These are brand new in the box Smart LED Christmas lights. 1 set is for a 5' Metal or Wood Base Christmas Tree and the other 2 are for 2' Metal or Wood Christmas Tree base. you must make the tree bases though. They are not included. They say these lights are programmable. I know nothing else about them. My mom ordered them thinking it was trees and all she had to do was set them up. She's 80 and didn't understand what she was buying. Please read the photos of the description from the website where these were ordered from.
