OEM-matched 277V input cord for Flexstar LED fixtures — straight M19, 10ft run.
The Flexstar 277V 10ft Straight M19 Power Cord (SKU 10-010704-260) is the correct input power cable for Flexstar LED fixtures operating on 277V commercial electrical service. Match the cord to your facility's service voltage and the M19 connector on your fixture — mismatched cords are one of the most common causes of installation delays and nuisance trips on new builds.
This is the OEM-spec input power cord for Flexstar LED fixtures wired to 277V single-phase commercial electrical service. Flexstar's LED line — including the PRO 645W, 720W SE, 800W, and 1000W fixtures — uses an M19 3-pin industrial connector as the power input interface on the fixture's power supply enclosure. This cord terminates in a female M19 connector on the fixture end and a service-side plug matched to 277V circuits on the supply end.
The straight configuration (as opposed to a daisy-chain or right-angle variant) positions this cord as the primary input run from a circuit outlet or distribution whip to the fixture. At 10 feet, it provides enough slack for standard overhead mounting configurations without creating excess cord management issues at the fixture end.
277V is the standard single-phase voltage derived from a 480V/277V wye distribution system — the electrical infrastructure found in most purpose-built commercial cultivation facilities, warehouses converted to grow space, and any building served by a 480V three-phase panel. If your facility runs 277V circuits to your lighting panels, this is the cord your Flexstar fixtures require. Running a 120V or 240V cord on a 277V circuit — or vice versa — is a code violation and a fire risk.
This cord is also the right part to have on hand for expansion builds, new room fit-outs, or replacing a damaged input cord on an existing fixture. On a canopy of 50–200+ fixtures, having the correct replacement cord in inventory avoids the kind of single-point downtime that pushes a harvest day. It's a low-cost line item that belongs in every licensed operator's maintenance kit if the facility is running Flexstar fixtures on 277V service.
The M19 is an industrial-grade circular connector used across Flexstar's commercial fixture line for power input. Per Flexstar's own installation documentation, the correct procedure is to connect the M19 female connector on the power cable to the male connector on the fixture's power supply enclosure — and critically, to never connect or disconnect the fixture under load. The M19 format provides a secure, positive-lock mating that resists vibration and accidental disconnection in high-traffic grow environments.
Not all M19 cords are the same. Voltage rating and length must be matched to the circuit. This SKU (10-010704-260) is the 277V, 10ft, straight variant. Flexstar offers other cord SKUs for 240V service and different lengths — confirm your facility's service voltage at the panel before ordering. If you're unsure, your electrical contractor can verify with a meter in under two minutes.
This cord is compatible with Flexstar LED fixtures that use the M19 power input connector and are rated for 277V operation — confirmed models include the Flexstar PRO 645W, 720W SE Series, and related commercial fixtures in the Flexstar lineup that list 120V/208V/240V/277V multi-voltage input. Always verify your specific fixture's voltage input range against your facility's service voltage before connecting.
At the circuit level, 277V service requires a correctly rated breaker, properly sized conductors from the panel, and a compatible outlet or whip termination. The power cord is the last link in that chain — it does not override upstream electrical requirements. Consult your licensed electrician for panel and distribution design.

This cord is designed for Flexstar LED fixtures that use an M19 power input connector and support 277V input — including the PRO 645W, 720W SE Series, and other multi-voltage Flexstar commercial fixtures. Always confirm your specific fixture's voltage input range in its documentation before connecting. Do not use a 277V cord on a fixture rated only to 240V.
No. Cord voltage rating must match your service voltage. This cord is rated for 277V service. Flexstar offers separate cord SKUs for 240V circuits — contact HSC and we'll specify the correct part for your facility's electrical configuration.
For most commercial ceiling-mount configurations where the circuit outlet or distribution whip is located in the overhead structure near the fixture, 10 feet is sufficient. If your outlet is positioned farther from the fixture than 10 feet, you'll need a longer run handled at the distribution level by a licensed electrician — extension cords are not a code-compliant substitute for proper circuit wiring.
No. This is a straight primary input cord, not a daisy-chain interconnect. It runs from your circuit outlet or whip to a single fixture's M19 input. Flexstar daisy-chain cords are separate SKUs with a different configuration. Contact HSC if you need daisy-chain interconnect cords for your installation.
Yes, each fixture requires its own input power cord. If you're specifying a multi-fixture room running 277V Flexstar units, plan one cord per fixture. HSC can quote project quantities — reach out with your fixture count and room layout.
