I have a algae turf scrubber body that is build to accommodate the approximately 6"x6" flat LED lights on both sides. I've been looking at a bunch of ACKE brand lights on Amazon, but I am curious as to what others are using for their ATS. I'm strongly leaning toward the 35w version, but it just went out of stock. I'm in no rush, and would like to get this right the first time.
