PHOTOBIO X Cable Harness, 18AWG, 277V Locking, L7-15P, 10 ft

PHOTOBIO X Power Harness — 18AWG, 277V, NEMA L7-15P Locking Plug, 10 ft

For PHOTOBIO X LED fixtures installed on 277V commercial circuits, this 18AWG harness with NEMA L7-15P locking plug delivers reliable power with a secure, vibration-resistant connection. The locking plug twists into the receptacle to prevent accidental disconnection — essential in a busy grow facility where cables get bumped and moved regularly.

277V is common in large-scale commercial and industrial electrical installations. At 277V, fixture current draw is lower than at 120V or 240V for the same wattage, reducing wire sizing requirements and enabling more fixtures per circuit. Combined with the plug-and-play IP connector at the fixture end, this harness gives commercial growers both efficient power delivery and convenient fixture-level disconnection.

Key Features & Benefits

• NEMA L7-15P locking plug — twisting locking mechanism prevents accidental disconnection — ideal for commercial grow environments with heavy cable traffic.
• 18AWG wire — appropriate for 277V PHOTOBIO X fixture current at rated operating wattage.
• IP connector at fixture — dust- and liquid-resistant IP connector for plug-and-play power management at the fixture.
• 10 ft white UV-resistant cable — 10 ft reach; white jacket reflects light back into the canopy.
• PHOTOBIO X compatible — for use with PHOTOBIO CX, MX, T, and TX LED fixtures on 277V circuits.

Who Should Use This Harness

Commercial growers with 277V dedicated circuits installing PHOTOBIO X LED fixtures who need a secure locking plug connection at the wall and plug-and-play IP connection at the fixture.

Why Locking Plugs Matter in Commercial Grow Rooms

In a busy commercial grow room, cables get pushed, pulled, and bumped as plants are moved, trellised, and harvested. A standard non-locking plug can work loose from a receptacle during normal operations, cutting power to a fixture unexpectedly. Locking plugs like the NEMA L7-15P twist into the receptacle and require a deliberate counter-twist to remove — preventing accidental disconnection and the crop loss that can follow an unnoticed power outage to a light fixture.

Frequently Asked Questions

What is an L7-15P plug?

The NEMA L7-15P is a 277V AC locking plug rated for 15 amps. The 'L' indicates a locking design — the plug twists into the receptacle to secure it against accidental removal. It is commonly used in commercial and industrial 277V installations.

What fixtures is this harness compatible with?

Compatible with PHOTOBIO CX, MX, T, and TX LED fixtures.

Why is 277V used in commercial lighting?

277V is common in commercial buildings because it is derived directly from a 480V three-phase system (480V ÷ √3 ≈ 277V). Running lighting at 277V reduces current draw for a given wattage, allowing more fixtures per circuit and reducing wiring costs.

What is the difference between this and the 5-15P or 6-15P versions?

The L7-15P is a 277V locking plug for commercial circuits. The 5-15P (CHE1063010W) is a 110-120V standard plug; the 6-15P (CHE1063015W) is a 208-240V standard plug. Choose the harness that matches your circuit voltage and receptacle type.

Is a licensed electrician required to install this harness?

The bare wire and plug wiring should always be handled by a licensed electrician. Once installed, the IP connector at the fixture end allows trained grow room staff to connect and disconnect the fixture without electrical expertise.
