OEM 10ft pigtail cord matched to 277–480V commercial service for Flexstar UCL fixtures.
The Flexstar 277–480V UCL Pigtail Power Cord (10ft) is the correct OEM power cord for Flexstar under-canopy LED fixtures installed on high-voltage commercial service. Open-end pigtail termination is designed for hardwire connection to a junction box or panel — the appropriate choice for 277V single-phase or 480V three-phase commercial infrastructure.
Flexstar UCL under-canopy fixtures are designed to operate across a wide input voltage range. The standard cord shipped with many UCL kits is configured for 120V or 240V service. For facilities running 277V single-phase or 480V three-phase distribution — common in purpose-built commercial cultivation buildings, converted industrial spaces, and large-scale multi-tier vertical grows — a separate, voltage-matched cord is required. This is that cord.
The pigtail (open-end) termination means the cord does not terminate in a standard NEMA plug. Instead, the conductors are left exposed for direct hardwire connection into a junction box, disconnect, or panel. This is standard practice in commercial electrical installations where fixtures are permanently mounted and circuits are dedicated — not plug-and-play. Installation must be performed by a licensed electrician per local code.
If your facility's lighting circuits run on 277V (the phase-to-neutral voltage of a 480V/277V wye distribution system, standard in most commercial and industrial buildings in the US), this is the cord your Flexstar UCL fixtures require. Plugging a fixture rated for this service into a 120V or 240V cord — or vice versa — creates a mismatch that can damage the driver or create a safety hazard.
The 480V rating also covers use cases where fixtures are wired directly into a 480V circuit in an appropriate configuration. Large licensed cannabis cultivators and hemp production facilities that spec commercial-grade electrical infrastructure from the ground up routinely operate at these voltages to reduce wire gauge requirements and improve distribution efficiency across large canopy footprints. This cord is the OEM-matched solution for those builds — not an aftermarket substitute.
This cord is purpose-built for the Flexstar UCL under-canopy LED line — the same fixtures used in commercial cannabis and hemp grows for supplemental lower-canopy illumination. Flexstar UCL fixtures support daisy-chain runs of up to 17 units from a single feed point, with 0–10V dimming via RJ11 and IP66-rated weatherproof construction. Matching the power cord to your service voltage is a prerequisite for proper driver operation and to maintain the fixture's ETL/DLC/CE certification compliance.
At 277V service, each UCL 120W fixture draws approximately 0.43A — significantly lower current per fixture than 120V operation (1.0A). This matters when calculating circuit loading for a daisy-chain run or a full room deployment. The 10-foot length provides practical reach from a ceiling junction box or wire drop to the fixture mounting position without creating excess slack that needs to be managed in a wet, IP-rated environment.
If you're speccing a new under-canopy lighting installation or retrofitting an existing room onto high-voltage service, confirm your panel voltage before ordering. Facilities on 208V/120V service need the 240V cord; facilities on 480V/277V service — the majority of newer commercial cannabis builds — need this 277–480V variant. Ordering the wrong cord at scale means delays and a return process before your install crew can go live.

The standard UCL cord is configured for lower-voltage service (120V or 240V). This 277–480V variant is built for commercial facilities running high-voltage distribution — typically 480V/277V wye systems common in industrial and purpose-built cultivation buildings. Using a voltage-mismatched cord can damage the fixture driver and voids certification compliance.
At 277V and 480V, permanently hardwired connections to a junction box or dedicated circuit are standard practice in commercial electrical installations. Pigtail termination is designed for this — a licensed electrician makes the final connection at the panel or junction box. There is no standard NEMA wall-plug rated for this voltage range in a horticultural fixture context.
If your building's main distribution panel is a 480V/277V wye system (common in commercial and industrial construction in the US), your lighting circuits will be 277V phase-to-neutral. Your electrical contractor or facility drawings will confirm this. If you're on a 208V/120V system, you need the 240V UCL cord variant instead.
Each Flexstar UCL 120W fixture draws approximately 0.43A at 277V. On a 20A dedicated circuit, you can load up to 16 fixtures at 80% NEC capacity (16A), which aligns closely with the fixture's 17-unit daisy-chain limit. Always confirm circuit loading calculations with your licensed electrician before finalizing your layout.
