Active Lighting Splitter Cable — 8-Way Ballast Control

Active Splitter Cable — 8-Way Ballast Control Splitter

An active splitter cable that lets you control up to 8 digital ballasts from a single controller output — ideal for multi-light grow setups where individual ballast control would require 8 separate timer/controller units. Distributes the control signal cleanly to each ballast, keeping lights synchronised across the room.

Why growers choose active splitter cables:

• Controls 8 digital ballasts from one output — major saving on timer/controller hardware
• Active signal distribution — clean signal to each ballast, no voltage drop across the chain
• Keeps lights synchronised — all ballasts switch on/off at the same moment
• Simplifies wiring in multi-light rooms — one controller, one splitter, 8 ballasts
• Works with compatible digital ballasts — check manufacturer compatibility before ordering
• Essential for commercial-scale lighting setups — where individual timer-per-ballast would be impractical

Who it's not for:

Check your ballasts have a control port that accepts this signal format — not all digital ballasts are controller-compatible. For single-light or small setups, direct plug-in timers are simpler. For HyperFan fans or LED drivers, use their specific control cables instead; this is a lighting-ballast splitter, not a universal signal splitter. Magnetic ballasts don't accept signal control; this splitter is for digital ballasts only.
