Product Overview
This 100 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, power plants, and energy facilities. The compact UFO form factor allows for installation in areas with limited overhead clearance or where robust, sealed construction is required.
Typical use cases include replacing 250W metal halide fixtures in high temperature zones, with mounting heights generally ranging from 15 to 30 feet. The fixture is suitable for both new construction and retrofit projects where thermal performance and reliability are critical.
Core Performance and Output
This fixture delivers 13,000 lumens at 100 watts, providing an efficacy of 130 lumens per watt. The output is consistent across the full rated temperature range, with no reduction in performance at elevated ambient temperatures. Multiple beam angle options (10°, 25°, 40°, 90°, 120°) allow for tailored light distribution based on ceiling height and task requirements.
Electrical performance includes universal voltage input (100-277V or 347-480V), power factor above 0.95, and total harmonic distortion below 15%. The fixture is non-dimmable. Excessive output may occur at mounting heights below 15 feet, and uniformity may be reduced if wide beam optics are used at maximum mounting heights.
Adjustability and Control Options
This model is supplied as a fixed-output fixture with no onboard dimming or integrated controls. Beam angle selection is available at the time of installation through interchangeable optics. The fixture supports both eye-hook and pendant mounting, allowing for flexibility in installation method based on site conditions.
No motion sensors, daylight harvesting, or networked control options are included. All adjustments must be made manually during installation.
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 LED driver and thermal management system are designed for high temperature endurance, minimizing risk of premature failure in demanding environments.
Ingress protection is rated at IP66, providing full protection against dust and high-pressure water jets. The fixture maintains performance and reliability in areas subject to airborne particulates, humidity, and washdown procedures.
Build Quality and Physical Characteristics
The housing is constructed from aluminum alloy for thermal conductivity and corrosion resistance. The lens is polycarbonate, offering impact resistance and optical clarity. The fixture measures 12 x 12 x 8.65 inches and weighs 13.2 lbs, supporting overhead mounting without excessive structural load.
All external hardware is designed for durability in industrial environments. The fixture is finished in gray and is suitable for installation in areas with exposure to dust, moisture, and high ambient heat.
Where This Product Fits Best
This fixture is intended for continuous use in high temperature industrial environments where standard LED or HID fixtures are not suitable. It is commonly installed in areas with sustained heat, airborne particulates, and the need for robust, sealed construction.
- high temperature facility lighting
- power plant and energy site lighting
- steel mill lighting
- foundry lighting
- industrial furnace area lighting
- nuclear facility lighting
- kiln lighting
- boiler room lighting
The fixture is suitable for both retrofit and new construction projects in heavy industrial settings. It is not intended for use in hazardous (classified) locations or areas requiring explosion proof certification.
Installation and Long-Term Use
Installation is typically performed using the supplied eye-hook or pendant mount. The fixture?s weight and compact size allow for single-person handling in most cases. Electrical connection supports both standard (100-277V) and high voltage (347-480V) systems, accommodating a range of industrial power infrastructures.
Routine maintenance is minimal due to the sealed design and long-life components. Periodic inspection of mounting hardware and lens cleanliness is recommended in environments with heavy dust or airborne debris. The fixture?s IP66 rating supports use in areas subject to washdown or high humidity.
How This Fixture Is Commonly Used
Common mounting heights range from 15 to 30 feet, depending on the required light levels and beam angle selection. Fixtures are typically spaced to achieve uniform coverage, with tighter spacing in areas requiring higher illumination or where narrow beam optics are used.
In high temperature zones, fixture count may be increased to offset any localized heat buildup or to maintain target light levels over time. Higher output per fixture can reduce the total number of fixtures required, but may increase glare if not paired with appropriate optics.
Safety, Certifications, and Warranty
This fixture is ETL listed and rated IP66. All components are specified for operation in ambient temperatures up to 194°F. The product includes a 5-year warranty covering manufacturing defects and component failure under normal operating conditions.
No hazardous location or explosion proof certifications are included. The fixture is suitable for use in industrial environments where high temperature and ingress protection are required.
