Like Byron, my knowledge is extremely limited on LED light units.
I can offer what I have learned from the LED units I have used in the past, I did have a Beamsworks LED unit but for a high tech set up which ultimitely failed due to rampant hair algae growth that made me throw in the towel, never used that light unit again, still in the cupboard somewhere. That light would work on the right set up with C02 and routine fertilzer dosings but on a larger and more importantly, a deeper tank than what I had it on in the first place. Lots of lesson learned here.
But before that I had a fairly cheap ish LED unit that fitted over a 90 litre tank, I simply did not like how the light made the plants and fish look, made everything look kind of weird and out of place, it also had a 'moonlight' only switch for the evening, that was even worse and serve very little, if any, purpose at all.
After that, I simply went back to what I know better, T5 and T8 lights, I tend to favour the T8 simply because of the more varied colour spectrums and usually around 6,700K and my plants thrive on this, all sorts of low tech plants being various cryptocorynes, vallisernias, anubias, balansae and suchlike with also floating lettuce plants, a bonus is seeing very little algae to boot (touch wood it stays that way).
The only LED light I use, is on my 5 gallon shrimp tank, a Aquael Leddy Tube 3w sunny, absolutely perfect and surprisingly very good. Again, there are various low tech plants being anubias, windelove java ferns and balansae plants seem to thrive under this LED, I'd recommend this for the smaller tanks. Very little algae once more, a bit of green spot algae on the glass I reckon simply due to the tank being a bit closer to the windows and getting a little indirect sunlight, but my snails take care of a certain amount of green algae from the glass so thats all good imho.
But every tank is different, so what works on my tanks may not work on others. Very much a case of trail and error to see what works best, at least for me anyway.
