Love my two primes, only gripe is that they’re noisy, not loud, but the fans are noticeable

What Kessil A360X owners say

I’ve been running 3 a360x lights on my 210 reef for a year and I love them
@MileHighReefers on YouTube
As someone who has AI’s on my main tank, and am going to use kessil on my second tank; I’d recommend getting the a360x. You can start with 2 of them and should be good for your needs.

I have 3 point source led lights (kessil a360x) over a 5 foot tank and I wouldn't recommend something similar for 4 foot tank. T5ho or reef brite led supplement will be essential because otherwise only about 25% of the rock work will be suitable for spa. They'll die in their shaded areas.
