For future proofing and as a rough estimate look for lights that have 120w or greater output.
Price and color your choice.
One Nicrew 200W w/ the $50 timer is one of the more affordable options.
err maybe a150..
Your AI Prime (
Max Power Consumption: 55W – 59W at maximum output) is not future proofing.
There are probably a dozen lights in that 120w-ish range. Some you heard of some you unlikely have heard of.
Micmol Thor, Nicrew, Noopsyche, Popbloom, GHL Mitras 7204, Reefi (actually a good choice as well ), some "clones" off Aliexpress, and a bunch of "not quite" generics in the 100w + range that are inexpensive enough to be fine till you want to blast the tank.. In other words replaced.
They will likely be fine for some high light corals in the upper levels.
Keep in mind your Kessil is "only" 90w and aging. It is controllable. Add $110

A new Nicrew 150 w/ controller is about $300 at Amazon.
Things change.. doing future proofing is tricky.
Quanta is supposedly ( sorry until physically present it is, in the old speek, vaporware ) coming out with a 10v analog controller most likely at a fair price.
Good for Kessils, older Nicrews and even new nicrews with the add on. New nicrews are not 10v compatible out of the box.
You can eliminate using price, app, cloud , hard wire control, base "color", focused or spread lighting, watts, brand, If it has a tank mount and it is extra and at what cost. ect.
Since you may be used to spending "Kessil money" on lights the Reefi 2.1 with tank mount is $640 for 270 watts of infinitly tune-able color. Can't get any more future proof than that.. :)
Mitras 7204 and 7504 ( 2 base colors) is 131W max and $600. Replaceable led clusters (fairly unique ).
That $600 includes nothing extra like a mount. Well the software and cloud service is free.
So way more info and a bit scattered than you wanted and def. not "all inclusive".
I was curious as to what AI would say about a Nicrew 150 and sps. I started using the 200 then switched to the 150. 220's sort of an odd shape being rectagular moreso than the 150.
The 90 degree lenses would be nice for some more punch.
