300 Watt LED High Temperature Light | 45000 Lumens | 5000K | 100-277V | Rated to 212F

Product Overview

This 300 Watt LED High Temperature Light is engineered for continuous operation in environments where ambient temperatures reach up to 212°F (100°C). The fixture is designed for high bay mounting in industrial settings where heat, dust, and airborne contaminants are present. Typical installations include power plants, steel mills, foundries, and energy sector facilities where legacy 1000W metal halide fixtures are being replaced with more efficient, lower-maintenance solutions.

The fixture uses a UFO form factor with a robust aluminum alloy housing and polycarbonate lens. It is suitable for mounting heights from 25 to 50 feet, depending on the required light levels and layout. The IP66 rating and ETL certification support use in demanding, high-temperature industrial environments.

Core Performance and Output

This fixture delivers 45,000 lumens at 300 watts, providing 150 lumens per watt efficiency. The standard 90° beam angle offers broad, uniform coverage for open areas, with optional 25°, 40°, or 60° optics available for targeted or high-mount applications. The 5000K color temperature supports visual acuity in industrial process areas.

Electrical performance includes a power factor above 0.95 and THD below 15%. The fixture operates on 100-277V input at 50/60 Hz. At mounting heights below 25 feet, output may be excessive for some tasks and can increase glare. At heights above 50 feet, uniformity and target light levels may require closer fixture spacing or narrower optics.

Adjustability and Control Options

This fixture is non-dimmable and does not support integrated controls. Beam angle can be specified at order using interchangeable optics for different coverage requirements. Mounting options include eye-hook, pendant, or trunnion, allowing adaptation to existing structure or process equipment layouts.

No onboard occupancy or daylight sensors are included. External control systems must be specified separately if required for the application.

Longevity and Reliability

The fixture is rated for 100,000 hours (L70) at maximum ambient temperature. The aluminum alloy housing and polycarbonate lens are designed to withstand thermal cycling, vibration, and airborne particulates common in high-temperature industrial environments.

Integrated 6kV surge protection guards against electrical transients. The fixture maintains performance and lifespan when operated continuously at temperatures up to 212°F. No routine re-lamping is required, reducing maintenance in hazardous or hard-to-access locations.

Build Quality and Physical Characteristics

The fixture measures 22 x 19 x 4 inches and weighs 38 lbs. The housing is constructed from corrosion-resistant aluminum alloy with a gray finish. The polycarbonate lens is impact-resistant and sealed to IP66 for protection against dust and water ingress.

All mounting hardware is designed for secure installation in high-vibration and high-heat environments. The fixture is suitable for pendant, eye-hook, or trunnion mounting to accommodate a range of structural conditions.

Where This Product Fits Best

This fixture is intended for continuous use in high-temperature industrial environments where standard LED or HID fixtures fail due to heat exposure. It is commonly installed in:

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

Environments typically include process areas, production floors, and equipment bays with sustained high ambient temperatures, airborne particulates, and exposure to vibration or electrical noise.

Installation and Long-Term Use

Mounting options include eye-hook, pendant, or trunnion, supporting installation to structural steel, pipe, or custom brackets. The fixture?s weight and size require secure mounting points and may need two-person handling for overhead installation. All wiring must be rated for high-temperature service and comply with local codes.

Routine maintenance is limited to periodic inspection for dust buildup or lens cleaning. No lamp or driver replacement is required during the rated life. The fixture is designed for continuous operation in environments where shutdowns are infrequent or impractical.

How This Fixture Is Commonly Used

Typical mounting heights range from 25 to 50 feet, depending on the process area and required light levels. Spacing is determined by beam angle selection and target uniformity; narrower optics are used for higher mounting or focused task areas. Fixtures are often deployed in grid or linear patterns to match equipment layouts or process lines.

Higher output allows for reduced fixture count in large open bays, but may require glare mitigation or shielding in areas with direct line-of-sight to workstations. Layouts should account for heat sources and airflow patterns to avoid localized overheating.

Safety, Certifications, and Warranty

This fixture is ETL listed and rated to IP66 for dust and water ingress. It includes integrated 6kV surge protection and is designed for operation in ambient temperatures from -40°F to 212°F. The housing and lens materials are selected for durability in high-heat, high-vibration environments.

A 5-year warranty covers manufacturing defects and performance under rated conditions. All certifications and ratings are documented for compliance and inspection purposes.
