Changing lighting, looking for Pro advise, 40 year saltwater veteran, not for newbies.

2 Orphek Amazonia 80's for the ends, 3 320's for the center.
No color tuning, just dimmable so you need to pick a "color"..
30 degree lenses 4.6' from light face to water surface (simple science)
The added "science" is once you get as many photons on the water surface as you can the water and glass will train most to stay there. And the narrower the lens but higher up cuts down on shading.

Got 6' of ceiling? Lights are about 1ft tall.
Being that far up pretty well takes them out of the "visual" equation..
Lower than that one can "highlight" the center island.
Waterproof and fanless as well.

60 degrees 2ft up.
All calculated using 30" dia "spot" size.
1120 total available wattage..
Tanks about 650gal right?
The icon 960's are full blown controllable but overkill for the ends.

Ask the experts at Orphek...my only advice involves aesthetics and physics and an alternate way of looking at it. No more, no less.

Kessil has sort of the same narrow beam lights.


Your orig. alternates don't seem much different than what you already have really.

I didnt think the 320s were still being produced and didn't even think about the 80s, that is why I recommended the 960s. I also figured the 960 icons controllability would be desired by the op.

I agree the 2 options they are looking at doesn't have much cleaning up of the current lighting as they imagined.

I used to help with a 900g SPS dominant. They had about 14 radions on it it was a 12 foot tank. They also ran T5s and halides on it though, phenomenal tank. Just my two cents on the how many you’ll need.
