I found a lot of finished light strips online but they didn’t match well, so I made a set myself.
The light strip leads to three wires, the middle is the positive electrode, and the two sides are the cold-color negative electrode and the warm-color negative electrode.
Light strip parameters: length 40cm, width 1cm (note that Jiali Creation will add a 100 yuan process fee for V-Cuts below 1.5cm)
There are a total of 78 LEDs per pcs, 39 cool colors and 39 warm colors, single 0.2W
