Gavita Interconnect Cable – 5 ft

The Gavita Interconnect Cable – 5 ft is a dedicated signal cable for Gavita E-series ballast systems. It carries the controller signal between ballasts in a daisy-chain arrangement, allowing a single Gavita Master Controller to manage multiple ballasts together. The 5 ft length suits most standard ballast rack configurations, and the cable is also available in 2 ft, 8 ft, and 10 ft versions to match different room layouts.

Why Choose the Gavita Interconnect Cable – 5 ft

Gavita E-series ballasts are designed to operate as a networked system rather than as independent units. The interconnect cable is the physical link that makes that coordination possible. Without it, each ballast operates on its own schedule — with it, every ballast on the daisy chain responds to the Master Controller’s commands simultaneously.

The 5 ft length is the most practical choice for rooms where ballasts are mounted in a row or on a horizontal rail with moderate spacing. It provides enough reach to connect adjacent units without creating a loop of excess cable that has to be managed around the canopy. Growers who need longer runs between ballasts can select the 8 ft or 10 ft versions; those with closely spaced units can use the 2 ft version instead.

• Daisy-chain signaling: Passes the controller signal from one E-series ballast to the next, enabling centralized scheduling and dimming from a single Gavita Master Controller.
• Purpose-built for E-series: Engineered specifically for Gavita E-series ballasts — uses the correct connector and signal protocol for reliable communication.
• Multiple length options: The 5 ft cable is part of a family (2, 5, 8, and 10 ft) so you can select the length that minimizes cable management complexity for your specific rack spacing.
• Lightweight: At 0.0639 lb, the cable adds negligible weight to an overhead ballast installation.

Best Uses for the Gavita Interconnect Cable – 5 ft

This cable is specifically for growers who run Gavita E-series ballasts controlled by a Gavita Master Controller. Common installation scenarios where the 5 ft version is the right choice:

• Standard horizontal rails: When E-series ballasts are mounted on a horizontal rail with roughly 3–5 ft of spacing between units, the 5 ft cable provides a clean connection without excess slack.
• Expanding an existing daisy chain: If you are adding one or two ballasts to an already-controlled group, the 5 ft cable is a practical all-around length for extending the chain.
• Rooms with centralized controller placement: Works well when the Gavita Master Controller is mounted near the center of a row and ballasts are arranged at uniform spacing in both directions.
• Commercial and hobby grow rooms: Suitable for any scale of E-series installation where a single Master Controller manages multiple ballasts — from a 4-light hobby tent up to a multi-light commercial room.
• Replacement cabling: Replaces a damaged or missing interconnect cable in an existing Gavita E-series installation without requiring new ballasts or a new controller.

If you are building a full Gavita E-series lighting system, you may also want to look at compatible HPS grow light bulbs for your fixtures, or a grow tent to house your setup.

Compatibility

The Gavita Interconnect Cable – 5 ft is designed for use with Gavita E-series ballasts in combination with a Gavita Master Controller. The cable carries the controller signal between consecutive ballasts in a daisy-chain topology — one cable runs from the signal output of the first ballast to the signal input of the next, and so on down the chain.

This cable is not a power cable and is not interchangeable with the Gavita 8 ft or 120V power cords used to supply mains voltage to the ballasts. It is specifically the low-voltage signal cable that enables the Master Controller to communicate with and adjust each ballast individually or as a group.

If your E-series ballasts are currently uncontrolled (running at fixed output), adding a Gavita Master Controller and a set of these interconnect cables allows you to implement scheduled dimming, gradual sunrise/sunset cycles, and remote output adjustment across all connected units simultaneously. The number of cables required equals the number of ballasts in the chain minus one (for example, four ballasts require three interconnect cables).
