Brand: LIGHT EFFICIENT DESIGN

Looking to upgrade the lighting in your garage, workshop, or warehouse-style space? This LED retrofit lamp from Light Efficient Design is designed to replace traditional metal halide and HID fixtures without the hassle of a full fixture swap. Simply install it into your existing industrial fixture or high bay socket, and you'll immediately enjoy brighter, cleaner light that makes any large open area feel more inviting and functional. It's an ideal solution for homeowners tackling renovation projects in spaces with tall ceilings or open layouts.

Whether you're converting an old barn into a studio, finishing a basement with high ceilings, or breathing new life into a detached shop, this high bay retrofit bulb delivers reliable, even illumination right where you need it. Available in multiple wattage options and selectable color temperature configurations, it adapts to a wide range of residential and hobby spaces. Think of it as swapping out an old, energy-hungry industrial light for a modern, efficient alternative — with no rewiring and no new fixture required.

This lamp is certified to Canadian electrical standards and cUL approved, so you can install it with complete peace of mind knowing it meets the safety requirements for your home. It's open-rated for use in non-enclosed fixtures, making it a versatile choice for covered porches, carports, and other semi-exposed areas. If you've been putting off upgrading those old overhead lights, this retrofit makes the switch simple, safe, and surprisingly affordable.

This LED retrofit lamp leverages advanced solid-state lighting technology to deliver substantially more usable light per watt than the traditional HID and metal halide lamps it replaces. The result is a dramatic reduction in energy consumption — often cutting electricity use by more than half — while maintaining powerful, uniform output across large areas. A high CRI rating ensures that colors appear natural and true, which is especially important in workspaces where visual clarity matters for detail-oriented tasks.

At the heart of this lamp is an efficient LED driver engineered for consistent performance across a wide input voltage range, making it compatible with the vast majority of existing electrical systems found in Canadian homes and outbuildings. The driver is designed for long operational life and stable output, minimizing flicker and ensuring smooth, comfortable illumination from the moment you flip the switch.

Thermal management is a critical factor in LED longevity, and this retrofit lamp features a purpose-built heat dissipation system that channels warmth away from the LED array and driver components. This keeps internal temperatures within optimal ranges even during extended use, protecting the lamp's lifespan and maintaining lumen output over thousands of hours of operation. The open-rated design further supports passive airflow cooling, contributing to reliable performance in uncovered or ventilated fixture housings.

This product carries cUL and DLC certification, confirming compliance with rigorous Canadian electrical safety and energy efficiency standards. It is also eligible for many provincial utility rebate programs, which can help offset the upfront investment. Installation is straightforward — the mogul base fits directly into existing EX39 sockets, so there's no need for specialized tools or professional electricians in most cases. For homeowners looking to modernize older lighting systems while reducing ongoing energy costs, this retrofit lamp offers a practical, code-compliant, and future-ready upgrade path.
