Flexstar 277V 10ft right-angle M19 power cord

What This Cord Is

This is the OEM-matched power input cord for Flexstar LED fixtures operating on 277V single-phase commercial service — the voltage delivered by one hot leg of a 480V three-phase panel, standard in commercial and industrial cultivation facilities built to NEC commercial electrical codes.

The M19 connector is a 3-pin locking-style connector used across Flexstar's commercial LED fixture line to connect the power supply enclosure (driver/ballast) to the mains feed. The right-angle configuration at the M19 end keeps the connection low-profile and directs cable routing parallel to the fixture, reducing strain on the connector body in overhead or rack-mounted installs.

At 10 feet, the cord provides enough reach for most fixture-to-breaker or fixture-to-PDU runs in standard bay spacing without requiring an extension. If your run is longer, a separate extension cord rated for 277V and M19 termination is required — do not daisy-chain standard cords to gain length.

Who Needs This Cord

This cord is a fit for any licensed cannabis or hemp cultivation operator running Flexstar LED fixtures on 277V service. Facilities built with 480V three-phase electrical infrastructure typically distribute 277V single-phase to individual lighting circuits — it is the most common service voltage in purpose-built commercial grow rooms, warehouses converted for cultivation, and multi-tier vertical farms.

You need this specific cord if: (1) your facility's lighting circuits are wired for 277V, (2) your Flexstar fixtures use the M19 input connector, and (3) your existing cord is damaged, missing, or you are expanding your fixture count and need additional cords to complete the install. Running the wrong voltage cord on a 277V circuit is a safety and equipment-damage risk — confirm your panel voltage before ordering.

This cord is not a universal adapter. It is voltage-specific and connector-specific. If your facility runs 120V, 208V, or 240V service, a different Flexstar cord SKU applies to your configuration.

Installation and Wiring Considerations

277V is a line-to-neutral voltage derived from a 480Y/277V wye-configured three-phase service. It requires a dedicated 277V circuit with a correctly rated breaker — typically a single-pole breaker in a 480V panel. Do not attempt to connect this cord to a 120V or 240V outlet; the voltage ratings are not interchangeable.

The M19 connector mates directly to the M19 female outlet on the Flexstar power supply enclosure. Seat the connector fully and verify the lock engages before energizing. The right-angle exit keeps the cord profile tight against the fixture body, which matters in overhead installations where cable sag or tension on the connector can work connections loose over time.

For multi-fixture rows, verify whether your Flexstar configuration supports daisy-chaining via the M19 port or requires a homerun cord to each fixture. Consult the fixture-specific installation manual or contact HSC for configuration guidance before finalizing your cord count.

Ordering for a Commercial Build

Facilities deploying Flexstar LEDs at scale should order cords at the same time as fixtures. Cord count equals fixture count — one cord per fixture unless your specific fixture model supports a daisy-chain topology that reduces the homerun cord count. Having spare cords on-site eliminates downtime if a cord is damaged during installation or routine maintenance.

If you are commissioning a new room or expanding canopy, confirm your panel voltage and fixture input spec with your electrical contractor before placing the cord order. Flexstar fixtures accept multiple input voltages (120V, 208V, 240V, 277V), and each voltage requires its own cord SKU. Mixing cord voltages is a code and safety violation.
