Hello,
It’s good to see one actually do research befoe they buy. With that said remember, par is not everything, in fact really anything over 200 par is actually risky, and you can bleach your corals.
Both of these lights are good lights and you have done research on them. I would definitely research and study how others have grown their sps. A good example is per say people are going to hybrid t5 and led for more par. That’s probably an argument set for failure. If anything it’s lack of par because puck style leds have more shading. When you add the t5 in, one would have less because it’s a long tube.
So In short the two things in a hybrid is less shading and different spectrums.
Because your running a puck style led, your going to have hot spots and and low spots regardless if you run one or two. If you run one, the corners will be missed or edges regardless how you hang it. If you run two, then the center
Points or where the crictcal angel meet will be much hotter and basically the same effect as using one.
Now with that said yes there are tanks running puck style leds that are gorgeous. All I’m saying is based on what your asking this is going to be a problem regardless. You don’t need to blast sps with par, they need everything to be successful not just light. Another option is to find two good strip leds possibly. Not sure if you can find any now but two
Of the current marine pros (60’degree lens) would actually be better. (These are not the ic loop version by the way), but they would give you better coverage, and equal par to the hydra 5200 and or Radion. They would also give you less shading and more consistent lighting.
Again, not sure if you can find any but may give you ideas on how to light your tank. The ones you have choosen are good lights but will still lack coverage or, exceed coverage in the cross over points etc. I do know there are other strip leds out there that are really good. Yes they are not as well known as hydra, Radion etc but, probably in the same ball park, (you just don’t have the fancy name, or price).
Hope all works out and we get too see your tank with whatever light you go with. Do you have everything else planned out for the tank as well?
Sincerely
Sarah
