LED Corn Light Bulb Buyers Guide (2024)

A: There are 2 base types for corn bulb: E26 and E39. Here is how to find the correct base for you;
• E26 Base Bulbs: This is called as Medium Edison Screw or one-inch Edison Screw. It is the standard base for most of the bulbs. “E” stands for Edison, while 26 indicates the diameter of the base in mm. E26 is the standard base for 120-volt bulb, which is why they are mostly found in homes. See E26 base corn cob bulbs here.
• E39 Base Bulbs; It is normally referred as Mogul Edison Screw a sometimes known as Goliath Edison Screw. Similarly, the “E” stands for Edison and 39 is the diameter of the base. They are special because of their wide usage in industrial or farm applications. They are mostly used in higher output bulbs of 150 watts HID and higher such as factories, roads, and warehouses. They are 1.5 inches in diameter and are clearly larger than E26. See E39 corn cob bulbs here.

A: One of the important things to consider when buying a corn light is the lumens. This is the amount of light that the bulb produces, which is different from watts. Watts measure the energy that the bulb consumes and indicate how bright the bulb would be. However, as LEDs have become more efficient, lumens are a better way to compare the brightness of different bulbs. A lumen is a unit that measures the brightness of the LED bulb. So when you are shopping for LED corn bulbs, you should focus on lumens instead of watts.

To give you some reference points, you should select 800 lumens for a 60 watt bulb or 1000 lumens for a 75 watt bulb. For outdoor security lights, you should choose 2500 to 6000 lumens for smaller spaces and higher lumens for bigger or commercial spaces. For replacing metal halide bulbs, you should use the interchange chart that can be found below.

A: If you want to replace your HID or metal halide bulbs with LED lights, you need to consider the lumen output and the wattage of the LED products. Lumen output is the measure of how much light a bulb produces, while wattage is the measure of how much energy it consumes. LED lights are more energy-efficient and durable than metal halide bulbs, which lose up to 75% of their lumen output over five years. Here are some guidelines for choosing the right LED replacement for different wattages of metal halide bulbs:
• For 1500-watt metal halide bulbs, you need at least 60,000 lumens of LED light. You can choose a 500-watt LED fixture for lower installations or a 500-watt stadium light for higher installations.
• For 1000-watt metal halide bulbs, you need at least 40,000 lumens of LED light. You can choose a 300-watt LED bulb, fixture or retrofit kit. However, note that the 300-watt bulbs are not rated for enclosed fixtures, so it is better to opt for a fixture in this case.
• For 400-watt metal halide bulbs, you need between 12,000 and 18,000 lumens of LED light. You can find a fixture in this range or visit our [100 watt and up Corn light page]. There you will see bulbs of 100 watts, 120 watts or 150 watts. These are all common replacements for this wattage.
• For 250-watt metal halide bulbs, you need between 9,000 and 12,000 lumens of LED light. The popular choice is an 80-watt LED corn bulb, but you can go for a 100-watt one if you want more brightness.
• For 150-watt or 175-watt metal halide bulbs, you need between 7,000 and 9,600 lumens of LED light. The best option is a 60-watt or an 80-watt LED corn bulb.
• For 75-watt or 125-watt metal halide bulbs, you need between 4,000 and 8,000 lumens of LED light. The ideal choice is a 40-watt or a 60-watt LED corn bulb.

A: To replace a 400 watt metal Halide we recommend from 13,000 lumens to 20,000 lumens. Metal halide starts out very bright but then loses 70% of its light output. An 18000 lumen bulb or fixture will feel like a 400 watt metal halide after about 6 months. A 13,000 lumen LED bulb or Luminaire will feel like a 5 year old 400w metal halide bulb.

A: LED corn bulbs come in different color temperatures, measured in kelvins (K). The color temperature affects the appearance and mood of the light. Here are the differences between the common color temperatures for LED corn bulbs:
• 3000K LED Bulbs: This color temperature produces a warm white light that is best suited for homes and restaurants. It creates a cozy and relaxing environment.
• 4000K LED Bulbs: This color temperature produces a natural white light that is great for offices and other work areas. It provides a clear and bright illumination.
• 5000K LED Bulbs: This color temperature produces a pure white light that is great for large spaces and outdoors. It mimics daylight and enhances visibility.
• 5700K LED Bulbs: This color temperature produces a cool white light that has a bluish tint to it. It is ideal for attracting attention in gas stations or sinage, but should be used with caution.

A: There are many types of LED corn bulbs when it comes to shapes. Some popular choices are round or flat. One offers 360 degrees of light, whereas the other offers 180 degrees. People are often confused which type of bulb to buy. We are here to help you make the decision easily. The flat bulb that offers 180 degrees of light provides light that is focused downward. On the other hand, the corn bulb that offers 360 degrees of light is better. They provide light in all the directions and are more cost effective. With the help of a reflector, you can even out the light of the bulb. They are the best choice for many outdoor and indoor applications.There are many types of LED corn bulbs when it comes to shapes. Some popular choices are round(360degree), downlight or flat. One offers 360 degrees of light, whereas the other offers 180 degrees. People often wonder which type of bulb to buy. The flat bulb and down bulb offers 180 degrees of light, with the difference being where the socket is. Both 180 degree bulbs provide light that is focused in just one direction, which can be more efficient. This may be suitable for some applications, such as ceiling lights or wall sconces. On the other hand, the corn bulb that offers 360 degrees of light is more versatile. They provide light in all directions and are more cost-effective. With the help of a reflector, you can even out the light of the bulb and avoid glare or shadows. They are the best choice for many outdoor and indoor applications, such as high bay lights, post tops or barn lights.

A: Yes, most of the LED corn bulbs are enclosed rated. That means they can go inside a fixture that closes up or is enclosed.Our bulbs are rated as safe to be used in the enclosed fixtures for both commercial and industrial applications. You just have to keep in mind that you should leave some space around the bulb for cooling.Note that the some versions of the very large bulbs of 200watt, 240watt and 300 watts are NOT enclosed rated.They need to go in open fixtures. Check the specs as each series will be different.

A: Like all electrical items, an LED Corn Light bulb has to have the compatible voltage of the building.An LED corn bulbs work from 90 to 277V AC in standard voltage version or from 200 to 480vac in high voltage.Here are some common voltages that the corn bulbs can be used in. Standard Voltage will work on;

• 120 volts,
• 208 volts,
• 220 volts,
• 240 volts,
• 277 volts

• 240 volts
• 277 volts,
