I have all 3 of the fixtures mentioned except the Finnex Fuge ray 10"The fuge ray is 16". I got the Finnex gooseneck because it would fit a framed tank. It is entirely unsatisfactory. Like all gooseneck lamps it is very difficult to maintain a precise position. I would almost offer it for the shipping cost except I wouldn't want to accused of palming off something unsatisfactory.
Just by observation the Fluval produces more light. The Fugeray produced sufficient light to grow my Crypts, wisteria enough to require monthly trimmimg so the plants don't over run the tank. It also maintained an anubia w/ minimal if any growth. The Fluval tank is new and it produced diatom growth on the glass when the photo period was the same as the Finnex. I just got a timer for the Fluval and I will install it tomorrow so I can shorten the photo period. IMO the Finnex legs are too short for the illumination angle of the LEDs. There isn't a wide enough dispersion of the light so the light appears in a narrow band and doesn't light the tank evenly. I wonder if the legs were kept short to help with a low light output.
I hope this helps, if you have any more questions feel free.
