LED Corn Bulbs - HID Replacement Corn Lights

At LeanLight, we stock professional-grade LED corn bulbs from trusted brands including Keystone Technologies, Euri Lighting, and Sylvania / LEDVANCE. Choose from fixed or selectable wattage and color temperature models with E26 medium or EX39 / E39 mogul bases — ready for parking lots, warehouses, high-bay fixtures, outdoor post tops, and more.

Why Switch to LED Corn Bulbs?

• Massive energy savings – Replace 100W–400W HID lamps with 18W–120W LED corn bulbs while maintaining or increasing light output
• Long lifespan – 50,000-hour rated life reduces maintenance costs in hard-to-reach fixtures
• Instant-on & no warm-up – Full brightness immediately, unlike traditional HID
• Omni-directional light – 360° coverage ideal for open fixtures and high-bay applications
• Selectable options – Many models offer 3-in-1 or 9-in-1 wattage + CCT selection (3000K / 4000K / 5000K) via a simple switch or knob
• Ballast bypass design – Most units operate directly on 120–277V for maximum efficiency and reliability
• Enclosed fixture rated – Many models are IP64 or higher and approved for use in enclosed outdoor fixtures

Common Applications for LED Corn Lights

• Warehouse & industrial high-bay lighting
• Parking lot and parking garage fixtures
• Street and roadway post-top lights
• Sports courts and outdoor area lighting
• Canopy and gas station lighting
• Security and flood lighting
• Commercial and institutional building exteriors

How to Choose the Right LED Corn Bulb

1. Base Type
• E26 (medium base) – common in smaller fixtures and some post tops
• EX39 / E39 (mogul base) – standard for most HID high-bay, parking, and roadway fixtures

2. Wattage & Lumen Output
Match the LED wattage to the existing HID wattage using a roughly 3:1 or 4:1 ratio (e.g., a 54W–63W LED corn bulb typically replaces a 175W–250W metal halide). Selectable-wattage models give you flexibility on-site.

3. Color Temperature
• 3000K – warm white (residential or architectural feel)
• 4000K – neutral / bright white (most commercial applications)
• 5000K – cool daylight (warehouses, security, outdoor areas)

4. Voltage & Driver Type
Almost all of our LED corn bulbs are 120–277V universal voltage and designed for ballast-bypass installation (remove or bypass the existing ballast).

5. Environment
Look for “enclosed fixture rated” or IP64+ models when installing in outdoor or damp locations.

Frequently Asked Questions

What is an LED corn bulb?
An LED corn bulb (or corn cob LED) is a high-output LED lamp shaped like a corn cob. Hundreds of LED chips arranged around a cylindrical heat sink produce 360° light, making them ideal direct replacements for traditional HID (metal halide and high-pressure sodium) bulbs.

Do LED corn bulbs need a ballast?
Most modern LED corn bulbs are ballast-bypass (Type B). You remove or disconnect the existing HID ballast and wire the socket directly to line voltage (120–277V). Always follow the manufacturer’s installation instructions and local electrical codes.

Can I use LED corn bulbs in enclosed fixtures?
Yes — many of our models are specifically rated for enclosed fixtures and outdoor use (look for IP64 or “enclosed fixture rated” in the product description).

How much energy will I save?
Typical energy reduction is 60–80% compared with the HID lamp being replaced, plus additional savings from reduced maintenance and lower heat load on HVAC systems.

Are these dimmable?
Most LED corn bulbs are non-dimmable. A few selectable models offer step-dimming. Check individual product pages for dimming capability.

Do you offer bulk or project pricing?
Yes. Contact us or create an account for volume discounts on cases and large projects.
