What are Corn Bulbs?

This is a question many people ask when they first start looking at LED light bulbs. In the simplest terms, these bulbs got their name because they actually look like corn on the cob. Instead of one large bulb, as you had with traditional incandescent lights, the LED corn light is composed of several lines of small, square diodes on every side of the base tube.

Generally, you’ll find from 80 to 108 of these individual light diodes, which makes them a great replacement for your HID and metal-halide bulbs. People have found they are just right for almost all locations, including high-bay lighting, street lights, and for illuminating parking lots. Obviously, these lights have become very popular because residential and commercial customers have found LED light bulbs so easy to install, to mention one key benefit.

But, there are other reasons for choosing the LED corn light. This design not only provides outstanding illumination it delivers unmatched efficiency. You’ll save a lot on energy costs and maintenance/labor costs, because LED technology performs about five times as long as classic lighting.

Important Details

Correct base: As you work with your supplier of LED light bulbs, you’ll learn how important it is to select the correct base for you corn bulb. There are two types: E26 and E39. You may read about or hear about the “medium Edison screw” or “one-inch Edison screw” when shopping for lighting. This is widely considered the standard for bulbs, including the 120-volt bulb used in most homes.

The E39 base or “mogul Edison screw” is often used in farm applications and industrial locations, such as factories and warehouses. These bulbs are generally 250W.

Lumens: As you search for the correct LED corn bulb, be sure to pay as much attention to lumens as you do to watts. Watts measure the amount of energy being used and does have some connection to how bright the bulb will be. However, with LED light bulbs, brightness is measured in lumens. For example, if you’re replacing a 175-watt metal halide bulb, look for 7000 to 9000 lumens. This will help you select the 60-watt to 80-watt corn bulbs.

Other examples: 250-watt metal halide, use 9000 to 12000 lumens, which will be delivered by the 80-watt and 100-watt bulb. For the 75 to 125-watt metal halide, 4000 to 8000 lumens is sufficient. Use the 40 to 60-watt corn bulb. 

Color, Voltage and More

You should also discuss color and voltage when you talk with your lighting expert about the LED corn bulb. Consider 3000K, 4000K, and 5000K bulbs. The lower number indicates softer, more relaxing lighting, great for homes and restaurants. The second, 4000K, can replicate daylight and will be outstanding for work areas in your business. When you select the 5000K color level, you’ll probably be serving large, open spaces and outdoor settings.

It’s also important to select your corn bulbs based on voltage, as you learned when looking at lumens. For safe, comfortable use, consider lights ranging from 120 volts to 277 volts. It’s important not to use high-voltage bulbs in 480-volt fixtures.  

Here are a few other important details. You’ll find this information very useful in your search for the right LED corn light. Ask your lighting specialist about fitting the bulb properly to your fixtures. You can use LED bulbs in enclosed fixtures safely, in almost every setting.

One more decision to make: Choose from two types of LED corn bulb. One provides 180-degrees of lighting, while the other offers 360-degree illumination. The first will often be used when the light must be focused down. The second provides lighting in all directions and should prove to be the cost-effective choice.


When you take a bit of extra time to select your LED corn light, you’ll enjoy the right fixture and the most comfortable lighting for your space. If you want bright, outdoor lighting, this is also a fine option. Use the valuable information in this guide to help you select the right corn bulbs for your specific location.
