One control signal across the entire row — M12 twist-lock, moisture-rated, plug-and-play.
Flexstar M12 Daisy Chain Cable (A3) – 10ft links compatible Flexstar LED fixtures in series so a single controller signal drives the entire run. The A3 3-pin configuration is designed for fixed-spectrum Flexstar fixtures; the M12 twist-lock connectors seat mechanically at both ends — no tools, no crimping, no mid-run dropouts.
The Flexstar M12 Daisy Chain Cable A3 is a purpose-built fixture-to-fixture control cable for compatible Flexstar LED grow light systems. It carries the 0-10V dimming signal from one fixture's control output to the next fixture's control input, extending a single control run down an entire row without requiring individual controller connections to each fixture.
The A3 designation identifies the 3-pin wiring configuration used on fixed-spectrum Flexstar LED models. This is a distinct configuration from the A4 (4-pin) variant — using the wrong cable for the wrong port will result in an incomplete or non-functional chain. Verify your fixture's control port spec before ordering. The 10ft length is engineered for typical overhead fixture spacing in commercial grow rooms where fixtures are mounted close together along the same bay or row.
This cable is a required accessory for any licensed cannabis or hemp operator running multiple Flexstar LED fixtures on a shared controller — whether that's a Flexstar Zeus controller, a 0-10V compatible environmental controller, or any other compatible dimming interface. Without a daisy-chain cable, each fixture in the row needs its own controller connection, which adds cost, cable clutter, and control complexity.
This cable is particularly relevant for commercial vertical farms, multi-tier rack systems, and large flat-canopy rooms where multiple Flexstar fixtures are hung in line along a single bay. Rather than running individual control drops to every fixture, operators use the daisy-chain run to keep wiring clean, reduce installation time, and ensure consistent dimming signal across every light in the row.
M12 twist-lock connectors on both ends seat and lock mechanically rather than relying on friction or a simple push-fit. In an active grow environment — where vibration from HVAC equipment, foot traffic on raised platforms, or an accidental cable pull is routine — a twist-lock connection stays seated where a push-fit plug would eventually work loose and interrupt the control signal mid-run.
The cable's moisture-resistant construction handles the condensation cycles, high ambient humidity, and occasional spray exposure common in commercial cannabis and hemp facilities. Standard cable materials degrade in these conditions over time; a rated cable holds up across continuous operation without jacket breakdown or connector corrosion that would compromise signal integrity.
Installation is plug-and-play: connect the male M12 end to the signal output port of one fixture, connect the female M12 end to the signal input port of the next fixture, and repeat down the line. No crimping tools, no adapters, no configuration — the chain is live as soon as the controller is set.
In a commercial build, lighting control wiring is frequently an afterthought until the fixture installation is underway. Plan your control cable count at the same time you spec your fixture count: one daisy-chain cable bridges every adjacent fixture pair in each row. A row of ten fixtures requires nine cables. For rows where fixtures are spaced tightly — standard in vertical rack configurations or dense overhead arrays — the 10ft length handles most spans without excess slack that becomes a housekeeping issue.
Flexstar's LED lineup supports daisy-chain runs of up to 17 fixtures in seamless end-to-end configuration, giving you the flexibility to control a significant portion of a commercial room's fixtures from a single controller channel. Building in the correct A3 daisy-chain cables from the start keeps your control wiring clean, your channels consolidated, and your lighting system straightforward to adjust, troubleshoot, or expand.

The A3 uses a 3-pin connector configuration and is designed for fixed-spectrum Flexstar LED fixtures. The A4 uses a 4-pin configuration for fixture connection points that require the A4 interface. They are not interchangeable — using the wrong cable for the wrong port will result in an incomplete or non-functional control connection. Check your fixture's control port specification before selecting a cable.
Flexstar's LED systems support daisy-chain runs of up to 17 fixtures in a seamless end-to-end configuration. For larger installations, consult your controller's specifications to confirm how many channels and fixtures it can manage simultaneously.
The daisy-chain cable carries a 0-10V dimming signal between fixtures. Compatibility with a third-party controller depends on whether that controller outputs a standard 0-10V signal and uses an M12-compatible interface or an adapter. Confirm your controller's output type and connection spec before assuming compatibility — Flexstar fixtures are validated against the Flexstar Zeus controller line.
The 10ft length suits tight overhead configurations where Flexstar fixtures are mounted close together along the same bay — typical in vertical rack builds or dense canopy arrays. If your fixture spacing is wider, or if you're running a longer span between fixtures, a 15ft variant may be more appropriate. Measure your fixture center-to-center spacing and add routing slack before committing to a cable length.
One cable bridges each adjacent fixture pair in the chain. In a row of ten fixtures, you need nine daisy-chain cables — one connecting fixture 1 to 2, another connecting 2 to 3, and so on down the line. Plan your cable count at the same time you plan your fixture layout.
