The Growlink digital lightLINK (GL-LINK-LIGHTD) is a digital lighting control module that bridges the Growlink LINKS HUB to compatible fixtures from nine supported manufacturers, delivering full intensity and spectrum control via RJ-12 or hardwired terminal block connections. One module is deployed per lighting zone, giving licensed commercial cultivators precise, automated light management across every room in the facility.

• Origin: Made in USA
• Installation: Mount outside the direct growing area, above the canopy and away from drip zones, misters, foggers, and humidifiers
• High-Humidity Installation: Weatherproof enclosure recommended where continuous RH exceeds 70%
• 0–10V Compatibility: No — 0–10V-only fixtures should use the Growlink 4-channel lightLINK instead
Key Advantage: The digital lightLINK provides a true digital lighting-control bridge rather than simple 0–10V dimming, allowing compatible fixtures to receive centralized intensity, spectrum, scheduling, ramping, and sensor-driven control through Growlink OS. Its one-zone-per-module architecture also makes multi-room systems straightforward to scale.
