I currently am using 2 Kessil A160 lights and 4 T5 bulbs over my 75 gal reef. I am thinking of upgrading the LED lighting in order to support an SPS dominate tank. Was thinking of adding 2 Kessil A360 or 2 Radion XR15 G4 Pro to my current set up. Please chime in with opinions/suggestions.
Lighting setup.....opinions wanted

I have the Radion XR30 on my 45 gal. Reef tank, nothing better. GREAT GROWTH. Also have the MP10W , they work together in STORM mode.

So are your tanks SPS dominate tanks? I want to make sure I go with something that is going to support good growth in a specific type of reef, predominately made up of Acropora sp. I'm thinking my current set up is slightly under scaled for what I want. But before I invest more $$$ I want to get some opinions from those doing something similar.

If you like the Kessils stay with that brand. Hydras and Radions are nice units , cant miss with either. Keeping your T5s will help with shading/shadows. If it were me... I'd think about 3 LED fixtures for max coverage as well.
Hey I had a similar setup at one point on my 90 gallon. Ended up going to 6 t5 ati fixture. I like that I don't have to find the perfect intensity on LED's anymore. Also being able to still have a blue dawn/dusk mode is nice when using blue+ bulbs. Sure I don't have shimmer, but my corals are doing nicely.

Nope. Do you have a par meter? I'm guessing you are getting over 200 at the top of your rocks. I have an 8 bulb (for spread) supplemented by led blues but it's turned way down to 40%. 8 bulbs at 40% is less then 4 bulbs at 100%. Plus my tank is deeper. What you have is fine.
How high over the water are the fixtures? The t5 and the kessils.
And yea, it sounds like you’re close to the par numbers.
You do kinda need to decide (like we do all) the level you want to deliver.
If the fixtures are at about 12” you have plenty of light.
If it were all t5 it would be a six tube at 8-12in. You have more than that now most likely.
If you still want an easy boost, the 360 is the easy choice.
The radions would be the more fun choice. IMO. (More buttons)

What kessil model? 160?
You are probably running 6-800 par at the top of the tank with the t5 alone. Where the kessils hit is probably an additional 200-300 par.
Personally , I think you have plenty of light for an acro. 10-16 in from the top.
I had my 4 tube t5 led 8in from the top and the growth was explosive. And my Led was WEAK....
