Light Efficient Design LED-8929M57-HAZ LED Hazardous Fixture Retrofit Lamp - EX39 - 24W - 5700K - 3,400 Lumens - 120-277V

Light Efficient Design LED-8929M57-HAZ is a hazardous location retrofit lamp designed to upgrade existing EX39/Mogul-type fixtures to LED illumination. This 24-watt luminaire delivers approximately 3,400 lumens at 5,700 K with a corn-cob style geometry and an EX39 Mogul base, enabling direct replacement for up to 150 W HID sources. The lamp operates on a 120–277 V supply and supports Type-B ballast bypass operation, which eliminates ballast components in compatible fixtures and can reduce maintenance points in hazardous areas. A key safety feature is the lamp’s suitability for Class I Division 2 environments (Groups A, B, C, D), aligning with standard hazardous location classifications while providing high color rendering (CR I 80+ as specified) for clearer visibility of potential hazards.

Constructed to withstand demanding conditions, the design includes active cooling and dynamic temperature control, helping manage heat under operation and extending service life. The unit is rated for a long service life of up to 50,000 hours, and it includes 10 kA surge protection to help guard against power transients that can occur in industrial settings. With its EX39 Mogul base and appropriate size metrics (approximately 6.75 inches in length and 2.9 inches in diameter), the lamp is intended for retrofit into compatible hazardous-location fixtures such as common industrial housings from brands like Crouse-Hinds Champ’, Appleton Mercmaster III/II, GE Filtr-Gard, Killark Certilite, and Thomas and Betts Hazlux, among others.

This product is specified to replace up to 150 W HID lighting and provides a 5700 K color temperature for a cooler, daylight-like appearance. When considering installation, users should verify fixture compatibility with ballast bypass configurations, fixture type, and approval for Class I, Division 2 service. Packaging details are per each unit, and the lamp is designed for continuous operation within its stated temperature range of -40°F to 113°F, ensuring reliable performance in typical hazardous-location applications.
