Look up what happens when AC power has a "lost neutral" - the two legs still add up to 240V, but one is below 120V and the other is above 120V. However, it has something that holds neutral in the middle - the transformer. North American AC power does the same thing, with 240V being split in the middle to make 120V twice. There is a critical flaw in that strategy. Your idea is to synthesize 6V by having two "banks" of LED in series with each other. You could use a 12V equivalent to WS2812B but it is even less efficient. Please do not get the counterfeit LM2596 from aliexpress. These LEDs use a huge amount of current, maximum 5A for every 100 LEDs, so that's a problem. If you want decoration, you can use WS2812B, but you will need a 12V to 5V buck converter. The 2200K 95CRI from this manufacturer is super cozy, add some 4000K or get the dual color strip if you want variable CCT. 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. WS2812B is a digitally addressable LED strip, it will use different current depending on brightness and color.
