Radion lighting question

[burtonboy182]

I have a 72" x 27" x 27" tank.

I am thinking of changing the lights on this tank from Kessils (3 x AP700s) to Radions. I have 5 Radion Gen 3 pros and was going to get another light so that I would have 2 over each section. It is a tank with the black bracing.

I will be having a mixed reef but mainly SPS and going SPS dominant at some point

Should I pick up another Radion Gen 3 Pro or should i go for a Radion Gen 4 Pro and slowly change over the other radions to the new generation Gen 4 pros? Its not something that's gonna happen quickly. How many of the Gen 4 pros would i need over this tank. I know having 6 gen 3 pros is over kill but i would rather have enough light instead of not enough.
Thanks

why are you switching from the kessils I have the radions and love the shimmer with the kessil and the color looks better to me and am thinking of switching over

You could get away with 3 gen 3's, but 4 would be more than plenty.
I would look into the wide angle lens to give you a little more spread.

I kinda like the Radion color a little better. I feel the blue on the Kessils isn't as sharp as the radions. The shimmer is amazing with kessil. Don't get me wrong they are great lights but i think i like the radions a little better.

I think part of my problem with the kessils is that i have them mounted in my canopy and its a short canopy so the problem is with my hood and not really the lights.

I already have a couple radion Gen 3 pros. I was going to do 6 over my tank. I have 5 and was going to pick up one more. Was just trying to decide if i get another gen 3 pro or get a gen 4 pro so i can have all 6 over the tank. I was going to do 2 in between each brace.
