High-Temperature Industrial LED Solution

For facilities that require dependable lighting in extreme heat conditions, this 300-watt LED fixture delivers 39,000 lumens while operating reliably at temperatures up to 176°F. Built for environments where traditional lighting fails, this fixture combines specialized thermal management with robust die-cast aluminum construction to ensure consistent performance in demanding industrial applications.

Engineered to handle demanding conditions with 3G vibration testing and an oversized heat sink design, this fixture provides a direct replacement for 1000-watt metal halide systems while consuming 70% less energy. What makes this fixture valuable for buyers is its ability to maintain L70 performance for 100,000 hours even in the harshest thermal environments.

LED vs Legacy Technology

  • Replaces 1000-watt metal halide fixtures while consuming only 300 watts
  • Eliminates warm-up time and frequent lamp replacements common with traditional systems
  • Maintains consistent 5000K color temperature without degradation over time
  • Operates reliably in extreme temperatures where metal halide systems typically fail
  • Reduces maintenance costs with 100,000-hour lifespan versus 20,000 hours for metal halide

Why This Fixture Performs

  • Delivers exceptional energy efficiency at 130 lumens per watt with .95 power factor for reduced operating costs
  • Provides bright, consistent illumination with 39,000 lumens and 70+ CRI for improved visibility
  • Reduces downtime thanks to specialized thermal design and 5-year warranty coverage
  • Strengthens safety through IP66 weatherproofing and IK10 impact resistance in harsh environments

Installation Guide

This fixture accommodates flexible installation requirements with both eye-hook and trunnion mounting options for various ceiling heights and angles. In practice, the compact 26.9 x 14.4 x 9.6 inch profile simplifies retrofits in existing metal halide locations, while dual voltage options (100V-277V or 277V-480V) ensure compatibility with most electrical systems without additional transformers.
