Refugium for 20 gallon

I'd like to setup a refugium for my 20 gallon long. Either purchase one or DIY. I've found plenty of recommendations for larger tanks but not so much due smaller tanks. I have looked at purchasing an aquaclear filter and then setting up a light for it. I'm a little lost on what light to use.

Does anyone have any recommendations for a refugium as well as lights?
 
There are a lot of options for refugiums. I had good luck with a smaller watering stock tank; they come as small as 15 gallons at Tractor Supply. Plenty of room for heaters, skimmers and so on, and it adds to overall water volume. I'd opt for a skimmer over a filter. Hanging drains/pumps aren't that difficult and can be dialed in quite well if your tank isn't drilled. Lighting recommendations are beyond me these days.
 
I used a cheap LED grow light from Amazon for my Refugium. My fuge is a 15 gallon tank I drilled, glued 2 pieces of acrylic together to make an overflow, and plumbed to my sump.
