I haven't seen an AI Prime turned on either, but of all the LEDs I've had experience, I like the AI Hydras the best (over Radion and Hydra even), and the Prime is similar.

Not sure what kessil's older model was but their LED chips layout that they implement in the current fixtures should have little to none disco effect. Most of the LEDs on the market comes with individual optics on each LEDs and that causes (along with other factors like water surface refraction and so on) the disco effect. But lens have come a long way over the last few years so I guess the newer fixtures, like AI prime, will probably have less disco effect compared to older fixtures. I looked at some AI prime videos and I can clearly see what colours of LEDs the fixture have on the sandbed; the camera probably picks these up more than what can be seen but still, its there. I am yet to see a kessil video that shows individual colours on sandbed.

But seriously, no disco like my last 2 LEDs... The Maxspect Razor had disco until I put a single layer of ziploc baggy over them... and same with the Evergrow until I put half pong pong balls over each LED. The Prime has needed no mods. It appears they've began to realize what I figured out a couple years ago that LEDs need to be slightly diffused (no clear lenses) so the Prime has slightly cloudy lenses. I can only speak for these 2 though as I haven't owned a Radion or Kessil... |
Yes frosted optics and lens helps diffuse the beams thus mixing the colour better. You should have contacted acted earlier and contacted those manufacturers to get the frosted optics/lens going
I think maxspect razor had the worst disco effect that I have seen until now.

I also run a ai prime on my frag tank in my sump and I can tell you it would drive me nuts if that light was in my main it is full on disco. I would have bought a Kessil 160 but my space was limited so I went with the ai and after all it is in my sump .

Thanks for the information. Finally someone with both the fixtures I am comparing (well I am planning on getting 160we but its the same layout as a360). Really appreciate your input
I guess I won't be disturbing my sleep tonight thinking which fixture to get
