Growlink Digital LightLINK Grow Light Controller

Precision Light Control, Room After Room

Digital LightLINK gives real control over light intensity and timing without a spaghetti of timers. It delivers accurate intensity control and smooth transitions across LED, HPS and mixed lighting systems, and connects to Growlink OS for remote access, data tracking and automated lighting recipes. Automated sunrise and sunset ramps lights gradually rather than slamming them on, and it works with a wide range of major lighting manufacturers. Powered by 24V DC via the Growlink HUB at roughly 3W, it is made in the USA for demanding indoor and greenhouse conditions.

Key Benefits

• Accurate intensity control so each growth stage gets the light level it needs
• Automated sunrise and sunset ramping reduces stress at lights-on and lights-off
• Broad compatibility via terminal block and RJ-12 outputs
• Growlink OS integration for remote monitoring, scheduling and repeatable recipes
• Low draw of around 3W at 1A, running on 24V DC from the HUB
• Built for real rooms, rated 10°C to 50°C and up to 75% RH non-condensing

Guesswork Schedules and Stressed Plants

Mechanical timers and basic dimmers give you on or off and little else. Plants hit with full intensity from cold show stress, excessive stretch early in flower and inconsistent results between rooms running the same genetics. LightLINK standardises schedules, ramps and output across every fixture and logs what actually happened. Once a strategy works you replicate it exactly, and lights stop running harder than the canopy can use.

How to Use

• Mount the controller using the supplied mounting kit
• Connect to the Growlink HUB with the 10ft RJ-45 cable for power and data
• Wire fixtures to the terminal block or RJ-12 data port to suit your lighting brand
• Set intensity targets and photoperiod per room in Growlink OS
• Enable sunrise and sunset ramps to soften daily transitions
• Keep the unit within 10°C to 50°C and 0 to 75% RH non-condensing
