Flexstar 120V 10ft straight M19 power cord

What This Cord Is

This is the OEM Flexstar power cord for fixtures that use the M19 circular connector and are running on 120V service. The M19 is a high-current circular connector used across Flexstar's LED grow light lineup to connect the fixture or power supply enclosure to line voltage. The straight plug orientation — as opposed to an angled or right-angle configuration — is the standard fitment for most panel and outlet runs where the cord exits the outlet parallel to the wall.

At 10 feet, the cord gives operators enough slack to hang fixtures at commercial mounting heights without pulling tight against the outlet or requiring an additional extension. This is the correct cord to order when your facility runs standard North American 120V circuits and your Flexstar fixture is spec'd for that voltage. If your service is 208V, 240V, or 277V, a different voltage-matched cord is required — do not mix service voltages.

Voltage Matching: Why It Matters

Flexstar's commercial LED fixtures are multi-voltage capable, supporting 120V, 208V, 240V, and 277V inputs. The fixture's driver handles the conversion internally, but the power cord must match the service voltage at the outlet. Running a 120V cord on a 240V circuit — or vice versa — risks cord and driver damage and voids warranty coverage. This cord is specifically rated for 120V service.

On a 120V circuit, a 645W Flexstar fixture draws approximately 5.4A. Verify that your circuit and outlet are appropriately rated for the total load across all fixtures on that breaker. For facilities running higher-density fixture counts, consider whether stepping up to 240V or 277V service (with the corresponding cord and outlet) would reduce per-circuit amperage load — but that's a separate cord and a separate conversation with your electrician.

Connector Detail: The M19

The M19 is a circular power connector used in Flexstar's LED fixture ecosystem to create a secure, positive-lock connection between the fixture's power supply enclosure and the incoming AC line. Per Flexstar's own installation documentation, the M19 female connector on the power cable mates with the M19 male connector on the power supply enclosure. The connector is designed for easy plug-and-unplug servicing without tools, while providing a mechanically secure fit that resists accidental disconnection in a busy grow environment.

Always confirm the connector type on your specific Flexstar fixture before ordering. Flexstar produces multiple fixture lines and accessory cord configurations — the M19 straight cord at 120V is the correct SKU (10-010704-019) for 120V M19-equipped installations. If you are unsure which cord your fixture requires, reach out to HSC before placing the order.

Who Orders This and When

This cord is a maintenance and build-out accessory, not a one-time purchase for most commercial operations. Licensed cannabis and hemp facilities order spares to keep production running if a cord is damaged, cut, or fails during a cycle — fixture downtime in a flowering room has a real cost per day. Facilities expanding their fixture count also order additional cords alongside new fixtures to ensure each new fixture has its own properly-rated cable.

Operators retrofitting grow rooms from HID to LED, or rewiring a room to tighten up cable management, often find existing cords are the wrong length, the wrong voltage rating for the new fixture, or simply worn from years of use. Having Flexstar OEM cords on hand rather than sourcing aftermarket replacements keeps your warranty intact and removes the guesswork on connector fitment. HSC can coordinate cords as part of a larger fixture order or as a standalone accessory order — request a quote to discuss quantities.
