High-Performance LED Solution for Extreme Temperature Environments

For facilities that require dependable lighting in challenging thermal conditions, this 300-watt LED high temperature fixture delivers 39,000 lumens of bright illumination while operating reliably from -40°F to 194°F. Built with aluminum alloy construction and an oversized heat sink, this fixture ensures consistent performance in both extreme hot and cold environments where standard lighting solutions fail.

Key Advantages

  • Delivers exceptional 130 lumens per watt efficiency with 39,000 total lumens
  • Engineered to handle demanding conditions from -40°F to 194°F operating range
  • Provides reliable operation with dual voltage compatibility: 100V-277V or 347V-480V
  • Built with aluminum alloy housing and large heat sink for thermal management
  • Offers flexible beam angle options from focused 10° to wide 120° coverage
  • Ensures 70,000-hour lifespan with minimal maintenance requirements

Who This Fixture Is For

  • Industrial facilities with high ambient temperatures near furnaces or processing equipment
  • Cold storage operations requiring reliable lighting in freezer environments
  • Manufacturing plants where temperature fluctuations challenge standard fixtures
  • Processing facilities needing bright, consistent illumination in harsh conditions
  • Operators upgrading from 1000-watt metal halide systems for energy savings
  • Maintenance teams seeking long-lasting solutions in difficult-to-access locations

How It Compares to Metal Halide

Unlike traditional 1000-watt metal halide systems that struggle with temperature sensitivity and frequent lamp replacements, this LED fixture maintains consistent light output across its entire temperature range. With its specialized construction and thermal management design, it eliminates the warm-up time and color shifting common with metal halide while delivering comparable brightness at 70% less energy consumption.

Major Benefits

Energy Savings

Designed to deliver the same illumination as 1000-watt metal halide fixtures while consuming only 300 watts, this LED solution reduces energy costs by approximately 70%. Additionally, its high power factor above 0.95 and low harmonic distortion under 15% optimize electrical efficiency and reduce utility penalties.

Light Output & Visibility

Built with 5000K daylight color temperature and 80+ CRI, this fixture provides clear, accurate color rendering essential for detailed work and safety applications. In real-world use, the polycarbonate lens system distributes light evenly while protecting LED components from environmental contaminants.

Operating Stability

Engineered for high performance in extreme environments, the aluminum alloy housing and oversized heat sink ensure stable operation even when ambient temperatures reach 194°F. Performance-wise, this thermal management prevents LED degradation and maintains consistent light output throughout the fixture's 70,000-hour lifespan.

Installation Considerations

For most installations, this fixture accommodates both eye-hook and pendant mounting configurations, providing flexibility for various ceiling heights and structural requirements. From a safety perspective, the IP66 rating protects against dust ingress and water jets, while the 38.3-pound weight requires adequate structural support for the 19.6 x 16.53 x 8.65-inch housing dimensions.

Certifications & Ratings

  • ETL certified for safety and performance standards
  • IP66 rating for dust and water resistance
  • Operating temperature range certified from -40°F to 194°F
  • 50/60 Hz frequency compatibility for worldwide use

Warranty

  • 5-year comprehensive warranty coverage
  • Protection against manufacturing defects and premature failure
  • Support for installations in extreme temperature environments
