Light Efficient Design LED-8929E57-HAZ LED Hazardous Fixture Retrofit Lamp - E26 - 24W - 5700K - 3,400 Lumens - 120-277V

The Light Efficient Design LED-8929E57-HAZ Hazardous Location Retrofit Lamp is designed to upgrade existing hazardous-area lighting from HID to a safer, long-life LED solution. This post-top lamp uses a medium E26 base and operates on 120–277 V, enabling ballast bypass operation for compatible fixtures. It is specifically rated for Class I, Division 2 hazardous location environments (Groups A–D), making it suitable for installations where flammable or explosive atmospheres could be present. With a 5700 K color temperature, it emits bright, cool-white light and delivers up to 3,400 lumens from a 24-watt package, offering a practical replacement for up to a 150 W HID system. The lamp includes 10 kA surge protection and is engineered with active cooling and dynamic temperature control to help maintain performance and extend life expectancy, which is quoted at 50,000 hours.

In terms of compatibility and form, the LED-8929E57-HAZ is intended for use with hazardous location fixtures that accept a Crouse-Hinds Champ®, Appleton Mercmaster III and II, GE Filtr-Gard, Killark Certilite, and Thomas & Betts HazLux style lamp compatibility, aligning with common industrial fixture families. The physical dimensions—approximately 6.75 inches in length and 2.9 inches in diameter—along with its corn-cob lamp shape, support straightforward retrofits in existing post-top configurations. Keeping in mind the ballast bypass requirement and the environmental rating, this lamp is best suited for controlled, indoor or sheltered exterior locations where electrical codes permit Class I, Division 2 installations.

The product arrives as a single unit designed to replace HID lighting while maintaining appropriate brightness and color metrics for industrial spaces. It supports reliable operation across a wide temperature range from -40 to 113 degrees Fahrenheit, making it adaptable to varying facility conditions. When planning upgrades, verify fixture compatibility with the specific hazardous location standards and ensure proper electrical wiring practices for 120–277 V operation and ballast bypass to maximize performance and safety benefits.
