What are your disappointments?
I have used both lights and would consider the 360x an upgrade in my book but I could see someone wanting to stick with the ap700.
You will absolutely be happier with the 360X the spectral controller is far more reliable than the AP700 APP
I have a soft spot for Kessils cause I like the shimmer and their controller is a breeze to set up but if you're unhappy with your ap700 then I would go straight to Radions. I don't think Kessils can quite match the colors that you can get with Radions and you will still have some nice shimmer.
I do to. I love the shimmer. Closest thing to a halide. Just a little disappointed with the 700. I am waiting to go reefapolza next week and see it in person.
so what do you like betterI run halides as my main lighting. In my opinion nothing beats them, they have the par, the spectrum, the spread (with a good reflector), and even the shimmer. But I enjoy the ramping up and down, and colors you can you can get with leds. I've had Kessil 360WEs in the past so I picked up a pair of 360Xs to play with. They got traded in for a set of XR15 gen 4 pros after only a week or 2.
I am in the process of setting up a new system and considering a t5 led hybrid system. Basically most leds I have seen cant compete with t5s as far as par coverage. ATI has a reasonably priced system ,with a new dimmiable version due out this summer. The next question is what led do I pair it with?
The app for the 700's isn't the best and I really wish that Kessil would update/change it. I have two AP700's over my 90g and I like them, but the app makes the transitions between color and intensity, well, not a transition at all. I think if you just set a color and ramp up and down intensity, you're good to go. As far as them shutting off randomly, I think that could be the driver? I had an issue where the incoming voltage to my house dropped and one of my 700's shut off completely. It wasn't until I was going to send it back that I looked closer at the driver and found the variable voltage pot. I turned down the pot all the way, then turned it up to where I thought 120v would be and plugged it in and it turned on. I believe that the pot was adjusted too high and simply didn't have the voltage to power the unit properly (just my theory). Anyways, after adjusting both drivers, my lights haven't flickered or shut off, but I also think the app drives some of the flickering and on/off issues as well.
These lights work and grow coral perfectly fine. If sps is your thing, then you'll need plenty of coverage to minimize shadowing, whether it be, radions, kessil, AI, it doesn't matter, you'll need a lot to cover the tank. I think T5/led hybrids are a perfect combo, just pick the led you like and go. There's virtually no difference between a xr15 pro with a diffuser and a 360x. To get the color blending the Kessil has, you need to raise the xr15 higher or use the diffuser, either way, the PAR numbers are virtually the same. It really comes down to personal preference.
Here's what three 160's and T5's did over my 22g. The T5's were only used for 6hrs a day and during the last year and a half on this tank.![]()

As a side note, I'll be switching out my 700's for 360x's. This will allow me to position each light independently.
I couldn’t agree more. I spoke with kessil there is an updated 4.0 version for the 700 to correct the flicker/shut off but I have not done it yet since I had bought the 360 x and plan on putting the 700 on my frag tank. But when I do the upgrade I will let you know if it corrected it
Cool. I'll have to reach out to them and maybe do the update? Is it software or firmware?
