If you want lighting, use 12V LED strips with good quality white LEDs. If you don't turn it off with an actual switch that cuts the power supply, that will discharge your battery completely in a few days.īesides, being RGB LEDs and not white LEDs, the white light quality is terrible. So, a 2m strip with 200 LEDs will use 200mA. WS2812B uses about 1mA per chip when it is off. Note WS2812B is very inefficient and these strips draw a lot of current even when all the LEDs are set to off because the chips are still running and waiting for the digital control signals, and they are absolutely not optimized for low power. It is not possible to wire them in series for this reason: the one that uses less current would get all the voltage, and die.
