To size a 24V power supply for a linear lighting run, multiply the tape’s wattage per foot by the total run length, then account for the control module and a reasonable capacity margin. Choose a 24V DC constant-voltage supply rated above the calculated load, and divide longer or higher-wattage installations across multiple supplies when needed.

24V linear lighting supports forward- and reverse-phase dimming, including ELV, MLV, and TRIAC control, through a compatible 24V power supply and dimmer. For networked control, DMX uses a lighting gateway and decoder, while Zigbee uses a compatible five-channel control module for dimming, color changes, and tunable-white adjustment.

Supported 24V linear lighting tape can be cut at marked intervals, with some versions cuttable every 3.94 inches and limited to a 20-foot maximum run, so plan each section before cutting and match any extension to the tape’s voltage, polarity, and control method. Install the tape on a clean surface or in a compatible extrusion with a diffuser, then use a properly sized 24V DC constant-voltage power supply and the appropriate dimmer, DMX decoder, or Zigbee control module.

RGBW 24V linear lighting combines red, green, and blue color mixing with a dedicated warm-white channel, while RGB tunable white adds adjustable white color temperature alongside RGB colors. Fully tunable white provides adjustable white light from a warm glow to daylight without RGB color mixing, making it suited to projects focused on white-light control rather than color effects.
