RGBW 12mm linear lighting combines RGB color mixing with a fixed 3000K warm-white channel for color effects and white light. RGBTW 12mm linear lighting adds tunable white adjustment from 1800K to 6000K, allowing the white-light appearance to shift from warmer to cooler tones alongside RGB color control.

For 12mm linear lighting, use the universal in-wall extrusion and lens for recessed drywall installations, the universal extrusion and lens for surface-mount applications, and the universal square 45-degree extrusion and lens for under-cabinet or directional lighting. Each profile accepts 10 to 12mm tape light and uses a frosted lens to diffuse the light.

Plan for a compatible power supply sized to the selected 12mm tape light, total installed length, and its specified maximum run, with wiring that matches the installation layout. For RGBW or RGBTW lighting, plan a compatible controller and the required connectivity, such as a lighting gateway for DMX or DALI control or a module for Zigbee control, and use compatible connectors where needed.

Plan each run around the tape light’s marked cut points, keeping RGBW sections to a maximum 22 feet and RGBTW sections to a maximum 13.1 feet, with the appropriate power and control connections. Choose a 10- to 12-millimeter channel with a frosted lens, and install tape on the side walls of recessed or in-wall channels when recommended to reduce spotting and create a continuous line of light.
