I received several package of the warm white versions, but they are not setup for 12v. Indeed it doesn’t appear that there are any resisters in line with the LED’s at all. They run beautiful at about 3.6v the forward voltage of the LED’s but at 12v they will burn up immediately. If you verify the voltage by trying them at lower voltages first you can add your own voltage regulator to the front but if you just connect immediately to 12v they will let go their magic smoke. Once figuring out why the first strand I connected burned itself up immediately they are otherwise now running very nicely on a 3.3v power supply. The color is not exactly “warm” but is warmer than the cool white.
