Brand: LIGHT EFFICIENT DESIGN

Looking to upgrade the lighting in your garage, workshop, or large open space? This high bay retrofit lamp from Light Efficient Design is a simple, cost-effective way to breathe new life into your existing industrial fixture or warehouse light without replacing the entire unit. It screws right into your current mogul base socket, making it one of the easiest upgrades you can tackle during a renovation — no electrician needed for the bulb swap itself. Think of it as giving your old ceiling light a modern LED brain.

Whether you're converting a barn, updating a shop, or finishing a large rec space with high ceilings, this LED retrofit bulb delivers powerful, even illumination across wide areas. It's available in multiple wattage options and a selectable color temperature range to suit the look and feel you want — from a crisp, productive atmosphere to a warmer, more inviting glow. It's designed to replace traditional HID and metal halide lamps, so you get dramatically better light quality with a fraction of the energy use.

Built for the Canadian market, this lamp is certified to Canadian electrical standards and cUL/CSA approved, giving you peace of mind that it meets rigorous safety requirements. It's also rated for use inside enclosed fixtures, so you won't have to worry about compatibility with your existing high bay housing, canopy light, or industrial ceiling fixture. Light Efficient Design has a strong reputation for reliability, making this a smart long-term investment for any large-space lighting project.

This Light Efficient Design LED retrofit lamp uses advanced LED technology to produce consistent, high-quality light output over an exceptionally long rated lifespan. With a high CRI rating, colors in your space will appear more natural and true-to-life compared to the yellowish cast of older HID or metal halide lamps. The internal optics are engineered to distribute light evenly across large areas, reducing dark spots and improving overall visibility in high-ceiling applications.

At the heart of this lamp is an efficient LED driver built to operate on higher voltage electrical systems commonly found in commercial and industrial-style installations. The driver is designed for reliable performance and features built-in surge protection to guard against power fluctuations. This level of driver quality translates directly into stable, flicker-free operation and a longer overall product life, meaning fewer replacements and less maintenance over time.

Thermal management is a critical factor in any enclosed-rated LED product, and this lamp is engineered with an advanced heat dissipation system that keeps internal temperatures in check — even inside sealed fixtures. This enclosed rating sets it apart from many retrofit options on the market and ensures safe, sustained performance without thermal throttling or premature failure. The lamp holds relevant certifications including cUL/CSA approval and is DLC listed, which may qualify you for utility rebate programs available across many Canadian provinces.

From an energy savings perspective, upgrading from a traditional HID lamp to this LED retrofit can reduce your lighting electricity consumption significantly — often by more than half — while actually improving light levels. Installation is straightforward: simply remove your old HID bulb and any existing ballast, complete the simple direct-wire connection to line voltage, and screw in the new lamp. The result is a modern, energy-efficient lighting solution that lowers your utility bills and reduces maintenance headaches for years to come.
