Step 1: Purchase LED Light String
Step 2: Unpack the LED Light String and Stuff It in the Lamp Fixture
It's best to clean the fixture first since it's probably a bit dusty and dirty if you've purchased it secondhand. To do this I usually just soak it in soapy warm water and then rinse it off.
Take the light string out of the box. It is probably neatly bundled and strapped with a twist tie.
Undo the twist tie and tangle them up a bit. It's going to look better with LED lights pointing in all directions.
Step 3: Finished!
There are as many ways to put on finishing touches as you can imagine. You could potentially mount it as a standard light fixture or put it on a nice finished plastic or wooden base.
Step 4: Finished and All Lit Up!
Looking forward to seeing pictures of what other people do with this. This is a simple project that almost anyone could do.
My only caution would be that you are working with standard house level voltages. Be careful not to pinch or potentially short circuit the wiring of these LED light strings.
