400 Watt LED High Temperature Light | 52000 Lumens | 5000K | 100V-277V or 347V-480V | Rated to 194F

Product Overview

The 400 Watt LED High Temperature Light is engineered for continuous operation in environments where ambient temperatures reach up to 194°F (90°C). This fixture is designed for high bay mounting in industrial settings where conventional lighting fails due to heat exposure. Typical installations include power generation plants, steel mills, and nuclear facilities where reliability under thermal stress is critical.

This model replaces 1000W metal halide fixtures, providing a robust LED solution for high temperature zones. The fixture supports both 100-277V and 347-480V input, allowing integration into a range of industrial electrical systems.

Core Performance and Output

This fixture delivers 52,000 lumens at 400 watts, achieving an efficacy of 130 lumens per watt. Multiple beam angle options?10°, 25°, 40°, 90°, and 120°?support both focused and wide-area illumination. The polycarbonate lens maintains optical clarity under prolonged heat exposure.

Output is suitable for mounting heights from 30 to 60 feet, with higher wattage supporting wider fixture spacing. At lower mounting heights, output may be excessive and increase glare. Uniformity can decrease at extreme mounting heights if beam angle selection is not matched to the application.

Adjustability and Control Options

This fixture is available with fixed-output operation and does not include dimming capability. Beam angle selection is set at the time of order and cannot be adjusted in the field. The fixture supports both eye-hook and pendant mounting for installation flexibility.

No onboard controls or sensors are included. External control integration is not supported due to the fixture?s high temperature design constraints.

Longevity and Reliability

The fixture is rated for 70,000 hours of continuous operation at full output in ambient temperatures up to 194°F. The aluminum alloy housing and polycarbonate lens are selected for thermal stability and resistance to deformation or discoloration under heat.

All electrical components are specified for high temperature operation. The IP66 rating ensures protection against dust and water ingress, supporting reliable performance in harsh industrial environments.

Build Quality and Physical Characteristics

The housing is constructed from corrosion-resistant aluminum alloy with a gray finish. The fixture measures 22 x 20.86 x 8.65 inches and weighs 45.8 lbs. The polycarbonate lens is impact-resistant and maintains optical performance at elevated temperatures.

All hardware is designed for mechanical stability under vibration and thermal cycling. The fixture is ETL listed and suitable for use in wet locations.

Where This Product Fits Best

This fixture is intended for continuous use in industrial environments with sustained high ambient temperatures. It is commonly installed in facilities where standard LED or HID fixtures fail due to heat exposure or require frequent maintenance.

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

The fixture?s IP66 rating and high temperature tolerance make it suitable for dusty, humid, or wet industrial environments. It is not intended for use in hazardous (classified) locations or where explosion proof certification is required.

Installation and Long-Term Use

Mounting options include eye-hook and pendant configurations. The fixture?s weight and size require secure attachment to structural supports rated for at least 50 lbs. Electrical connections must be made using high temperature-rated wiring and junction boxes.

Routine cleaning of the lens and housing is recommended to maintain optical performance in dusty or particulate-laden environments. No field-serviceable parts are included; replacement is required at end of life.

How This Fixture Is Commonly Used

Typical mounting heights range from 30 to 60 feet, depending on the required light levels and beam angle selection. Fixtures are spaced to achieve uniform coverage, with closer spacing for narrow beam optics or higher task illumination.

In high bay industrial settings, higher output allows for reduced fixture count, but may increase glare if not paired with appropriate optics or shielding. Layouts are often grid-based or follow process lines in manufacturing and energy facilities.

Safety, Certifications, and Warranty

This fixture is ETL listed and rated IP66 for wet locations. All components are specified for continuous operation at ambient temperatures up to 194°F. The product includes a 5-year warranty covering manufacturing defects and performance under rated conditions.

No hazardous location or explosion proof certifications are included. Installation must comply with local electrical and safety codes for high temperature environments.
