The LED-8242M50D-HV is a high bay retrofit lamp designed to upgrade existing high bay fixtures to energy-efficient LED illumination. With a 270-watt draw, it replaces a 1,000-watt HID equivalent while delivering 35,425 lumens and a 5000K cool white color temperature. This Mogul EX39 base lamp is suitable for enclosed fixtures and damp locations, helping facilities improve light output and reduce energy use in demanding industrial environments.
Constructed to operate in 277–480V systems, the lamp features a 0–10V dimming interface that allows continuous dimming down to 20% to align lighting levels with processes or occupancy schedules. An integrated active cooling system supports reliable performance, contributing to a rated life of up to 50,000 hours. The design includes ballast bypass operation and 6 kA surge protection, which can simplify installation and enhance resilience in harsh sites. The physical form measures about 10.3 inches in diameter and 12.5 inches in height, making replacement straightforward in many standard high bay luminaires.
Designed for retrofit projects, this lamp is intended to deliver significant energy savings and improved light quality in warehouses, manufacturing floors, and other industrial applications where high-bay lighting is essential. It’s compatible with 277–480V electrical infrastructure and supports 0–10V control to fit into existing dimming schemes. When selecting this lamp, confirm fixture compatibility with an EX39 Mogul base and the enclosure rating to ensure proper operation in your specific environment. Regular maintenance should consider cooling fan function and occasional checks on voltage and dimming control performance to preserve the rated lumen output and life expectancy.
