The Light Efficient Design 135W Open Rated High Bay Retrofit (SKU: LED-8132M40CD) is a purpose-built LED lamp designed to breathe new life into aging HID high bay installations. By replacing fixtures that consume up to 400 watts of HID power, this retrofit can cut energy usage by over 65%, significantly lowering hydro bills and reducing your facility's carbon footprint — all without the need for a full fixture replacement.
The EX39 mogul screw base is the industry standard for high-wattage commercial and industrial lamps, ensuring direct compatibility with the vast majority of existing high bay reflector housings. Combined with a universal 120-277V operating voltage, this retrofit is suitable for virtually any North American electrical system — making it equally at home in a Canadian warehouse running 347V-adjacent infrastructure or a standard 120V facility.
At 4000K (neutral white), the LED-8132M40CD produces a balanced, daylight-adjacent color temperature that enhances visibility and reduces eye fatigue for workers on long shifts. Unlike HID sources that require warm-up time, this LED retrofit delivers instant full brightness from the moment it's switched on — a critical advantage for facilities with motion-sensor controls or frequent on/off cycling.
The open-rated construction means this lamp is approved for use in open fixtures — those without a glass or lens enclosure — which is the most common configuration for industrial high bay reflectors. This rating is an important compliance and safety consideration when specifying replacement lamps for commercial and industrial applications across Canadian provinces.
As a Light Efficient Design product, the LED-8132M40CD is backed by a brand known for engineering-led innovation in the commercial LED sector. Lumibox is proud to offer this premium retrofit lamp to Canadian electrical contractors, facility managers, and lighting specifiers looking for a proven, high-performance HID replacement that delivers measurable ROI.
