The Light Efficient Design LED-8132M40D 135W LED high bay retrofit is purpose-built for facilities that rely on high-intensity discharge lighting and want a straightforward, cost-effective path to LED. With an EX39 mogul screw base, installation is as simple as removing the old HID lamp and screwing in the new unit — no ballast wiring changes required in most compatible fixtures. This dramatically reduces labour costs and downtime during the lighting upgrade process.
One of the standout features of this retrofit is its open-rated design, meaning it can operate safely and efficiently in open or partially open fixture housings — a common configuration in industrial high bay environments. Unlike enclosed-only LED lamps, the LED-8132M40D maintains stable thermal performance even without a fully sealed housing, ensuring consistent output and extended lifespan in real-world conditions.
The 4000K colour temperature delivers a neutral white light that is ideal for task-intensive applications such as assembly lines, warehouse picking aisles, sports facilities, and large retail floors. This colour temperature closely mimics natural daylight, reducing eye strain for workers during long shifts and improving the accuracy of colour-critical tasks. Combined with high lumen output replacing up to 400W HID, the energy savings are substantial and immediate.
Broad voltage compatibility from 120V to 277V makes this lamp a versatile choice for Canadian commercial and industrial facilities regardless of their electrical infrastructure. Whether your building operates on standard 120V circuits or higher-voltage industrial systems, the LED-8132M40D integrates without the need for additional transformers or adapters. This flexibility is especially valuable in retrofit scenarios where electrical panels serve mixed-voltage environments.
As a Light Efficient Design product, the LED-8132M40D is backed by a reputation for engineering quality and field-tested reliability. For distributors and facility managers across Canada, this means confidence in product performance, longevity, and the significant reduction in maintenance calls that comes with switching from HID to LED technology. It represents a true long-term investment in lighting infrastructure.
