Light Efficient Design LED-8924M50-HAZ LED Hazardous Fixture Retrofit Lamp - EX39 - 45W - 5000K - 6,620 Lumens - 120-277V

The Light Efficient Design LED-8924M50-HAZ is a hazardous location retrofit lamp designed to upgrade existing EX39 mogul-base fixtures from HID to LED illumination. With a 45-watt LED engine, it delivers about 6,620 lumens at a 5000K color temperature, providing a bright, white light suitable for demanding industrial environments. The lamp is built for hazardous locations, specifically Class 1 Division 2, Groups A–D, and is compatible with post-top, EX39 mogul bases used in many hazardous area luminaires. Its form factor and surge-protected electronics support reliable operation in challenging sites while offering a long service life, backed by a 50,000-hour rated life. The design includes active cooling and dynamic temperature control, helping maintain performance and longevity in elevated ambient temperatures common in industrial spaces.

Construction and features focus on compatibility and robustness: the lamp bypasses traditional ballasts on 120–277V systems (Type B ballast bypass), simplifying installation and reducing potential points of failure. It is UL-certified for compatibility with several widely used hazardous-location fixtures and brands, ensuring a smoother retrofit process where retrofit lamps need to match the profile and electrical requirements of existing luminaires. The EX39 Mogul base and corn-cob LED shape provide a familiar retrofit form factor while delivering high efficacy and compact dimensions suitable for vertical post-top fixtures. The lamp replaces up to 250W HID output, enabling meaningful energy savings and heat reduction in facilities that operate HID lighting in hazardous areas. Technical performance, including a wide operating temperature range from -40°F to 113°F, supports use in temperature-extreme environments typical of manufacturing, chemical processing, and other high-risk settings.

Practical considerations include sizing, mounting, and maintenance implications: a 7.8-inch length and 3.4-inch diameter fit standard EX39 mogul sockets and post-top configurations, with a robust 10kA surge protection rating to withstand electrical transients. When planning retrofits, verify fixture compatibility with the listed hazardous location approvals and ensure the ballast bypass approach aligns with your electrical system. This lamp is intended as a direct retrofit for compatible hazardous-location luminaires, offering energy savings, consistent color temperature, and extended service life compared with legacy HID sources.
