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

Product Overview

This 310 Watt LED Shoebox fixture delivers 47,430 lumens at a 5000K color temperature. It is designed for use on 277V to 480V electrical systems and serves as a direct replacement for 1000 Watt metal halide fixtures.

The fixture uses a Type 3 beam angle and a polycarbonate lens for area distribution. It is constructed with a die-cast aluminum housing and finished in bronze.

It operates at 50-60Hz, with a power factor greater than 0.90 and total harmonic distortion below 15%. The fixture measures 22 inches long, 11.8 inches wide, and 3 inches high, with a weight of 11.3 pounds.

The expected lifespan is 100,000 L70 hours. Surge protection is rated at 10kV. An optional photocell is available.

Where This Product Fits Best

This fixture is suited for outdoor area lighting applications where high output and wide coverage are required. Typical uses include parking lots, roadways, and perimeter lighting for commercial and industrial properties.

The 277-480V compatibility supports installation in facilities with higher voltage distribution. The Type 3 distribution pattern is appropriate for roadway and large area coverage.

Its EPA rating of 1.7 allows for mounting on poles where wind load is a consideration. The fixture is designed for environments where exposure to dust and water is expected.

Operating temperature range from -40°F to 113°F supports use in both cold and hot climates.

Performance and Functional Considerations

The fixture provides 153 lumens per watt, supporting high efficiency requirements. The 5000K color temperature delivers a daylight-white output suitable for visibility and security applications.

With a CRI of 70+, the fixture provides adequate color rendering for general area lighting. The polycarbonate lens is impact resistant and suitable for outdoor use.

Surge protection at 10kV supports operation in areas with electrical disturbances. The fixture is non-dimming and does not support variable output control.

The power factor above 0.90 and THD below 15% meet typical requirements for commercial electrical systems.

Installation and Long-Term Use

Mounting options include yoke, arm, or slip fitter, allowing for attachment to a range of pole and bracket types. The fixture?s weight and dimensions support single-person handling for most installations.

The die-cast aluminum housing provides durability and corrosion resistance for long-term outdoor use. The IP65 rating allows the fixture to operate in locations exposed to rain, dust, and water jets.

Operating temperature range supports installation in both cold and hot environments. The fixture is designed for minimal maintenance over its rated lifespan.

Optional photocell integration is available for dusk-to-dawn operation. The fixture color is bronze, matching standard site lighting hardware.

How This Fixture Is Commonly Used

Once installed, the fixture provides consistent area illumination with a Type 3 distribution pattern. The output level is fixed, with no dimming or variable control required during operation.

The fixture can be mounted using yoke, arm, or slip fitter hardware, depending on the pole or structure. After mounting, no routine adjustments are needed.

If a photocell is used, the fixture will automatically switch on and off based on ambient light. Otherwise, operation is controlled by the site?s electrical circuit.

Maintenance is limited to periodic inspection and cleaning of the lens and housing as needed. The fixture is designed for long-term reliability in outdoor environments.
