310 Watt LED Shoebox | 47430 Lumens | 5000K | 277-480V

Product Overview

This 310 watt LED fixture delivers 47,430 lumens at 153 lumens per watt. It is designed as a direct replacement for 1000 watt metal halide systems.

The fixture operates on 277V to 480V input and outputs a 5000K color temperature with a CRI of 70+. It is built with a die-cast aluminum housing and a polycarbonate lens.

Available mounting options include yoke, arm, or slip fitter. The fixture is finished in bronze and measures 22 inches long, 11.8 inches wide, and 3 inches high. Weight is 11.3 lbs.

Rated for 100,000 hours (L70), it includes 10kV surge protection and is designed for use in demanding environments.

Where This Product Fits Best

This fixture is suited for outdoor and large-area lighting applications where high output and durability are required. It is commonly used to replace legacy 1000 watt metal halide fixtures.

Type 3 optics provide a lateral distribution pattern suitable for roadway, parking lot, and perimeter lighting. The IP65 rating allows use in wet locations and exposure to dust and rain.

Operating temperature range is -40°F to 113°F, supporting installation in both cold and hot climates. The fixture's EPA rating of 1.7 should be considered when selecting poles for wind load compatibility.

Voltage compatibility from 277V to 480V supports use in commercial and industrial electrical systems.

Performance and Functional Considerations

The fixture delivers consistent output with a power factor greater than 0.90 and total harmonic distortion below 15%. It is non-dimming and operates at 50-60Hz.

Polycarbonate lens construction provides impact resistance and optical clarity. The die-cast aluminum housing supports long-term durability in outdoor environments.

Optional photocell functionality is available for dusk-to-dawn operation. Surge protection is rated at 10kV for electrical reliability.

Type 3 beam distribution is designed for wide lateral coverage, reducing the number of fixtures needed for uniform area lighting.

Installation and Long-Term Use

Mounting options include yoke, arm, or slip fitter, allowing adaptation to existing poles or wall structures. The fixture's weight and dimensions support single-person handling for most installations.

IP65 rating protects against water jets and dust ingress, supporting use in exposed outdoor locations. The fixture is suitable for both retrofit and new construction projects.

Operating temperature range allows year-round use in a variety of climates. The 100,000 hour L70 lifespan reduces maintenance intervals compared to legacy systems.

Bronze finish provides a neutral appearance for most commercial and industrial sites. The fixture is designed for minimal maintenance beyond periodic cleaning and inspection.

How This Fixture Is Commonly Used

Once installed, this fixture provides consistent, high-output illumination for parking lots, roadways, and exterior perimeters. The Type 3 distribution pattern delivers wide, even coverage across large areas.

Operators can select from yoke, arm, or slip fitter mounting to match site requirements. The fixture remains fixed in place after installation, with no dimming adjustments required.

Optional photocell integration allows for automatic dusk-to-dawn operation, reducing manual intervention. The fixture's robust housing and lens construction support reliable performance in harsh weather and high-traffic environments.

Routine maintenance is limited to visual inspection and cleaning, as the fixture is designed for long service life and minimal component replacement.
