Each controller can control up to 4 zones separately or simultaneously with an RF receiver in each zone. 3 configurations (color & intensity) can be saved for each zone. Buttons also allow for quick access to 25%, 50%, 75%, and 100% light intensity. Can be stably put on magnetic wall mount to function as a light switch, or taken with a user for easier access.
