What kind of DIY does it require besides some sort of hanger?
I believe most come with bare wires that you would need to solder to a power cord. At least the one I ordered has bare wires. I have a ton of spare PC power cords so that's not a big deal.
Not saying this is difficult to do but not sure how many have a soldering iron.
If the unit I get works and I don't fry the LED, I plan on using a Kessil A150 gooseneck clamp.
