Growlink LINKS Lighting Adapter — RJ45 Dimmer Adapter for Core Controllers & LINKS Automation Systems

Seamless RJ45 Grow Light Dimming and Control via Growlink Automation

The Growlink™ LINKS Lighting Adapter for RJ45 enables precise, automated control of grow lights equipped with RJ45 dimming interfaces, bridging your lighting fixtures to the Growlink Core Controller or LINKS automation system for centralized, programmable light intensity management. Designed for simple plug-and-play installation, it eliminates the compatibility barrier between RJ45-connected fixtures and the Growlink platform — enabling full lighting automation without additional hardware or complex wiring.

With the RJ45 Lighting Adapter in place, light intensity adjustments, photoperiod scheduling, and automation-driven dimming responses become accessible through Growlink OS. This allows lighting to be coordinated with climate, CO₂, and irrigation systems for a fully integrated cultivation environment where every environmental input responds to the same underlying data and automation rules.

Key Features & Benefits

• RJ45 dimmer compatibility — connects grow lights with RJ45 dimming interfaces directly to Growlink Core Controllers or LINKS automation systems.
• Plug-and-play installation — simple adapter design enables quick, tool-free connection between your fixtures and the Growlink platform.
• Precise light intensity control — enables smooth, accurate dimming of connected fixtures through Growlink OS for stage-specific lighting programs.
• Full Growlink automation integration — lighting becomes part of your broader Growlink automation workflow, responding to schedules, sensor data, and manual overrides.
• Compatible with Growlink Core Controllers and LINKS systems — works with both Growlink's Core Controller lineup and the LINKS automation platform.
• Supports photoperiod and intensity scheduling — program light-on/off timing and intensity ramps through Growlink OS for optimized growth cycle management.

Who Should Use the Growlink RJ45 Lighting Adapter

The RJ45 Lighting Adapter is essential for cultivators using grow light fixtures with RJ45 dimming interfaces who want to bring those fixtures under Growlink automation control. It is particularly valuable in operations transitioning to centralized Growlink management where existing RJ45-equipped fixtures need to be integrated without replacement, and for facilities building out new automation systems around a mix of fixture brands and connection types.

Integrating Lighting into a Unified Cultivation Automation System

Lighting control becomes significantly more powerful when it operates as part of a coordinated automation system rather than independently. Through the Growlink platform, the RJ45 Lighting Adapter enables lighting responses that are synchronized with temperature, humidity, VPD, and CO₂ data — for example, automatically dimming lights when canopy temperatures rise, or adjusting intensity based on DLI targets tracked through ClimaLINK PPFD data. This level of integration elevates lighting from a fixed schedule to a dynamic, responsive component of a precision cultivation environment.

Frequently Asked Questions

What grow light fixtures are compatible with the RJ45 Lighting Adapter?

The RJ45 Lighting Adapter is compatible with grow light fixtures that use an RJ45 interface for dimming control. Check your fixture's specification sheet for RJ45 dimming compatibility before purchasing.

What is the difference between the RJ45 and RJ12 Lighting Adapters?

The RJ45 and RJ12 Lighting Adapters are functionally identical — both enable grow light dimming control through the Growlink platform — but are designed for different connector types. The RJ45 adapter is for fixtures using the larger 8-position RJ45 connector, while the RJ12 adapter (GLXRJ12ADAPT) is for fixtures using the smaller 6-position RJ12 connector. Choose the adapter that matches your fixture's dimming interface.

Does this adapter work with Growlink LINKS systems as well as Core Controllers?

Yes. The Growlink RJ45 Lighting Adapter is compatible with both Growlink Core Controllers and the LINKS automation system, providing flexibility across different Growlink platform configurations.

Can I use this adapter to schedule light-on and light-off times?

Yes. Once connected through the Growlink platform, the adapter enables full photoperiod scheduling — including light-on/off timing, intensity ramps, and automation-driven responses — through Growlink OS.

Is any additional hardware required to use this adapter?

No additional hardware is required beyond a compatible Growlink Core Controller or LINKS system. The adapter connects directly between your RJ45-equipped fixture and the Growlink controller for immediate integration.
