The Lumatek patch cable is designed to connect multiple VF90w or VF120w LED lights together as one circuit to the VF650W LED driver.

Up to 5x VF120w and up to 7x VF90w can be linked to the controller. If you connect a dimmer to the VF650W LED driver, you can control all VF LEDs at the same time. 

With the Lumatek Plus 2.0 digital control panel you have a wide range of settings, for example, you can simulate sunrise and sunset, control the power of the lamps and automatically dim them when it gets too hot in your grow room.
