I was going to go with Kessils but opted out to go with Radions. So far, I'm loving the Radions. Love the fact that you can change and program the fixtures. With the Kessils, you are stuck with one color whether you like it or not. I see a lot of people saying that the 10K Kessils are more like 14K and that the 15K are even more blue. You might want to look around to see what color you really like before spending $265 on each one.
