{"product_id":"growlink-4-channel-lightlink","title":"Growlink 4-Channel lightLINK","description":"\u003cp\u003eThe Growlink 4-Channel lightLINK (GL-LINK-LIGHT4) is an analog lighting-zone controller for commercial and advanced cultivation environments. It provides four independent 0–10V outputs, allowing up to 50 dimmable fixtures per channel (200 total) to be controlled independently. Connected to the Growlink LINKS HUB and Growlink OS, it enables centralized scheduling, intensity control, sunrise\/sunset ramping, and remote management of compatible 0–10V lighting systems.\u003c\/p\u003e\n\n\u003cp\u003e• SKU: GL-LINK-LIGHT4\u003cbr\u003e\n• Manufacturer: Growlink\u003cbr\u003e\n• Product Line: LINKS Ecosystem\u003cbr\u003e\n• Output Type: 4 × independent 0–10V analog outputs\u003cbr\u003e\n• Fixture Capacity: Up to 50 fixtures per channel \/ 200 fixtures total\u003cbr\u003e\n• Input Power: 24V DC via LINKS HUB\u003cbr\u003e\n• Output Current: 0.125 mA per channel maximum; 0.5A total maximum\u003cbr\u003e\n• Compatible Fixtures: 0–10V dimmable LED drivers and dimmable HPS ballasts\u003cbr\u003e\n• Other Compatible Devices: Variable-speed drives and other analog voltage-controlled devices\u003cbr\u003e\n• Independent Zones: 4 fully independent lighting zones\u003cbr\u003e\n• Independent Dimming: Each channel can operate at a different intensity\u003cbr\u003e\n• Independent Scheduling: Separate photoperiod, intensity, and sunrise\/sunset ramp profiles for each zone\u003cbr\u003e\n• Growlink OS Integration: Centralized lighting automation and recipe control\u003cbr\u003e\n• Remote Control: Growlink OS \/ Growlink App\u003cbr\u003e\n• HUB Requirement: Growlink LINKS HUB required and sold separately\u003cbr\u003e\n• HUB Port Usage: Occupies 1 of the HUB's 8 device ports\u003cbr\u003e\n• System Expansion: Additional 4-Channel lightLINK modules can be added to the same HUB, subject to the HUB's 8-port limit\u003cbr\u003e\n• Digital Lighting Compatibility: For fixtures using proprietary digital protocols, Growlink's digital lightLINK is the appropriate module; analog and digital lightLINK modules can coexist on the same HUB\u003cbr\u003e\n• Mounting: Wall mount with hardware included\u003cbr\u003e\n• DIN Rail: Optional DIN rail mounting kit, sold separately\u003cbr\u003e\n• Country of Origin: Made in USA\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The 4-Channel lightLINK provides four genuinely independent 0–10V lighting zones, so different rooms or crop areas can run different intensities, photoperiods, and ramp profiles simultaneously. With capacity for up to 200 fixtures per module, it offers a scalable way to bring conventional 0–10V lighting into the Growlink OS automation platform.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610195099684,"sku":"GL-LINK-LIGHT4","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/4-channel-lightlink-gl-link-light4.jpg?v=1791317766","url":"https:\/\/www.growitdepot.com\/products\/growlink-4-channel-lightlink","provider":"Grow It Depot","version":"1.0","type":"link"}
