Drop-In LED Retrofit That Eliminates Your 1000W HID for Good The Light Efficient Design 270W Enclosed Rated High Bay Retrofit (LED-8242M40D-HV) is engineered for industrial and commercial facilities that demand serious energy savings without a full fixture replacement. Designed to directly replace up to 1000W HID lamps using the standard EX39 mogul base, this retrofit slips into your existing high bay housing and immediately transforms your lighting performance — no rewiring, no new fixtures, no downtime. Built for Demanding High-Voltage Environments This unit operates on high voltage input ranging from 277V to 480V, making it the ideal solution for Canadian industrial facilities, warehouses, manufacturing plants, arenas, and distribution centres where high-voltage electrical systems are standard. The enclosed-rated design means it can be safely installed in enclosed fixture housings without thermal risk — a critical feature often overlooked with standard retrofits. Crisp 4000K Neutral White Light for Maximum Productivity At 4000K (neutral white), this retrofit delivers bright, balanced illumination that enhances visibility, reduces eye strain, and improves worker safety on the floor.
