For nem I'll go with R420R.
My 60w is dimmed on 75% and I have some algae and coraline growing on the rocks. SOme rocks are doing photosynthesis !?! (Bubbles on some rocks)
I can't give review about the Orbit fixture as I never had it. It was my first idea to buy this, but finally opted for the R420R 60w. Can't give a review on this too, I never grow corals with this light. I buy two SPS
tomorrow, a frogspawn and a zoa.
I'll give you reviews, but everybody say they can grow anything with this light. For sure highlights corals won't be happy with orbit fixture.
