The Kessil a80 is fanless, it's entirely passively cooled. I really like the color of these lights, however, if you are really into a lot of mods and like to try new things with your lights, you won't have those options with the Kessil like you would the AI.
Also, the spectral controller must be plugged into the light at all times. If you unplug it, it will revert back to the old settings that you manually set and it will not turn off without a light timer. Yes, you can put a kessil a80 on a cheap light timer and manually set the dials. You don't have to have the spectral controller to be able to use it. I'm happy with mine.
I have seen the AI light and messed with its settings. It's kind of frustrating to get it to link to the phone and there are some other technical glitches... But yeah, it does more stuff.... But who really needs lightning storms?
