Growlink LINKS 4 Channel LightLINK Lighting Controller — 0-10V Outputs Control up to 50 Fixtures Per Channel

Scalable Multi-Zone Lighting Control for Indoor Cultivation with the Growlink LightLINK

The Growlink™ LINKS 4 Channel LightLINK Lighting Controller delivers precise, zone-level dimming control for large-scale indoor growing environments, supporting up to 50 fixtures per channel across four independent 0-10V outputs. Integrated with the Growlink platform, it enables cultivators to manage lighting intensity across multiple grow zones from a single interface — with the ability to schedule, automate, and adjust light levels in response to real-time environmental data.

Built with a rugged, durable construction engineered for demanding cultivation settings, the LightLINK supports optional DIN rail mounting for clean panel installations and operates reliably in high-humidity environments. Made in the USA, it provides commercial cultivators with the flexibility and control needed to optimize lighting programs across diverse grow spaces while maintaining energy efficiency across the entire lighting network.

Key Features & Benefits

• 4 independent channels — control up to four separate lighting zones independently for zone-specific light intensity management.
• 0-10V analog outputs — industry-standard dimming signal compatible with a wide range of 0-10V dimmable horticultural lighting fixtures.
• Up to 50 fixtures per channel — high channel capacity supports large-scale lighting arrays without additional controllers.
• Growlink OS integration — schedule, automate, and adjust lighting across all channels through the Growlink platform for centralized light management.
• Optional DIN rail mounting — supports clean, organized panel installation for professional facility builds.
• Rugged, durable construction — engineered for reliable performance in the high-humidity, high-temperature conditions of active indoor grow environments.
• Made in the USA — built to commercial cultivation standards for long-term professional reliability.

Who Should Use the Growlink 4 Channel LightLINK

The 4 Channel LightLINK is the ideal lighting controller for commercial indoor cultivators running multiple independent lighting zones who need precise, automated dimming control integrated with their broader Growlink automation system. It is particularly suited to operations using 0-10V dimmable fixtures where zone-specific light intensity programming — including photoperiod scheduling and intensity ramping — is essential to crop performance and energy management.

Zone-Level Lighting Management for Precision Indoor Cultivation

Lighting intensity and spectrum management are among the most powerful levers available to indoor cultivators for optimizing yield, quality, and energy efficiency. The LightLINK's four independent channels allow cultivators to program distinct light intensity profiles for different crop stages or zones — ensuring seedlings, vegetative plants, and flowering crops each receive the light levels that maximize their development. Integrated with Growlink's climate and sensor data, lighting can also respond dynamically to environmental conditions such as temperature spikes or VPD excursions, creating a fully coordinated cultivation environment.

Frequently Asked Questions

What dimming standard does the LightLINK use?

The LightLINK uses the 0-10V analog dimming standard, which is the most widely supported dimming protocol among commercial horticultural lighting fixtures. Most professional grow lights with dimming capability include 0-10V compatibility.

How many total fixtures can the 4 Channel LightLINK control?

With up to 50 fixtures per channel across 4 independent channels, the LightLINK can control up to 200 fixtures in total within a single connected system.

Can each channel be programmed with different intensity schedules?

Yes. Each of the four channels operates independently, allowing you to set different dimming levels, schedules, and automation rules for each lighting zone through the Growlink platform.

Does the LightLINK require a Growlink HUB to operate?

The LightLINK integrates with the Growlink LINKS platform. A Growlink HUB or compatible LINKS infrastructure is required to connect the controller to Growlink OS for scheduling, automation, and remote management.

Is DIN rail mounting included with the LightLINK?

DIN rail mounting is optional and supported by the LightLINK. The Growlink LINKS DIN Rail Kit (GLXDINRAILKIT) is available separately for panel installations requiring DIN rail mounting.
