You sure don't want Kessil A500X's WITH Stratons.I just picked up 2 a360x’s to use along with my stratons on my new build, not really for par or fill light just shimmer. The last time I used a Kessil was for a 20 gallon tank so I can’t speak to how they would work. Looks like the 500’s would work along with them. I temp mounted the Kessil’s and the Stratons really mute the shimmer
The A500X is about 8 times more powerful than the 360. It's just too much unless you want to turn them way down.
