Have one of our fiber optic kits installed but want multi-zone functionality? This is the upgrade for you! Thanks to our intuitive app design, adding an additional XKchrome Controller (Zone) couldn’t be easier. Simply pair the new controller, group your controllers together to sync up or keep them separate for ultimate customization. For use with our 5V Fiber Optic LED Heads only. Feel free to check out our other XKchrome Controllers for use with your 12V lighting accessories.
