Find out today how to use the latest Kessil AP9X for some very specific tank shapes, sizes and reef tank types. We show you how the newest AP9X can be the right tool for one of the most challenging tanks out there, the mixed reef tank!

Great job. Kessil makes a great light (I'm biased I guess since I run the a360x) .
So I watched this twice and both times the same thing crossed my mind regarding the 60 gallon test towards the end. You recommended both color and intensity at 20% for LPS I think. The next test was with mixed I believe because as you said SPS turned out to be whack a mole. In any case you went with an intensity set now at 55%.
My question is this. Is the new ap9x too much light for this tank considering you are running it at less overall intensity. Assuming intensity = power (which I may be wrong). Conversely how would a single a360x mounted at 10 inches running double the noted intensity compare with overall results.
Meaning a9x is 2 arrays vs 1 single in the a360x. A hobbyist would save more money by using a single a360x provided it met the par requirements. Just curious.
Great job and thanks for putting this out.
Great questions, I'm happy to clear this up a bit!
First let's talk about the SPS test, in which case during the mounting height test you get an idea of what 100% intensity looks like from the heat maps where there are points of 400-700 PAR near the top of the tank.
Because our goal for SPS dominated tanks is to hit 200-350 PAR throughout 70% or more of the 108 data testing points (6", 12" and 18"inches deep in the tank) we start to play that game of lowering the intensity to a point where the top 6"inches of the tank doesn't get blown out above 350 while at the same time providing enough output so that 12"inches and 18"inches deep in the tank stays higher than 200 PAR. Hence the whack-a-mole game of robbing PAR from the top to serve the bottom or robbing PAR from the bottom to serve the top.
As to the A360X's performance in the same 60gal cube...first the AP9X is not a direct one-for-one version of just two A360Xs in the same body. The size of the Dense Matrix LED clusters are different as well as their placement inside the lens AND the AP9X has included reflectors that completely change the dynamics of the light output (which is why you see two "humps" in the PAR data at the top.
Because of that comparing the A360X to the AP9X is pretty much apples and oranges. However the A360X loses quite a bit of light and PAR output when you go beyond that 8"inch mounting height we found as "optimal"...optimal meaning we stop raising the light when more than 15% is spilling out of the tank. For the AP9X that was at 10"inches yet for the wide angle A360X that was only 8"inches.
As I mentioned near the end of the video, the A360X is a super wide angle flood light; the T365 is a super narrow angle spotlight and the AP9X is somewhere in between and because of that we just need to use the data to make the best decision for what works best for what we are trying to accomplish in our tanks.
Hopefully that helps clarify some differences, but don't hesitate to ask if you have more questions. I know these lights pretty intimately at this point! LOL.
How would this light perform on a IM int 112 mixed reef. 3’x3’x20”?
So I know we’re talking about the new kessil light here but since you’ve referenced the a360x many times and it happens to be the lights I run @8” above the water I might add,Great questions, I'm happy to clear this up a bit!

Do did 60 max intensity With sps?Over the 24 cube I ran max at 60% intensity at 8 above the water surface. 12 hour schedule with 3hrs up and down ramp. If you have either the controller or the puck you can set a similar schedule and use the acclimation feature to adjust.
So I know we’re talking about the new kessil light here but since you’ve referenced the a360x many times and it happens to be the lights I run @8” above the water I might add,
What is the optimal intensity for A360x?? (I believe you said the optimal color settings are identical) I’m working on a mixed reef with sps up top/upper center and lps on the bottom half
Hi everyone, first post!
@BRS, my question is along the same lines as Scorpius' except I've already ordered the AP9X from you guys (I think I probably made the first purchase). I thought it would work for my 120 gal mixed reef build based on Kessils' claim that one unit would be adequate for a 48x24x24 mixed reef. Needless to say I now have some buyers remorse after watching your rundown on the AP9X. A second unit is out of my budget. Would I have been better off going with a pair of 360x's? Thanks in advance!

The AP9X uses the same app as the Kessil WiFi dongle. Totally different than the AP700. You can also connect a spectral controller X to the light if you prefer wired control.Couple of questions... Have they improved the software of the AP9X over the temperamental and buggy AP700 software? As I recall, you guys switched from the AP700s to A360Ws because of the inflexibility of the AP700 software on the BRS160. Also, does the AP9X have smooth transition ramping like the 360s and 160s, rather than the stepped ramping of the AP700? As a former AP700 owner, I thought the hardware was amazing, but the software left much to be desired. If they rectified these issues that plagued the AP700, I may consider getting back into LEDs with the AP9X.
