Lumatek RJ Ethernet Controller Cable connects controllers and fixtures of the brand via RJ interface for stable communication in indoor growing. Ideal for Lumatek ballasts and LED equipment, it allows centralized control, precise dimming and daisy chain setups with quick and tidy installation.

The Ethernet RJ Lumatek Controller Cable is the data link designed to control LED luminaires (e.g., Zeus and ATS Pro ranges) and electronic ballasts through panels such as the Lumatek Control Panel Plus 2.0. Unlike a power cable, this patch cord transmits control signals via RJ connectors (usually RJ11/RJ14) that fit into “control/link” ports.
The bidirectional communication enables on/off commands, step or continuous dimming (25–100% and even “Super Lumen” mode), timers and routines such as sunrise/sunset; at the same time, it returns equipment statuses and temperature alarms to activate protections.
The construction with copper conductors provides signal integrity; the flexible PVC jacket resists abrasion, ambient humidity, and typical interference near ballasts and extractors.
Available in common lengths (0.5–5 m), it adapts to tents and medium-sized rooms without excess cable.
In scalable projects, the daisy chain format reduces cabling: one run from the panel to the first luminaire and short jumps between the remaining units, which provides order in trays, racks, and technical corridors.
Integrated within indoor electrical accessories, this cable improves the precision of the photoperiod and the uniformity of light on cannabis plants, with less flicker and consistent startups.
For mixed configurations (HPS/LEC + LED) or 100% LED, the fine synchronization of the controller helps optimize PPFD, reduce stress, and stabilize results cycle after cycle.
In indoor growing, a clean control bus makes the difference: fewer cables, fewer errors, and more consistency. With the Ethernet RJ Lumatek Controller Cable, staggered startup, night dimming, progressive sunrise, and temperature safety shutoffs are orchestrated, a solid foundation for tents and rooms focused on performance.
It is used to link the Lumatek control panel with LED grow lights and compatible ballasts, transmitting commands and receiving status data. It also enables daisy chain topologies that organize cabling and speed up expansions, which is key in spaces with several lines or levels.
Accessory with an excellent price-utility ratio: a small investment that enables automation, order, and protection in professional lighting systems, reducing assembly hours and risks from improvised configurations.
Available at Hydroponics Blanes, a trusted Grow Shop and benchmark Grow Shop in Spain, with discreet shipping in 24/48 h. Wide catalog of indoor electrical accessories, Lumatek panels, power strips, and LED grow lights to complete any installation.
Anyone seeking fine control and minimalist cabling will find in the Ethernet RJ Lumatek Controller Cable the ideal bridge between panel and luminaires: precise RJ connectors, stable communication, and “plug & play” installation at the service of cannabis cultivation. At Hydroponics Blanes you will find technical advice, custom packs, and discreet shipping to boost projects with demanding plants and consistent results, season after season.
