Just bought the finnex fugeray for a 10 gal. planted that I just started. Only been running for a week, but so far everything looks good. Heard good things about these lights.
I use them on deeper tanks but not the fugeray (which is for shallow refugiums) but rather the Ray2 series. It does well with medium light at the floor of a 90 gal but the footprint isn't very wide (LEDs are fairly directional) so depending on the width of your tank you may need two of them.
