Light Efficient Design LED-8242M40-HV LED High Bay Retrofit Lamp - EX39 - 270W - 4000K - 34,415 Lumens - 277-480V

Light Efficient Design’s LED-8242M40-HV is a high bay retrofit lamp designed to replace 1,000 W HID fixtures with a 270 W LED solution. Built for demanding industrial environments, this Mogul EX39 base lamp provides bright, long-lasting illumination while offering compatibility with recessed or enclosed high bay fixtures and damp locations. The unit is engineered for extended life, featuring a rated 50,000 hours of operation and an operating temperature range suitable for a variety of facilities. Its 34,415 lumens and 4000 K color temperature deliver a cooler, daylight-like light output that helps improve visibility in large spaces such as warehouses and manufacturing floors. The inclusion of active cooling supports reliable performance by managing heat in operation, which is especially important for enclosed fixtures where heat buildup can be a concern. The lamp also incorporates ballast bypass capability (Type B) and is rated for use with 277–480 V electrical systems, aligning with common industrial power distributions. With an enclosure-friendly design and 6 kA surge protection, it offers resilience against electrical transients often encountered in facility environments. The physical dimensions indicate a compact form factor suitable for high bay form factors, and its dimensions are specified as roughly 10.3 inches in diameter and 12.5 inches in height, aiding in fixture compatibility assessment. This lamp serves as a direct retrofit option for upgrading energy use in existing high bay installations, enabling substantial energy savings while maintaining compatibility with standard high bay mounting configurations.
