Help with lo tech planted office tank

What would also concern me about those LED strips is the lack of spread...most fixtures designed for aquarium use have diodes packed pretty closely together so that you get light over a greater surface area. LEDs are much more directional than tubular bulbs, and you don't want a "spotlight" effect happening in the tank.

This is the LED fixture I'm using on my 20 long and it's considered low, barely medium, lighting...48 white + 24 RGB...pretty big difference between that and the number of LEDs on your fixture.

If you're going with mostly mosses, you wont need much total light, especially over a 20 long which is pretty shallow. A few CFLs, a T8/T10 or T5NO fixture would be plenty.
 
Ok, maybe I'll just pick up a 24" t8 fixture at hardware depot.
I can get a double bulb fixture for less than $20. At least it's something for the moss. I'd hate to go through all the trouble of aquascaping and dry starting the moss, just to have it all die off and have to drain the tank and start over again.

From what I can find, it seems like 6500k is an ok color? Or should I go with 8000k or even 10,000k? Or if I get a double fixture, one each?

So far, it looks like I'm just going to be doing xmas moss and mini fissidens.
