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

Bring RJ45 Dimmable Fixtures Under Growlink OS Control

Grow light fixtures that dim through an RJ45 interface don't automatically speak the same language as a Growlink automation system, and the Growlink LINKS Lighting Adapter for RJ45 closes that gap. It bridges an RJ45-equipped fixture directly to a Growlink Core Controller or LINKS system, so intensity control, photoperiod scheduling, and automated dimming responses all become reachable through Growlink OS instead of a fixture-specific remote or app.

The 8-position RJ45 connector plugs in without rewiring, and once connected, lighting can be coordinated with temperature, humidity, and CO2 data already flowing through the same Growlink account — for example dimming automatically when canopy temperature climbs.

Key Features & Benefits

• RJ45 Dimmer Compatibility: Connects fixtures using the 8-position RJ45 dimming interface to Growlink Core Controllers or LINKS systems.
• Plug-and-Play Installation: No rewiring or splicing required between the fixture and the Growlink controller.
• Full Intensity Control: Enables smooth dimming and stage-specific lighting programs through Growlink OS.
• Photoperiod Scheduling: Program light-on and light-off timing alongside intensity ramps from the same interface.
• Coordinated Automation: Lighting responses can be tied to temperature, humidity, and CO2 data already in your Growlink account.

Who Should Use This

Cultivators running RJ45-equipped grow light fixtures who want those fixtures under centralized Growlink control, rather than a separate fixture-specific dimmer or app, are the direct fit for this adapter.

About Growlink

Since its founding in 2015, Growlink has extended its Growlink OS lighting automation to a broad range of third-party fixture dimming interfaces through purpose-built adapter hardware.

Frequently Asked Questions

How do I know if my fixture uses an RJ45 dimming interface?

Check your fixture's specification sheet or the physical connector on the driver for a 8-position jack. If your fixture instead uses the RJ12 connector, the corresponding adapter (GLXRJ12ADAPT) is the correct match rather than this one.

What is the difference between the RJ45 and RJ12 adapters?

Both adapters provide identical Growlink dimming functionality; they differ only in the physical connector each is built for. Choose the adapter matching your fixture's dimming jack rather than assuming either will fit.

Does this adapter work with both Core Controllers and LINKS systems?

Yes, it is compatible with both the Growlink Core Controller lineup and the LINKS automation platform, giving flexibility across different Growlink configurations. This means the same adapter part can move between a Core Controller deployment and a LINKS deployment without needing a different SKU.

Can I schedule sunrise and sunset ramps through this adapter?

Yes, once connected, the adapter supports full photoperiod scheduling including intensity ramps, through the same Growlink OS interface used for other automation. Ramp duration and curve are configurable rather than fixed, so the transition can be tuned to your specific fixture and photoperiod.
