4-pin 10mm 5050/3528 RGB LED strip lights and 2835/3528 4-pin 10mm LED Strips.
5-pin 10mm RGBW LED strip lights
6-pin 10mm RGB LED strip lights
Not for 2-pin white 3528/2835 lights, not for dream-colour chasing LED strip lights, not for tunable white LED strips, not for 2-pin white light strips.
I received the package in good order, although the razor head is different from what it was before. Because the individual blades don't detach, cleaning is difficult.
