LED Corn Bulb

What Is an LED Corn Bulb?

An LED corn bulb is a retrofit lamp that replaces older HID, metal halide, and HPS bulbs in fixtures you already own. The rows of LED chips wrapped around the body look like kernels on a cob, which is where the name comes from. You unscrew the old bulb, screw in the corn bulb, and the fixture runs cooler and cheaper. Most installs take minutes.

For commercial sites, the appeal is simple. You cut wattage by roughly three quarters, drop the heat, and stop replacing burned-out HID lamps every couple of years.

LED Corn Bulbs for Contractors and Facilities

Votatec sells corn bulbs the way wholesale buyers need them: by the case, with spec sheets, DLC listings, and Canadian stock. We work with electrical contractors, facility managers, building owners, and government procurement teams who are retrofitting warehouses, parking structures, street lighting, and shop bays.

• Bulk and contract pricing. Quote-based pricing scaled to project volume, not single-unit retail.
• DLC listed for rebates. DLC listing is the gate for Save on Energy and most provincial utility incentives. Off-the-shelf retail bulbs that lack it earn a zero-dollar rebate.
• Spec sheets and photometrics on request. Everything your designer or inspector needs.
• Canadian supply. Stocked in the GTA and shipped nationwide, so lead times stay short.

Where Do You Use LED Corn Light Bulbs?

Corn bulbs fit anywhere an HID or metal halide lamp used to run. The high-output models suit big open spaces; the lower wattages handle wall packs and post-tops.

• Outdoor LED Corn Bulbs for Street Lights and Parking Lots

Weatherproof corn bulbs drop into shoebox fixtures, cobra heads, and parking lot poles. Look for an IP64 rating and a wide operating temperature range for Canadian winters.

• LED Corn Lamps for Warehouse and Shop Fixtures

High-bay and low-bay fixtures take E39 mogul corn lamps in the 100W to 150W range. The result is bright, even daylight across racking and work areas with far less heat than metal halide.

Which LED Corn Bulb Base Do You Need?

Corn bulbs come in two main screw bases. Match the base to your existing socket.

• E26 LED Corn Light Bulbs

The E26 medium base is the standard screw size used in most residential and light-commercial fixtures. E26 corn bulbs cover the lower wattage range and suit wall packs, post-tops, and smaller enclosures.

• E39 LED Corn Lamps (Mogul Base)

The E39 mogul base is the larger socket found in high-bays, street lights, and high-output HID fixtures. E39 corn lamps carry the higher wattages and lumen packages. If your old bulb was 250W metal halide or bigger, you likely need E39.

LED Corn Bulb Wattage and Lumen Output

Pick wattage by the fixture you're replacing, not by habit. A modern corn bulb produces the same light at roughly a quarter of the wattage.

• 30W-50W LED Corn Light Bulb (Small Applications)

Replaces 100W-175W metal halide. Good for wall packs, canopy lights, and smaller post-tops.

• 60W-80W Corn Bulbs LED (Medium Applications)

Replaces 200W-320W metal halide. Suits mid-size area lights and low-bay fixtures.

• 100W-120W LED Corn Lamp (Large Applications)

Replaces 320W-400W metal halide. The workhorse for high-bays, parking lots, and street lighting.

• 150W+ Corn Lamps (Maximum Output)

Replaces 400W-1000W HID. For tall warehouses, sports areas, and high-pole applications where you need maximum lumens from a single lamp.

Weatherproof and Temperature Ratings

• IP64 Weatherproof LED Corn Light

An IP64 rating means the lamp is dust-protected and shielded from splashing water, which is what enclosed and semi-enclosed outdoor fixtures need. Confirm the host fixture is rated for enclosed use before installing.

• Wide Temperature Range LED Corn Lamp

Canadian sites swing from -40 to summer heat. A wide operating temperature range keeps output and lifespan steady through both, which matters for unheated warehouses and exterior poles.

LED Corn Bulb vs Metal Halide: The Numbers

The case for switching is mostly arithmetic. Here's what changes when a corn bulb replaces a metal halide lamp.

Across a building full of fixtures, the wattage cut and the longer service life are what move the payback math. DLC listing then layers utility rebates on top.
