DMX512 is a protocol that sends data to lights over cables. It lets you control brightness, color, and more for each pixel. The RGBW setup adds a dedicated white LED, so you get pure light without muddy tones from blending reds, greens, and blues. This shines in spots needing clean whites, like stage designs or store displays. https://www.signliteled.com/products/flexible-led-strip/smd5050-addressable-rgbic/
