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 5000K. It is designed for high-output applications requiring broad, uniform coverage from elevated mounting heights.

The fixture uses a die-cast aluminum housing with a polyester paint finish and a 5,000-hour salt fog rating. Prismatic glass optics and specialized high mast distributions are built in for wide-area illumination and glare control.

Voltage options include 100V-277V or 277V-480V. The fixture supports 0-10V dimming and offers multiple beam angle options, including Type 5 (standard), 60°, Type 2, Type 3, and Type 4.

Mounting is via an adjustable angle mount for 2 3/8" O.D. tenons, secured with a 4-bolt system and safety cables. The fixture is gray and weighs 52 lbs.

Where This Product Fits Best

This fixture is suited for high mast lighting applications where broad, uniform light distribution is required. Typical environments include large outdoor areas, sports venues, transportation yards, and industrial sites with multiple pole installations.

It is intended as a direct replacement for 1000 Watt metal halide systems, providing high lumen output and improved efficacy. The fixture is compatible with both standard and high-voltage electrical systems.

Environmental ratings and corrosion resistance make it suitable for locations exposed to weather, salt, and vibration. The 3G vibration rating supports use in areas subject to wind or mechanical movement.

Performance and Functional Considerations

The fixture delivers 155 lumens per watt and a total output of 69,750 lumens. The 5000K color temperature provides a neutral white light suitable for visibility and security in large outdoor spaces.

Beam angle options allow for tailored light distribution based on site requirements. Type 5 is standard, with optional 60°, Type 2, Type 3, and Type 4 distributions available for different coverage patterns.

The fixture operates with a power factor greater than 0.90 and total harmonic distortion below 20%. Surge protection is rated at 10kV. The fixture is rated for operation from -4°F to 122°F.

IP66 and IK08 ratings provide protection against dust, water, and moderate impact. The fixture is UL listed.

Installation and Long-Term Use

The fixture mounts to a 2 3/8" O.D. tenon using an adjustable angle bracket. Four-bolt mounting and safety cables are included to secure the fixture to the pole.

The die-cast aluminum housing and polyester finish are designed for durability in outdoor environments, including areas with salt exposure. The 5,000-hour salt fog rating supports use in coastal or industrial locations.

The fixture is 3G vibration rated, supporting installation in areas subject to wind or mechanical vibration. The EPA rating is 3.87.

Expected lifespan is 100,000 hours (L70). Maintenance requirements are minimized due to the sealed housing and robust construction.

How This Fixture Is Commonly Used

Once installed, this fixture provides consistent, high-output illumination for large outdoor areas. The wide distribution optics are designed to maximize coverage and uniformity across multiple poles.

Beam angle selection allows you to match the light pattern to the site layout. Type 5 is used for circular or square coverage, while other options can be specified for rectangular or perimeter lighting.

The fixture supports 0-10V dimming, allowing integration with lighting controls for energy management or scheduling. Photocell control is available for automated dusk-to-dawn operation.

Routine operation does not require user intervention. The sealed housing and impact resistance reduce the need for frequent inspection or service.
