Description
Zone-specific lighting made simple.
The Growlink LINKS 4 Channel lightLINK gives you precise 0–10V analog dimming control across four independent lighting zones. Each channel drives up to 50 fixtures, making it easy to standardise lighting intensity across multiple rooms while keeping every zone controllable on its own schedule.
Whether you're running LEDs, ballasts, or a mixed lighting setup, 4 Channel lightLINK brings centralised, repeatable dimming control into Growlink OS — cutting energy waste and keeping every zone consistent from propagation through flower.
Key Features
- Four Independent 0–10V Channels: Control up to 50 fixtures per channel across four separate lighting zones.
- Flexible Analog Dimming: Smooth intensity adjustment for every growth stage, from propagation to flowering.
- Wide Compatibility: Works with leading grow light brands including Gavita, Fluence, TrolMaster, and more.
- Growlink OS Integration: Automate sunrise/sunset ramping and set lighting recipes per room from one dashboard.
- Rugged, Reliable Build: Engineered for greenhouse and indoor environments, with optional DIN rail mounting.
Why Growers Choose 4 Channel lightLINK
Manual dimmers and standalone timers can't standardise lighting across multiple zones. 4 Channel lightLINK brings centralised, analog dimming control to every room, reducing human error and giving you the same repeatable lighting strategy wherever it's deployed.
Trusted by thousands of professional cultivators worldwide, Growlink lighting hardware is built for reliability, scalability, and long-term performance.

Part of the Growlink LINKS Ecosystem
LINKS is Growlink's modular grow-room hardware system: small, purpose-built devices that each do one job well, and click together into a whole-facility control network. 4 Channel lightLINK drives up to four independent 0–10V dimming zones, standardising lighting control across multiple rooms through Growlink OS. Every LINKS device can run wirelessly on its own over Wi-Fi, but connecting to the HUB over a wired RJ-45 connection unlocks whole-room automation, longer signal range, and the ability for the HUB to power and enable additional LINKS hardware across the facility.

"Run cultivation from a system that learns."
Every 4 Channel lightLINK connects into Growlink OS, the cultivation management portal that turns your best irrigation practices into living Blueprints — standardised schedules and automation logic you can roll out across every room. Growlink OS includes Nova, Growlink's built-in AI, which compares performance across rooms, flags deviations from plan, and answers questions about crop performance without you having to dig through spreadsheets.
