The 4 channel lightLINK connects Growlink’s intelligent controllers to 0–10V devices for light dimming, fan speed control, VSD/VFD drives, and miscellaneous 0–10V control. Four independent analog output channels each drive up to 50 fixtures, delivering scalable, zone-based control across your growing environment.

Without precise dimming control, growers waste energy and risk inconsistent canopy light levels. The 4 channel lightLINK delivers independent 0-10V dimming across four zones for optimized light intensity, better yields, and lower energy costs.
Run four separate lighting zones from a single device.
Analog dimming for precise intensity control on each channel.
Scale up to 200 fixtures total across four zones.
Works with dimmable ballasts, VFD motor controllers, and other 0–10V equipment.
Professional installation with standard DIN rail mounting.
Engineered for greenhouse and indoor cultivation environments.
The 4 channel lightLINK connects to the LINKS HUB — joining climate, irrigation, substrate, and nutrient devices into a single automated system managed through Growlink OS.
Multi-zone facilities needing independent dimming control across flower and veg rooms.
Supplemental lighting control with scheduling and intensity management for greenhouse crops.
Precise light recipes across multiple rack zones with energy-efficient dimming.

The central brain of your automated grow operation. Connect and power up to eight LINK devices.

Real-time canopy-level temperature and humidity monitoring with built-in PAR sensor.

Precision climate monitoring for temperature, humidity, CO2, and VPD.

Versatile relay control for HVAC, humidifiers, dehumidifiers, and other mixed-voltage equipment.
