    One Signal. Minimal Interference.

    Why have a tangle of wireless signals for every light when you could only have one? Together with K-Link cables, the WiFi Dongle controls dozens of lights from one signal. This minimizes wireless interference, leading to a faster, more reliable connection.


    Reliable Reception

    The WiFi Dongle has passed long-term, in-depth field testing and antenna optimization to ensure reliability and efficiency. And with an extension cable, the WiFi Dongle can be easily relocated to the optimal location — perfect for retailers and canopy users.


    Ease of Service

    By keeping the light and its wireless capabilities separate, users can upgrade to the latest WiFi technology without replacing the entire fixture. This modularity also makes it easier to troubleshoot, further saving time and upgrade costs.


    WiFi Controllability

    The app gives users access to advanced manual controls and program customization, as well as the ability to sync groups of lights. Features include full color control, acclimation, lunar cycle, weather effects, and more!
