The High Mast fixture (HM1) delivers powerful, reliable illumination for large outdoor environments, with high-output performance ranging from 29,000 to 108,000 lumens to maximize visibility, safety, and operational efficiency.
Built to withstand harsh weather and corrosive conditions, the HM1 features a rugged die-cast aluminum housing, advanced thermal management, and a 3G vibration rating for dependable performance in demanding applications. Precision optical distributions provide uniform coverage with reduced glare and light spill, directing light exactly where it is needed while minimizing maintenance and downtime.
For added flexibility and energy savings, the HM1 includes standard 0–10V dimming and a NEMA receptacle for easy field installation of photocell and wireless control sensors, enabling automated lighting control and future-ready smart functionality.
Applications: Automotive Lighting, Hangar Lighting, Industrial Lighting, Outdoor Lighting, Parking Garage Lighting, Sports Lighting.
Superior Heat Dissipation
Die-cast aluminum housing and heat sink improve thermal transfer, keeping LEDs cool to increase performance and life.
Wet Location Rated (IP65)
The fixture withstands extreme outdoor weather conditions and it is protected against dust, water, and contaminants.
NEMA Receptacle
Add a photocell sensor or an additional surge protector device at any time in the field. Twist Lock system, no tools or wiring needed.
