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

Product Overview

This 750 watt LED high mast fixture produces 112,500 lumens at 150 lumens per watt and operates at 5000K color temperature with a CRI of 70+. It replaces 2000 watt metal halide systems. The fixture is available in two voltage configurations: 100-277V or 277-480V, both rated for 50-60Hz operation.

The housing is die-cast aluminum alloy with a polyester paint finish rated for 5,000 hours of salt fog exposure. Prismatic glass optics deliver wide light distribution with glare control, and the standard beam angle is Type 5. Optional beam angles include 60 degrees, Type 2, Type 3, and Type 4. The polycarbonate lens protects the optical assembly.

This fixture mounts to a 2 3/8 in O.D. tenon with an adjustable angle mount. A 4-bolt mounting system combined with safety cables secures the fixture to the pole. The unit weighs 60 lbs. Dimming is available via 1-10V standard, with optional dimming configurations. Photocell control is available in 3, 5, or 7-pin configurations.

Where This Product Fits Best

This high mast fixture is built for elevated pole-mounted applications where wide area coverage is required from significant mounting heights. The Type 5 standard distribution and optional beam patterns support installations involving multiple poles covering large open areas. The specialized high mast optics are designed to maximize light spread across these configurations.

The IP66 rating allows the fixture to operate in locations exposed to heavy rain, wind-driven water, and airborne dust. The IK08 impact rating provides resistance to physical contact that can occur at height. The 5,000-hour salt fog rating on the housing finish makes this fixture suitable for coastal installations or facilities where corrosive airborne particles are present.

Operating temperature range spans -40 degrees F to 122 degrees F, supporting year-round outdoor use in extreme climates. The 3G vibration rating addresses installations on poles subject to wind-induced movement or locations near heavy equipment or traffic.

Performance and Functional Considerations

At 112,500 lumens from 750 watts, this fixture delivers output equivalent to a 2000 watt metal halide system while drawing significantly less power. The 150 lumens per watt efficacy reflects current LED high mast performance levels. Power factor exceeds 0.90 and total harmonic distortion is below 20%.

The 5000K color temperature produces a bright white light appropriate for security, safety, and visibility across large outdoor spaces. The 70+ CRI supports general visual recognition tasks typical of parking areas, storage yards, and perimeter lighting.

Rated lifespan is 100,000 hours at L70, meaning the fixture maintains at least 70% of initial lumen output through that operating period. The 10kV surge protection addresses electrical transients common in outdoor and utility-fed installations.

Installation and Long-Term Use

The fixture attaches to a 2 3/8 in O.D. tenon using an adjustable angle mount. The 4-bolt mounting system and safety cables provide redundant securing, which is standard practice for high mast installations where fixtures must remain locked to the pole under wind load and vibration. At 60 lbs, rigging and lifting equipment will typically be required during installation.

The dual voltage availability allows the fixture to be specified for either 100-277V or 277-480V electrical systems. This covers most commercial and industrial service configurations. Photocell receptacles in 3, 5, or 7-pin configurations support dusk-to-dawn automation when paired with compatible photocells.

The aluminum alloy housing and polyester finish are designed to resist corrosion over extended outdoor exposure. The IP66 and IK08 ratings define the environmental and physical protection limits for long-term deployment.

How This Fixture Is Commonly Used

Once installed, the adjustable angle mount allows the fixture to be aimed during initial setup to direct light where it is needed across the coverage area. The beam angle selection made at time of order determines the light spread pattern, so aiming adjustments work within that distribution type.

Facilities using photocell control operate the fixture automatically based on ambient light levels. The 1-10V dimming capability allows integration with external controls where reduced output is needed during specific hours or conditions. Optional dimming configurations extend compatibility with other control systems.

The 100,000-hour rated lifespan and durable construction reduce the frequency of maintenance access at height. The safety cable system provides a secondary attachment point during any service work performed on the fixture.

Safety, Certifications, and Warranty

This fixture is UL listed. It is rebate eligible through applicable utility programs.

The IP66 rating means the fixture is protected against dust ingress and high-pressure water jets from any direction. The IK08 rating means the fixture can withstand moderate mechanical impact. Surge protection is rated at 10kV.

We provide a 5-year warranty on this fixture.
