750 Watt LED High Mast Light | 112,500 Lumens | 5000K | 100-277V or 277-480V

Product Overview

This 750 Watt LED High Mast Light is engineered for large-scale outdoor area illumination where high mounting heights and broad coverage are required. Designed to replace 2000 Watt metal halide fixtures, it delivers 112,500 lumens at 5000K for demanding environments such as ports, airports, and highway interchanges. The fixture supports both 100-277V and 277-480V input, allowing integration into a range of site electrical systems.

Typical installations include pole-mounted arrays at heights from 60 to 120 feet, where uniformity and high output are critical. The housing is constructed from aluminum alloy with a polycarbonate lens, and the fixture is rated for continuous outdoor exposure.

Core Performance and Output

This high mast fixture outputs 112,500 lumens at 150 lumens per watt, providing efficient illumination for large exterior spaces. Standard distribution is Type 5, with optional 60°, Type 2, Type 3, and Type 4 optics to match site-specific requirements. The fixture maintains a power factor above 0.90 and total harmonic distortion below 20%.

At mounting heights above 80 feet, uniformity and coverage remain consistent with proper optic selection. Excessive output may result in glare or over-lighting at lower mounting heights or in smaller yards. For optimal results, match beam angle and output to the site layout and pole spacing.

Adjustability and Control Options

Standard dimming is 1-10V, supporting integration with external lighting controls or energy management systems. An optional photocell is available for dusk-to-dawn operation. Beam angle options allow for tailored light distribution based on site geometry and pole placement.

Adjustability is limited to the selected optic and control accessories at installation. No field-adjustable beam or color temperature features are included.

Longevity and Reliability

The fixture is rated for 100,000 hours (L70), supporting long-term operation in continuous-use environments. The aluminum alloy housing and polycarbonate lens provide resistance to impact and environmental exposure.

10kV surge protection is integrated to guard against transient voltage events common in outdoor electrical systems. The fixture operates reliably from -4°F to 122°F, suitable for most climates encountered in high mast applications.

Build Quality and Physical Characteristics

The fixture weighs 60 lbs and is designed for pole mounting. The housing is aluminum alloy with an IK08 impact rating and IP66 ingress protection, supporting installation in exposed outdoor locations. The polycarbonate lens resists yellowing and impact damage.

All hardware and mounting interfaces are engineered for structural stability at height. The fixture is UL listed for safety and code compliance.

Where This Product Fits Best

This high mast light is suited for large-scale exterior environments requiring high-output, uniform illumination from elevated mounting points. It is commonly deployed in transportation, industrial, and infrastructure settings where reliability and coverage are critical.

• port lighting
• airport lighting
• highway interchange lighting
• large yard lighting
• sports complex lighting
• industrial yard lighting
• rail yard lighting
• freight terminal lighting

Environmental characteristics include exposure to wind, precipitation, and airborne contaminants. The IP66 and IK08 ratings support use in harsh outdoor conditions, including coastal and industrial sites.

Installation and Long-Term Use

Pole mounting is standard, with all necessary hardware designed for secure attachment at heights up to 120 feet. The fixture?s weight and wind profile should be considered when specifying pole and foundation requirements. Electrical connections accommodate both 100-277V and 277-480V systems.

Routine maintenance is minimized by the sealed housing and long LED lifespan. Periodic inspection of mounting hardware and surge protection is recommended, especially in high-wind or corrosive environments.

How This Fixture Is Commonly Used

Typical mounting heights range from 60 to 120 feet, with fixture spacing and aiming determined by site layout and required light levels. Arrays of 4 to 8 fixtures per pole are common in ports and interchanges, while single or double fixtures may be used in smaller yards or terminals.

Beam angle selection and pole spacing directly affect uniformity and glare. Higher output can reduce fixture count but may require careful aiming to avoid light trespass or excessive brightness in adjacent areas.

Safety, Certifications, and Warranty

This fixture is UL listed and meets IP66 and IK08 ratings for ingress and impact protection. Integrated 10kV surge protection is included. The product is covered by a manufacturer?s warranty; refer to documentation for terms and coverage details.

All components are rated for outdoor use and comply with relevant safety standards for high mast lighting installations.
