150 Watt LED High Temperature Light | 19500 Lumens | 5000K | 100V-277V or 347V-480V | Rated to 194F

Product Overview

We offer a 150 Watt LED High Temperature Light designed for continuous operation in environments where ambient temperatures reach up to 194°F (90°C). This fixture is built for industrial spaces where standard LED high bays cannot withstand elevated heat, such as steel mills, foundries, and power generation facilities. The form factor is a compact UFO-style high bay, suitable for mounting heights typically found in heavy industrial and energy sector buildings.

This model is engineered to replace 400W metal halide fixtures in high temperature zones, providing reliable illumination in areas where heat exposure is a constant operational factor. The fixture is available in 100-277V or 347-480V configurations to accommodate a range of industrial electrical systems.

Core Performance and Output

This fixture delivers 19,500 lumens at 150 watts, with an efficacy of 130 lumens per watt. The 5000K color temperature provides a neutral white light suitable for task visibility in industrial process areas. Multiple beam angle options (10°, 25°, 40°, 90°, 120°) allow for targeted or wide-area coverage, supporting both focused and general illumination requirements.

Electrical performance includes a power factor above 0.95 and total harmonic distortion below 15%. The fixture is non-dimmable, which is typical for high temperature applications where simplicity and reliability are prioritized. Excessive output may occur at mounting heights below 15 feet; uniformity can decrease at heights above 35 feet depending on beam angle selection and spacing.

Adjustability and Control Options

This fixture is supplied without dimming or advanced control features. The design focus is on thermal resilience and operational stability in high heat environments. Beam angle selection is available at the time of order, allowing adaptation to specific area lighting needs.

Mounting options include eye-hook and pendant, supporting both chain and rigid conduit installations. There are no integrated sensors or wireless controls due to the high temperature rating and the need to minimize potential failure points.

Longevity and Reliability

The fixture is rated for 70,000 hours of continuous operation at elevated temperatures. The LED driver and board are thermally isolated and protected within an aluminum alloy housing to ensure consistent performance in environments up to 194°F (90°C).

Ingress protection is IP66, preventing dust and water intrusion during washdown or in humid process areas. The fixture is ETL listed and covered by a 5-year warranty for defects in materials and workmanship under normal use.

Build Quality and Physical Characteristics

The housing is constructed from corrosion-resistant aluminum alloy, finished in gray. The lens is polycarbonate, providing impact resistance and thermal stability. The fixture measures 14.17 x 13.77 x 8.65 inches and weighs 19 lbs, supporting robust mounting in vibration-prone or heavy-duty industrial settings.

All hardware and seals are specified for high temperature operation. The fixture is designed for vertical mounting and is not intended for wall or angled installations. The compact UFO form factor allows for installation in areas with limited overhead clearance.

Where This Product Fits Best

This fixture is intended for continuous use in industrial environments where ambient temperatures regularly exceed the limits of standard LED high bays. Typical installations include process areas, furnace zones, and energy sector facilities requiring reliable illumination under thermal stress.

• 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 with airborne dust, humidity, or periodic washdown are supported by the IP66 rating. The fixture is not suitable for hazardous (classified) locations or food processing areas requiring NSF certification.

Installation and Long-Term Use

Mounting is performed via eye-hook or pendant, supporting both chain and rigid conduit suspension. The fixture?s weight and dimensions require secure overhead structure and proper anchoring. Electrical connection is made through a sealed gland, with compatibility for both standard and high voltage industrial circuits.

Routine maintenance is minimal due to the sealed design and lack of moving parts. Periodic inspection of mounting hardware and lens cleanliness is recommended, especially in dusty or high-vibration environments. The fixture is designed for continuous operation and does not require scheduled lamp or driver replacement under normal conditions.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 35 feet, depending on the beam angle and required light levels. Narrow beam optics are used for tall process bays or to highlight specific equipment, while wide beam options support general area lighting. Spacing is determined by the selected optic and target uniformity, with higher output allowing for increased fixture spacing but potentially increasing glare if not shielded or aimed properly.

Installers often deploy these fixtures in grid or linear patterns above production lines, furnace aisles, or equipment clusters. The fixture is commonly used as a direct replacement for legacy HID high bays in high temperature zones, minimizing downtime during retrofit projects.

Safety, Certifications, and Warranty

This fixture is ETL listed and IP66 rated. All components are specified for operation in ambient temperatures up to 194°F (90°C). The polycarbonate lens and aluminum housing are impact and corrosion resistant. The product includes a 5-year warranty covering defects in materials and workmanship under normal use.

No hazardous location, NSF, or food grade certifications are included. The fixture is not intended for use in classified or explosion proof environments.
