So let’s assume you can hang your lights as high as you want and that the frag tank is set up completely for growing SPS. What is the coverage of a single Radion 30 Pro? For a 4’x8’ frag tank how many would you need to get around 400par?

Although I know you are trying to help this data is a little misleading.Like 8 yeah , the pros hang them @ 24" and shoot for 300's so they are turned down alot, its about the coverage , I would say your better going with new hydra 64 for the same price and more than double the coverage,
He has a 4'x 8' tank
In this case I'd go with 1 pucks spread over the length evenly. Like 15pros or primes hd Place apart this will achieve optimal spread and coverage.I know what the chart says , but if he is doing SPS then the more diodes you have the less shading , that is all , it was not about peak output, total power ,or anything other than being able to get more bulbs over more area for less shading. I ran 2 g4 pro on a 24x48x16 tank , then I ran 2, 4 puck units so 4 pucks vs 8 and the SPS patterning and growth was insanely better just due to the lights placement vs the other (blanketing effect) , kinda like how photons and reefbreeders balck boxes blanket so well because there are bulbs everywhere
That’s the tough pill that is hard to swallow on those. After 4-5 years or so, If they’re still working you’ll get about 25% ROI by selling themI should post the financials on this topic. Btw I am assuming after 4.5 yrs the lights you are using will begin to fail or be completely obsolete.
Selling the Radions I think you are safe there on 25% residual value. I would argue that nicely kept ATI fixtures would also fetch 25% resale. However my friend has some Radions and he has some mortality after year 3. I have heard that ATI T-5’s go for ever. In the end different strokes for different folks. But having to use three of them in a 2’x4’ tank sealed the deal. Thanks guys for the input!!That’s the tough pill that is hard to swallow on those.
