So I just unraveled about half of a standard 5m reel of LED strip onto a 2 liter plastic Coke bottle gaffed to the FilmTools lantern lock jig. Works great, and powered by a 190WH v-mount has given me 2hrs, with battery remaining. Still don't know how long it will last total. Crazy I never tried something like this until now.
Also, just yesterday stuffed some LED strip into random parts of my car, in an around the dash, on the visor etc, and had it powered by my cigarette lighter https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Very cool what you can do with this stuff. I'll be shooting a little scene with the China ball / and some night time car stuff in a couple days.
