Product Overview

This 600 Watt LED high mast light delivers 90,000 lumens at 5000K. It is designed for pole mounting in large outdoor or high-ceilinged spaces that require wide, uniform illumination. The fixture is built with a die-cast aluminum housing and a polyester paint finish rated for 5,000 hours of salt fog exposure.

Prismatic glass optics and specialized high mast distributions provide broad, even coverage with controlled glare. The fixture supports both 100-277V and 277-480V input ranges. It is equipped with 0-10V dimming and a power factor above 0.90.

The standard beam angle is Type 5, with optional 60°, Type 2, Type 3, or Type 4 optics available. The fixture is 3G vibration rated and includes a 10kV surge protector. It weighs 57 lbs and is designed for long-term outdoor use.

Mounting is achieved via an adjustable angle mount for a 2 3/8 in O.D. tenon, secured with a 4-bolt system and safety cables. Photocell control is available with 3/5/7-pin options.

Where This Product Fits Best

This fixture is suited for high mast lighting applications where wide-area coverage and high output are required. Typical environments include large parking lots, sports complexes, transportation terminals, and industrial yards.

It is intended as a direct replacement for 1500 Watt metal halide systems, offering comparable or improved illumination with lower power consumption. The fixture is compatible with both standard and high-voltage electrical systems.

The IP66 rating allows use in outdoor and wet locations, including areas exposed to rain, dust, and wind-driven debris. The 5,000-hour salt fog rating supports installation in coastal or corrosive environments.

The 3G vibration rating makes this fixture suitable for mounting on poles subject to wind or mechanical vibration, such as those found along highways or in open lots.

Performance and Functional Considerations

The fixture delivers 150 lumens per watt, providing high efficacy for large-scale lighting needs. The 100,000-hour L70 lifespan supports long-term operation with minimal maintenance.

Beam angle options allow adaptation to site-specific requirements, from wide area coverage (Type 5) to more focused distributions (Type 2, 3, 4, or 60°). The prismatic glass optics and polycarbonate lens manage glare and improve uniformity.

With a power factor above 0.90 and total harmonic distortion below 20%, the fixture operates efficiently on both 100-277V and 277-480V circuits. The 10kV surge protection guards against voltage spikes common in outdoor installations.

The fixture operates in ambient temperatures from -4°F to 122°F. The EPA rating of 3.87 should be considered when evaluating wind loading on poles.

Installation and Long-Term Use

The fixture mounts to a 2 3/8 in O.D. tenon using an adjustable angle bracket. The 4-bolt mounting system and safety cables provide secure attachment to the pole, minimizing risk of movement or detachment under vibration or wind load.

The die-cast aluminum housing and polyester finish resist corrosion and physical impact. The IP66 enclosure protects internal components from water and dust ingress, while the IK08 rating allows the fixture to withstand moderate impacts.

Photocell control is available for automated dusk-to-dawn operation. The fixture supports 0-10V dimming for integration with compatible lighting control systems.

Routine maintenance is minimized by the 100,000-hour rated lifespan and robust construction. The fixture?s weight of 57 lbs should be considered during installation planning and when selecting mounting hardware.

How This Fixture Is Commonly Used

After installation, this fixture provides consistent, high-output illumination for large outdoor areas. The wide distribution optics are used to maximize coverage between poles, reducing dark spots and improving visibility.

Operators can select from multiple beam angles to match site layout and lighting requirements. The adjustable mounting bracket allows precise aiming to direct light where needed.

The fixture?s 0-10V dimming capability supports integration with lighting control systems for scheduled or adaptive operation. Photocell options allow for automatic on/off based on ambient light levels.

Once installed, the fixture requires minimal attention aside from periodic inspection, due to its long rated life and durable construction. The IP66 and IK08 ratings allow for reliable operation in harsh weather and high-traffic environments.
