Product Overview
This 450 watt LED high mast light produces 69,750 lumens at 5000K for pole-mounted exterior lighting. It is configured for high-output coverage across large outdoor areas.
The fixture replaces a 1000 watt metal halide system and is available in 100V-277V or 277V-480V input voltage configurations. Its Type 5 distribution supports broad-area lighting from elevated pole locations.
Core Performance and Output
The fixture delivers 69,750 lumens at 155 lumens per watt. The 5000K color temperature and 70+ CRI provide a cool white output for large-site visibility.
Type 5 optics are standard. Optional 60 degree, Type 2, Type 3, and Type 4 distributions allow the optical pattern to match the pole location and site layout.
Power factor is greater than 0.90, and total harmonic distortion is less than 20 percent. This output level can be excessive where poles are installed at lower mounting heights or where the lighting area is limited.
Adjustability and Control Options
This high mast light supports 0-10V dimming. Dimming allows output adjustment where the electrical control system is designed for 0-10V operation.
Optical distribution is selected through the available beam angle options. Type 5 is the standard distribution, while the other available optics address more directional or controlled layouts.
Longevity and Reliability
The rated lifespan is 100,000 L70 hours. L70 identifies the point at which light output is rated to remain at 70 percent of initial output.
A 10kV surge protection device helps protect the fixture from electrical surge events. The operating temperature range is -4 degrees F to 122 degrees F.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a gray finish. The fixture weighs 52 pounds and uses a polycarbonate lens.
IP66 and IK08 ratings support outdoor exposure and impact resistance. Pole mounting requires the pole, mounting assembly, and support structure to accommodate the fixture weight and 3.87 EPA rating.
Where This Product Fits Best
This fixture fits high-output exterior installations where poles serve large outdoor coverage areas. Its output, Type 5 distribution, pole mounting, and IP66 rating align with elevated site lighting.
- port lighting
- airport lighting
- highway interchange lighting
- large yard lighting
- industrial yard lighting
- rail yard lighting
- freight terminal lighting
Its die-cast aluminum construction, IP66 rating, IK08 rating, and operating temperature range support exposed outdoor installations. Final optical selection depends on the required distribution pattern across the site.
Installation and Long-Term Use
This fixture mounts to a pole. Installation requires confirmation of the selected voltage configuration, pole mounting arrangement, fixture weight, and 3.87 EPA rating.
Mounting height is determined by the pole and lighting layout rather than a fixed fixture mounting range. The electrical installation must support the selected voltage and any 0-10V dimming controls.
How This Fixture Is Commonly Used
For port lighting, airport lighting, highway interchange lighting, and large yard lighting, fixtures are positioned on poles to direct output across broad exterior areas. Type 5 optics are used where a wide distribution is needed from the pole location.
Industrial yard lighting, rail yard lighting, and freight terminal lighting layouts typically use pole locations and optical distribution to manage coverage across the planned area. Higher output can reduce the number of fixture locations, but the final layout must account for mounting height, target light levels, and the selected optic.
Safety, Certifications, and Warranty
This fixture is UL listed. It is rated IP66 and IK08.
The fixture includes 10kV surge protection. No warranty terms are provided in the supplied product data.
