HM04 High Mast Roadway and Area Lighting, For Large-scale Outdoor Illumination

Product Overview

The HM04 Series LED High Mast Light is an industrial-grade, high-output luminaire engineered for large-area outdoor illumination where broad, uniform light distribution is non-negotiable. Delivering up to 200 lm/W efficacy with a scalable wattage range from 300W to 800W, this fixture is the performance-driven alternative to legacy metal halide and high-pressure sodium high mast systems.

Built around Lumileds 5050 LED chips and driven by UL-listed Inventronics drivers, the HM04 Series combines long-term photometric reliability with robust mechanical durability. The ADC12 aluminum die-cast housing provides superior thermal management, ensuring stable lumen output across the full operating life of the fixture.

Whether illuminating a port terminal at 100 feet or a stadium access plaza at 60 feet, the HM04 delivers the footcandle levels and distribution consistency demanded by commercial, infrastructure, and industrial procurement specifications.
