450 Watt LED High Mast Light | 69,750 Lumens | 5000K | 100V-277V or 277V-480V

Product Overview

This 450 watt LED high mast light delivers 69,750 lumens at 155 lumens per watt, operating at 5000K color temperature with a CRI of 70+. The fixture replaces 1000 watt metal halide systems and is available in two voltage configurations: 100V-277V or 277V-480V.

The housing is die-cast aluminum with a polyester paint finish rated for 5,000 hours of salt fog exposure. Prismatic glass optics deliver high application efficacy, uniformity, and glare control. The fixture ships with Type 5 distribution as standard, with optional beam patterns available including 60 degree, Type 2, Type 3, and Type 4.

This fixture mounts to a 2 3/8 in O.D. tenon with an adjustable angle mount. Four-bolt mounting and safety cables secure the fixture to the pole. Total fixture weight is 52 lbs with an EPA rating of 3.87. The fixture is gray.

Where This Product Fits Best

High mast applications where wide, uniform light distribution is required across large open areas benefit from this fixture''s specialized high mast optics. The Type 5 distribution pattern maximizes coverage for installations with multiple poles, though alternate distributions allow narrower or asymmetric patterns where site geometry requires it.

The IP66 rating allows installation in locations exposed to heavy rain, wind-driven dust, and direct water spray. The IK08 rating provides protection against physical impacts. Operating temperature range spans -4 degrees F to 122 degrees F, supporting year-round outdoor use in most climates.

The 5,000-hour salt fog rating on the polyester paint finish makes this fixture appropriate for coastal environments or industrial sites with corrosive atmospheres. The 3G vibration rating supports installation on poles subject to wind-induced movement or in areas with heavy vehicle traffic below.

Performance and Functional Considerations

At 69,750 lumens from 450 watts, this fixture achieves 155 lumens per watt. The 5000K color temperature provides neutral white light typical of outdoor area and security lighting applications. CRI of 70+ is standard for high mast installations where color rendering is secondary to coverage and visibility.

The fixture includes 10kV surge protection. Power factor exceeds 0.90 and total harmonic distortion is under 20%. Rated lifespan is 100,000 hours at L70.

Dimming is available via 0-10V protocol. Photocell control compatibility includes 3-pin, 5-pin, and 7-pin receptacle options.

Installation and Long-Term Use

The adjustable angle mount accommodates a 2 3/8 in O.D. tenon and allows aiming adjustment during installation. Four-bolt mounting secures the fixture to the tenon, and safety cables provide secondary retention. At 52 lbs, rigging and handling during installation or maintenance requires appropriate equipment and crew.

The EPA rating of 3.87 must be accounted for in pole and foundation calculations, particularly in high wind zones. Both voltage configurations support common service levels found in high mast installations across commercial and industrial sites.

The polycarbonate lens and die-cast aluminum housing require minimal maintenance under normal conditions. The 100,000-hour L70 lifespan reduces lamp change frequency compared to metal halide predecessors.

How This Fixture Is Commonly Used

Once installed, this fixture operates as a fixed-output area light with optional dimming and photocell control. The adjustable mount allows field aiming to account for pole placement, terrain, or overlap with adjacent fixtures. The 0-10V dimming input can be connected to building management systems or standalone controllers where output reduction is required during low-activity periods.

Operators selecting from the available beam angles choose based on pole height, spacing, and target coverage area. Type 5 provides symmetric wide distribution, while Type 2, Type 3, Type 4, and 60 degree options narrow or shape the pattern for specific site layouts.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. The IP66 rating allows exposure to powerful water jets and complete protection against dust ingress. The IK08 rating protects against moderate mechanical impacts.

Surge protection is rated at 10kV. The fixture operates in ambient temperatures from -4 degrees F to 122 degrees F.

We provide a 5-year warranty on this fixture.
