RedSea 90 x 2 on 48x 24 x16 12 pm-11pm blue ramps up to 100% over 1 hour white ramps up for 2 hours then 100% both channels 15,000k for 4 hours then 1 hour ramp down on white and blue viewing until 10 with 1 hour ramp down . so 11 hour photo-period with only 4 hours 100% intensity , most coral I have seen in the wild only gets like 4 hours direct light (if that) most is super in direct and much lower par than what people shoot for these days

BRS did a really in depth look at par and everthing in these light on diff tanks and multiple lights , I think youll find what they say interesting , I would guess my corals are getting 100 bottom -250mid level and the top sps gets 350 ish give or takeYes I think the blasting method is what leads to a knife edge environment, you'll usually balance on the edge of bleaching to obtain bright colours. It's amazing to think only 4 hours of peak light can create brilliant colourful corals in the wild. I wonder how strong that peak is.
