Infinite Range and Instant Response  

Thanks to our patented Bi-flow technology, once the controller is on your home Wi-Fi network, distance and signal stability won’t slow you down. Walls, floors, and yards won’t get in the way—your ground lights react the moment you tap.

One-Step Group Setup  

Ditch the hassle of pairing each fixture. Simply link your phone to the Alter-Link controller, make sure only your low voltage landscape lights share that circuit, and you’re set. Use the built-in Pause/Sync button on any fixture to assign individual colors or sync the whole group in seconds.

AC 12–15V Safe Low Voltage  

Operating on a gentle 12 to 15 volts AC, these in-ground lights meet UL 1838 safety standards and play nicely with standard low-voltage connectors and accessories. Robust and reliable, they’re engineered for outdoor use and flexible installation.

Wireless Control and Voice Commands  

Hook up to 2.4 GHz Wi-Fi, then control your lighting from anywhere with the Smart Life app. Prefer hands-free? Just say “Alexa” or “Hey Google” to adjust colors, brightness, or scenes. Crank up Music Mode or choose from preset lighting shows for instant atmosphere.

Endless Colors and Year-Round Ambiance 

Whether you want the soft glow of candlelight at 1800K or a crisp white at 5000K, these fixtures have you covered. With 16 million colors, 16 scene modes, and tuning from warm to cool, you can create daily accents or celebrate every season in style.

NOTE

1. Use only Alter-Link series fixtures with the Bi-Flow Controller. Connecting any other brand or series can damage both the controller and your lights.  

2. The Bi-Flow Controller supports a maximum load of 120W. Verify that the combined wattage of all attached fixtures remains below 120W.  

3. A separate extra-low-voltage transformer is required but not included—please purchase one independently.
