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 58cm, width 1.5cm (actual production limit is 40cm, so the production size is length 29cm and width 1.5cm)
There are 42 LEDs per pcs, 21 cool colors and 21 warm colors, single 0.2W
