A ring of 16 individually addressable RGBW NeoPixel LEDs with a warm white (~3000 K) channel. Each 5050-sized LED contains red, green, blue, and white elements with integrated drivers, delivering vibrant colours plus a dedicated warm white for natural lighting effects.

The ring is chainable — connect the output of one ring to the input of another and control them all from a single microcontroller pin. Each LED draws ~18 mA constant current for consistent colour regardless of voltage variation, and no external resistors are required.
