Growlink Digital Light LINK

Spectrum, Intensity, and Timing on the Growlink Digital lightLINK The Growlink Digital lightLINK runs spectrum, intensity, and timing for any lighting zone wired to the Growlink HUB. The controller talks to compatible fixtures over an RJ-12 data port or a terminal block, depending on the brand. That covers ThinkGrow, Dutch Lighting Innovations, Phantom PX Digital, Synce, Fohse, and other digital-protocol fixtures. Power comes from the HUB over the RJ-45 connection at 24VDC, 1A, 3W typical. One module covers one lighting zone. Larger rooms run one digital lighting controller per zone so each zone holds its own schedule and ramp. Wiring the LINKS Lighting Controller for Sunrise, Sunset, and Safety The controller relies on a canopyLINK and ClimaLINK sensor connected to the HUB for High Heat Shutdown. That's the safety logic that drops the zone if temperature climbs out of range. Sunrise and sunset transitions ramp the lights in over a configurable window at the start and end of each photoperiod. That smooths the stress hit plants take during a hard on/off cycle. Spectrum control adjusts the channel mix on multi-band LEDs through the same digital line. Operating range is 50–122°F and 0–75% RH non-condensing — fits inside any standard control enclosure. The box itself runs 7.75″ × 7.75″ × 3.75″ and ships with a mounting kit, a 10 ft RJ-45 cable, and a screwdriver for the terminal-block wiring. Pair this LINKS lighting controller with Growlink OS to log photoperiod, schedule transitions, and copy proven lighting recipes across rooms. Key Features RJ-12 + Terminal Block Outputs: Talks to compatible fixtures over the digital port their brand uses — no protocol converters needed. Multi-Brand Fixture Support: Works with ThinkGrow, Dutch Lighting Innovations, Phantom PX Digital, Synce, Fohse, and more. Sunrise / Sunset Ramping: Configurable ramp window at the start and end of each photoperiod smooths the plant's transition. Full Spectrum + Intensity Control: Adjusts channel mix on multi-band LEDs and overall intensity from veg through bloom. 24VDC Power via HUB: Pulls 1A, 3W typical over the RJ-45 link — no separate brick at the controller end. High Heat Shutdown Safety: Cuts the zone when canopyLINK or ClimaLINK reports out-of-range temps to the HUB. Mounting Kit + 10 ft RJ-45 Included: Ships ready to install — screwdriver, mounting hardware, and the HUB-to-controller cable in-box.
