It seems to be just a hair better than the Fugeray, which is what I was looking at using on whatever Nano I went with.
Finnex FugeRay PAR Specs:
10" fixture: 49 PAR @ 6", 18 PAR @ 12", 9 PAR @ 18"
Finnex Fugeray-R PAR Specs:
Depending on the height from tank surface the regular Fugeray was tested at. And the RED LEDs seem like a nice touch. I know I have seen some takes with T5 lights, one 6.5k and one Pink Floura (sp?) light, and they look amazing.
