Product above. I could only find one thread about this, and nobody mentioned having actually tried it. But for 55 dollars, that seems like a good price for LED lighting for a 20L. Naturally, my question is, will this be sufficient for medium-ish lighting? I'm probably going to give it a shot.

I wouldn't part with $55 for a light fixture with only 4 leds. There's plenty of other choices on the market that would perform much better for the money.
225 Gal, Glass "Reef Ready" w/ dual Iwaki Pumps & 2 Ocean Clear inline filters. Makers 72" heat sink w/ 12 NanoBox V3 led arrays, custom built CC drivers. All controlled by a BlueFish "mini" Led Controller. iAqua Aquarium Controller , and a 20lb CO2 system w/ Milwaukee Ph Controller.
About 4 months ago I tried the LED puck type lights made for under counters. They do look good but I would have needed about 50 or so to have a chance at growing plants(100 gal. tank). I did end up buying the (6)Grobeam 500's and the light from the pucks looked yellow next to the Grobeam.
I have seen those Home Depot lights in person and they really aren't very bright, you would need several of them to even have a shot at growing anything but low light plants. For the money you are much better off trying to build a DIY fixture or going with a preassembled unit made for aquariums.
