300 Watt LED High Temperature Light | 39000 Lumens | 5000K | 100V-277V or 347V-480V | Rated to 194F

Product Overview

This 300 Watt LED High Temperature Light is engineered for continuous operation in environments where ambient temperatures reach up to 194°F (90°C). The fixture is designed for high bay mounting in industrial settings that experience sustained heat, such as steel mills, foundries, and power generation facilities. Its robust construction and thermal management allow it to replace 1000W metal halide fixtures in areas where standard LED high bays cannot maintain performance or longevity.

Typical installations include mounting heights from 25 to 45 feet in high temperature zones, including furnace areas, boiler rooms, and energy production sites. The fixture?s sealed housing and IP66 rating support deployment in dusty or humid conditions common to these environments.

Core Performance and Output

This fixture delivers 39,000 lumens at 300 watts, providing an efficacy of 130 lumens per watt. The output is suitable for large, high-ceilinged industrial spaces requiring high light levels and uniform coverage. Multiple beam angle options (10°, 25°, 40°, 90°, 120°) allow for tailored distribution, from focused task lighting to wide-area illumination.

Electrical performance is stable across 100V-277V or 347V-480V input, with a power factor above 0.95 and THD below 15%. Excessive output may occur at mounting heights below 20 feet, and uniformity can be reduced at extreme heights if wide beam optics are selected without proper spacing.

Adjustability and Control Options

The fixture is available with a range of optical distributions to match application requirements. Beam angle selection enables adaptation to both targeted and general lighting needs within high temperature zones. There is no onboard dimming or integrated control system; output is fixed at full power.

Mounting options include eye-hook and pendant configurations, supporting both new installations and one-for-one retrofits. The fixture is not designed for dynamic aiming or field-adjustable output.

Longevity and Reliability

Rated for 70,000 hours of operation, this fixture is built for long-term use in continuous-duty, high temperature environments. The thermal management system and aluminum alloy housing maintain LED and driver performance at elevated ambient temperatures.

Ingress protection is IP66, preventing dust and water intrusion. The fixture is ETL certified and covered by a 5-year warranty. Lifespan may be reduced if operated above rated temperature or in environments with poor airflow around the fixture.

Build Quality and Physical Characteristics

The housing is constructed from corrosion-resistant aluminum alloy, with a polycarbonate lens for impact resistance and thermal stability. The fixture measures 19.6 x 16.53 x 8.65 inches and weighs 38.3 lbs, supporting secure mounting in overhead applications.

All external hardware is designed for durability in harsh industrial settings. The fixture color is gray, and all electrical components are sealed against dust and moisture. The design supports both pendant and eye-hook mounting methods.

Where This Product Fits Best

This fixture is intended for continuous operation in high temperature industrial environments where standard LED high bays are not suitable. It is commonly installed in areas with sustained ambient heat, airborne particulates, and the need for high lumen output at elevated mounting heights.

• high temperature facility lighting
• steel mill lighting
• power plant and energy site lighting
• nuclear facility lighting
• industrial furnace area lighting
• foundry lighting
• kiln lighting
• boiler room lighting

Environments include heavy industrial plants, energy production sites, and process areas with high ambient temperatures, airborne dust, and humidity. The fixture?s IP66 rating and thermal design support reliable operation in these demanding conditions.

Installation and Long-Term Use

Installation is typically performed using the supplied eye-hook or pendant mount, with secure attachment to structural steel or concrete. The fixture?s weight and size require proper support and safe handling during installation at height. Electrical connections accommodate both standard and high voltage inputs.

Routine maintenance is minimal due to the sealed housing and long LED life. Periodic inspection of mounting hardware and cleaning of the lens may be required in dusty or particulate-heavy environments. The fixture is not field-serviceable beyond basic cleaning and inspection.

How This Fixture Is Commonly Used

Common mounting heights range from 25 to 45 feet, depending on the application and required light levels. Spacing is determined by beam angle selection and target illuminance, with tighter spacing for narrow optics or higher task lighting requirements.

Fixtures are often deployed in grid or linear patterns to provide uniform coverage in large open bays or process areas. Higher output reduces the total fixture count but may increase glare if not paired with appropriate optics or mounting height.

Safety, Certifications, and Warranty

This fixture is ETL certified and rated IP66 for dust and water ingress. It is designed for safe operation in high temperature industrial environments, with all electrical and mechanical components rated for continuous exposure to elevated ambient temperatures.

The product includes a 5-year warranty covering manufacturing defects and performance within rated conditions. All safety and certification markings are present on the fixture housing for inspection and compliance verification.
