Radion or Kessil

Could you put 2 Radion XR15W Pro on a 24” cube?
If you want or grab a xr30 gen 3 pro with the diffusers and o my all of these color blending and disco effects issues are gone. Plus it will only run you like $550 as apposed to $700 for two xr15 gen 4 pros
 
I am asking, because I maybe getting a killer deal on 2 BNIB Xr15w Pro Gen 4 + Reeflink also BNIB for $800 Cdn. Just hoping, i will find out on the weekend if i get it.
 
I have both and honestly it just depends on how you want to spend your money. Both are quality lights and bring out really nice colors from your corals. I really like the variety of controls on the radion and it's very fun play with. The kessils are sleek and simple and the shimmer is phenomenal.

The only thing I really don't like is after spending $400-800 on a light, you find out that you need to spend an additional $40-100 on the arm and an controls.
 
I have a Kessil over my freshwater planted tank and really like it a lot. For another option a Orphek Atlantik Compact would work well over your cube. I have the V4 and love it.
 
I like Kessil I have an Ap700 it's a monster and the shimmer is amazing. I run it with a guisemann t5/mh and 2 reefbrite xho.

The Radions color blending was awful. I took them off after 3 months and I went with 2- Kessil AP700 and have never looked back. Amazing colors and blending and controls are great. The growth is like I have never seen before my corals love them at 75% and my 3 clams are thriving in a 32” deep tank and they are in the sand bed.
the radion diffuser completely fixes this

And both are good lights I have tried both... I like the radion better and even more so the xr30w with a disfusser - my only complaint is the fan running 24/7 but it is pretty quiet
and you could get away with xr15w but I would just get the xr30w and never worry about wanting to upgrade or ever increase the tank size down the road

if you are into aesthetics, like I am, look at some pics with both lights over tanks... I never could appreciate the look of the kessils compared with the sleek modern looking radion
 
I'm running the G4 xr 15 on my 60 cube and a kessil h80 on my Fuge. I've found kessil is more plug and play. And radion more of a hassle to set up and dile in. I love both lights and would buy both brands again depending on my needs. Also you can add a aqua life t5 hybred fixture down the road if you want better coverage for higher light corals.

fwiw i run a gen 2 radion (soon to be gen3 pro!) over my 60 cube and don't have the color separation problem that people talk about. I run my whites/reds/greens at around 10% though, blues at 100.
I run my lights all at 100 at max peak except white lol white is at 10%
