Ha sorry didn't mean to overload you with info. LEDs are nice, but they are pretty expensive and it would be a bummer if it didn't work out and you were stuck with it. Honestly, I think a T5ho fixture would be excellent. It will be less expensive, be plenty bright, and your plants will love you.
The problem with plants is that its not just about how much light, but also just as important is what kind of light. The led fixture you're looking at isn't "ideal" for plants. It skips the key parts that are good for plants in favor of being more visually appealing. A t5 has more of a shotgun approach, hitting a larger range of wavelengths.
This basicly boils down to: unless you buy very specific emitters, which tend to be even more expensive, you wont get good plant light. The ttrade off with plant lights is, to us, they appear dimmer because you lose the visual light (yellows and such).
I don't wont to discourage you, I just don't want you to make the same mistakes I made when I first jumped into fish. Yyou may get away with it with low light plants like Java ferns and such, but they wont "thrive". I'm also worried it will be a bit dim for your tank, but I have no personal experience. I think youll be very happy with a decent t5ho. All my leds are only supplemental lighting with fluorescent fixtures, but I have tons of plants.
Sorry for the essay, but I will say I typed this whole thing on a kindle, and that took some doing.
Edit: lots of spelling fixes. Stupid touchscreen.
