Matrix 277V 10ft straight M19 power cord

What This Cord Is

This is Matrix's OEM straight power cord engineered for 277V single-phase electrical systems — the voltage standard found in the vast majority of purpose-built commercial cultivation facilities across the United States. The cord runs 10 feet from the circuit receptacle to the fixture inlet, providing enough slack for a clean overhead installation without requiring additional extensions.

The supply-side plug is a NEMA L7-15P twist-lock — the industry-standard locking plug for 277V circuits. It engages with a quarter-turn into a matching L7-15R receptacle, creating a secure connection that resists accidental disconnection in active grow rooms. The fixture end uses an M19 push-lock connector, which is the input format specified for compatible Matrix fixtures. Straight-body (non-angled) cord format keeps the cable run tidy along fixture rails and reduces strain at the connector.

Power cords are sold separately from Matrix fixtures. This cord is the correct selection when your facility is wired at 277V and your fixture has an M19 inlet. If your circuit voltage is 120V or 240V, or if your fixture uses a different connector standard, select the appropriate cord for that voltage. Running the wrong voltage cord to a fixture will cause incorrect operation or equipment damage.

Compatible Fixtures and When You Need This Cord

This cord is compatible with Matrix fixtures that accept an M19 inlet and are rated for 277V operation — including the Matrix DE 1000W HPS fixture (208–277V model) and the Matrix Hybrid 1000W (208–277V model). Matrix linear toplight fixtures operating at 277V also use this cord format. Always verify the specific fixture's input voltage range and inlet connector type in its spec sheet before ordering.

277V is the preferred supply voltage in large commercial builds because running fixtures at higher voltage reduces current draw for the same wattage — which means smaller conductor gauge in home runs, less heat at connections, and more fixtures per circuit breaker. If your electrical contractor has specified 277V distribution panels for your cultivation space, this cord is what completes the connection between your panel receptacles and your Matrix fixtures.

Facilities running 208V or 240V distribution will need the corresponding Matrix cord for those voltages. Do not mix cord voltages across a single fixture row unless each circuit is individually confirmed. When in doubt, consult your electrical contractor to confirm the panel service voltage at each fixture row before specifying cords.

Connector and Plug Details

The NEMA L7-15P plug on the circuit side is a 2-pole, 3-wire grounding configuration — standardized for 277V, 15A North American circuits. The twist-lock mechanism seats and locks with a clockwise rotation, preventing the cord from being pulled free under load or during routine grow-room activity. The plug is designed for repeated insertion cycles and is the connector type specified by commercial electrical codes for 277V single-phase branch circuits.

The M19 push-lock on the fixture side provides a secure, tool-free connection to the fixture inlet. The M19 format is widely used across commercial horticultural lighting because it supports clean daisy-chain and point-to-point power delivery without exposed terminals. The straight-body exit angle on this cord keeps the cable running parallel to the fixture rail — preferred in tight overhead installations where an angled connector would create clearance conflicts with adjacent fixtures or mounting hardware.

Cord jacket construction is rated for the temperature and humidity conditions typical of enclosed indoor cultivation spaces. Run the cord through appropriate cable management (J-hooks, cable trays, or fixture-rail channels) to maintain a professional installation and reduce mechanical wear at the connectors over the fixture's service life.

Specifying Cords for a Commercial Lighting Build

On a multi-room or multi-tier build, power cord specification is a line item that's easy to miss until installation day. Every Matrix fixture requires one power cord, sold separately. For facilities with standardized 277V distribution, order this cord one-for-one with each fixture. If you have a mixed-voltage facility — for example, 208V in flower rooms and 277V in veg — track the cord type per room and label accordingly before your electrical rough-in.

Cord quantity and voltage should be confirmed during the lighting layout phase, not at move-in. Hydro Supply Co. can help you cross-reference fixture count, room voltage, and connector type during your pre-purchase consultation so you receive the correct cords alongside your fixtures in a single coordinated order.
