Matrix LTL 10ft 277V Power Cord

What This Cord Is

The Matrix LTL 10ft 277V Power Cord is the purpose-built input cord for Matrix Linear Toplight (LTL) fixtures operating on 277V single-phase service — the standard voltage distributed by most commercial lighting panels in large-scale indoor grow rooms and greenhouse facilities. It features an M19 fixture-side connector that mates directly with the LTL fixture's input port, and a 277V-rated plug on the service side.

Matrix sells fixtures and power cords separately, which means you need to specify the correct cord at the time of ordering. This 277V variant (SKU 10-010704-305) is for facilities wired to 277V. If your electrical infrastructure runs 240V instead, Matrix offers a separate 240V cord for the LTL line — confirm your panel voltage with your electrician before ordering.

Who Needs This Cord

Any licensed cannabis or hemp cultivation facility running Matrix LTL fixtures on a 277V electrical system needs this cord. 277V is the single-phase leg of a 480V three-phase wye distribution system, which is standard in purpose-built commercial cultivation facilities, warehouse conversions, and large controlled-environment agriculture (CEA) greenhouses. If your facility was designed or retrofitted for commercial horticultural lighting loads, there's a reasonable chance your lighting circuits are wired at 277V.

This cord is also the right call when you're adding Matrix LTL fixtures to an expansion zone, a new room, or additional canopy square footage in a facility already running 277V service. Running the wrong voltage cord — or an improperly rated aftermarket cord — creates both a safety hazard and a compliance issue. Spec the correct OEM cord from the start.

Key Features

The cord features an M19 connector on the fixture end — the same connector type used across Matrix's commercial linear toplight platform — ensuring a secure, keyed connection that won't back out. The 10-foot length is designed to reach from a commercial lighting circuit junction, track, or power distribution strip to the fixture's input point cleanly, without requiring additional extension cords that introduce resistance and potential code concerns.

The cord is built with heavy-duty insulation rated for the voltage and thermal demands of a continuously-operating commercial grow room environment. The straight-body configuration keeps the run tight to the fixture and reduces mechanical stress at the connector — relevant in facilities where rows of fixtures are hung close together and cord routing matters for safety and airflow.

How It Fits a Commercial Build

In a commercial Matrix LTL installation, each fixture requires its own input cord matched to the facility's service voltage. A 40-light room running 277V needs 40 of this cord. Ordering cords as part of the initial fixture purchase — rather than sourcing them separately after delivery — keeps your commissioning timeline on track. Facilities that have missed this step have dealt with delayed turn-on dates waiting for cords to arrive.

If you're spec'ing a new room or an expansion and are unsure whether your electrical layout is 277V or 240V, confirm with your licensed electrician before placing the cord order. The voltage on your panel schedule will be definitive.
