Swap the lamp, keep the fixture, and watch your warehouse light up like a brand new building. The LED-8030M57-MHBC from Light Efficient Design is a high bay LED retrofit lamp — what people also call a corn lamp, a mogul base LED bulb or an HID replacement lamp — built to drop straight into your existing high bay or low bay housing. It threads into the standard EX39 mogul base you already have, so there is no new fixture to hang, no ceiling to re-drill and no new wiring to pull. With upward-facing LEDs that bounce light into the reflector of your enclosed high bay, it fills the room instead of punching one hot spot onto the floor, which is exactly what you want over aisles, racking and work stations. If you have been shopping high bay lighting or LED high bay lights and dreading the labour bill of a full fixture change-out, this is the shortcut.

This model delivers 140W of LED power and 17 047 lumens at 5700K, a crisp daylight white that sharpens contrast, helps crews read labels and gauges quickly and keeps a big space feeling alert rather than gloomy. Colour rendering is 80+ CRI, and the rated life is L70 50,000 hours, so re-lamping visits get rare. It replaces up to 400W HID on a 400W Probe or Pulse ballast — the existing ballast stays in place and simply drives the lamp, and that ballast input can be 120V, 208V, 240V, 377V, 347V or 480V. An integrated 6kA surge protector, advanced active cooling with dynamic temperature control, an insect and dust resistant housing, an operating range of -40°F to 122°F and approval for damp environments and enclosed fixtures round out the package.

It is a natural fit for warehouses, distribution centres, manufacturing floors, garages, repair shops, arenas, barns and municipal works buildings — anywhere Canadian winters push temperatures low and unheated bays still need reliable light. Because it is ballast compatible, a contractor can do dozens of fixtures in a single shift without touching the wiring. Need the same lamp in a warmer, more neutral white? Look at the LED-8030M40-MHBC high bay retrofit. For the outdoor side of the same property, the 110W shoe box and wall pack retrofit covers parking lots and building walls. Grab the spec sheet, confirm your ballast, and order your retrofit lamps today.

Built for retrofits, not for rewiring
The whole point of the LED-8030M57-MHBC is speed. It is a metal halide ballast compatible LED lamp, meaning it runs off the existing magnetic or electronic ballast already sitting in your high bay housing. Light Efficient Design rates the installation as easy to medium: no wiring, mogul base only. Your electrician removes the old HID lamp, threads in the LED, closes the fixture and moves to the next one. On a floor with fifty or a hundred bays, that difference in labour is the whole project budget. The lamp is compatible with both Pulse and Probe start ballasts, and the ballast input can be 120V, 208V, 240V, 377V, 347V or 480V, which covers the vast majority of Canadian industrial services.

Light quality and the upward LEDs
Old HID lamps are point sources: bright in the middle, dark at the edges, with shadows behind racking. This lamp uses upward-facing LEDs so part of the output is thrown into the reflector of the enclosed high bay and redistributed across a wider area. The result is a flatter, more even light field on the floor and fewer dark zones between fixtures. At 5700K, the output is a cool daylight white that reads as clean and bright, favoured for inspection tasks, picking and packing, and any area where safety depends on seeing edges and markings clearly. Colour rendering sits at 80+ CRI, enough to keep colour-coded bins, wiring and safety signage easy to distinguish.

Durability and thermal design
Heat is what kills retrofit lamps, so this family uses advanced active cooling with dynamic temperature control to keep the diodes in their comfort zone inside a closed reflector. The housing is insect and dust resistant, which matters in agricultural buildings, mills and any dusty production environment where bugs used to collect in the old fixture bowl. The integrated 6kA surge protection guards against the spikes that come with heavy equipment starting and stopping on the same service, and the -40°F to 122°F operating range means unheated storage buildings and cold-climate loading docks are fair game. Approval for damp locations and enclosed fixtures lets you keep the original glass lens or gasketed bowl in place.

Applications, family and documentation
Think distribution warehouses, machine shops, auto and truck service bays, recycling facilities, arenas, riding arenas, greenhouses and municipal garages. Anywhere a 400W metal halide is still humming away and taking minutes to restrike after a power blip, this lamp is the fast fix. Prefer 4000K for a softer, more neutral industrial white? The LED-8030M40-MHBC retrofit lamp is the same platform. For exterior HID on the same site, Light Efficient Design also offers the 80W shoe box and wall pack retrofit and the 50W shoe box and wall pack retrofit.
