" PAR down significantly.
I have been using the "Deep Reef" natural mode with an 11 hour photoperiod at 27 feet depth and 40% intensity (17" deep tank) with good results now going on 9 months or so. After swapping out the lenses about a month ago, things have been looking better - especially directly under the lights. I had a cheap favia I got about a year ago that was plain purple and sitting directly in the hot spot. Since getting the wide angles, around each polyp I have a red ring, green mouth, and a dashed yellow ring around the colony - started really coloring up (I'll try and post some pictures later - i have a really good "before" picture of the colony so I wil ltry and take an after when I get home today). Same thing with an A. Bowerbankii right next to it that I thought was a plain red acan - turns out it was a reverse bleeding apple A. Bowerbankii and my hot spot was just too bright.
When it comes to the Radion on LPS, it is very easy to overdo it. I still have a recovering lobo after 9 months with the Radion because I overdid it in the beginning. Just go slow and you will be fine. I also really like the wide angle lenses and they are only ~$35 per set.
