Built for both commercial facilities and serious craft growers, Digital LightLINK makes advanced lighting automation accessible, scalable, and repeatable. Key Features Full Spectrum ControlPrecisely adjust light intensity and spectrum to match each growth stage. Automated Sunrise and SunsetGradual lighting transitions reduce plant stress and promote more natural growth behaviour. Wide Brand CompatibilityWorks with ThinkGrow, Dutch Lighting Innovations, Phantom, Syncro, Fohse, and many other major lighting manufacturers. Growlink OS IntegrationConnects seamlessly to Growlink OS for remote access, automation, data tracking, and AI-driven lighting recipes. Built for Real Grow EnvironmentsDesigned and manufactured in the USA for reliability in demanding indoor and greenhouse conditions. Why Growers Choose Digital LightLINK Manual timers and basic dimmers cannot deliver the precision modern growers need. Digital LightLINK removes guesswork by standardising light schedules, spectrum output, and transitions across your entire facility. When connected to Growlink OS, growers can monitor lighting performance in real time, automate adjustments, and replicate proven strategies across multiple rooms or sites. Trusted by thousands of growers worldwide, Growlink technology is built for consistency, efficiency, and scale.

Take full control of your lighting strategy with Growlink Digital LightLINK and build a smarter, more consistent grow from day one. 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. Digital lightLINK handles precision lighting control — spectrum, intensity, and sunrise/sunset simulation — connecting into Growlink OS for automated lighting recipes across every room. 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.
