Kessil A360x Lighting question

I am setting up a new tank the tank is 72x30x32. It has been up and running for about a month and a half now. I currently have 3 A360x lights on the tank and the shimmer and tank looks great. I am getting back into reefing i have been out of the game the past 7 years and I had always used metal halide lights in the past with great success. My question is this enough light to keep SPS corals or do i need to add more Kessils if anyone has experience with these i would greatly appreciate it.

IMHO, you’ll need at least a couple more due to the depth Unless you are very careful with placement.

I'll try to be nice if you try to be smarter!
I can't help that I grow older, but you can't make me grow up!

Current Tank Info: 120 mixed reef with 40b sump, RO 150 skimmer, AI Sol Blue x 2, and a 60g Frag Tank with 100g rubbermaid sump. 2 x Kessil A360w lights, BM curve 5 skimmer

Without the add on focusing lenses they may struggle to punch down 32”. Also, shading will eventually become an issue.


Got back into the hobby ..... planned to keep it simple ..... yeah, right ..... clearly I need a new plan! Pet peeve: anemones host clowns; clowns do not host anemones!

Current Tank Info: 450 Reef; 120 refugium; 60 Frag Tank, 30 Introduction tank; multiple QTs

I am running 3) A360X's on my 180 gal mixed reef. I added 4 T5 for shading which really helped. You will at least need focusing rings because of depth and possibly a fourth A360X. The addition of T5's, if you go that route, seems to slow down the shimmer a little but still looks great.

Awesome thanks for the advice. I’m actually adding two more and have added the narrow reflectors to my deeper areas of the tank. Thanks for the feedback. I’ll currently have 5 now with the lights over the reef primarily.
