Mangrove Tank Lighting

[OldSchool Reefer]

I’m really happy with the mangrove tank so far and can’t wait for them to start growing but I have concerns about their lighting situation. They will be fine under the Radion XR 15 Blue that is over it for now but the spectrum should be more towards Daylight and less blue, a lot of that can adjusted out for the time being. The spread is the main concern at 8 inches I’m already getting overspill on the 24 X 24 tank and that doesn’t leave much growing room. Im looking for something with a narrow beam angle that will give me the highest mounting option with minimal overspill. The Kessils seem to be the best option so far. Recommendations?

I think you're right, Kessil 500 with a 35° reflector. If that's too wide probably have to go with soemthing DIY like I had to do on this system:
