What are LED Corn Bulbs?
A: These bulbs are called corn cob bulbs because of their design. Inside the glass tube you'll find rows of square LEDs arranged like the kernels, on a corn cob. The number of LEDs can vary from 80 to over 100 depending on the wattage and model. When lit up together they emit an uniform light. LED corn bulbs are specifically designed to replace High Intensity Discharge (HID) lighting such as metal halide and high pressure sodium lamps. Their high lumen output makes them perfect for spaces like warehouses, gymnasiums, parking garages and more. Unlike HID lamps that have a hue LED corn bulbs produce white light. Moreover thanks to the efficiency and long lifespan of LEDs they offer energy savings compared to lighting solutions.

With their appearance and impressive performance LED corn bulbs are a choice, for illuminating large scale areas.
Why Are Corn Bulbs So Popular?
A: The rising popularity of LED corn bulbs has been quite remarkable, in times. Its easy to see why. One of the advantages is their installation process. Simply screw them in like a regular bulb and you're good to go. Moreover they offer brighter and evenly distributed lighting compared to traditional incandescent bulbs.
Furthermore LED corn bulbs are cost effective due to their energy consumption, which translates into savings on your electricity bills. Additionally with a lifespan of up to 25 years they also save you money on replacements well. These LED bulbs are designed for durability without any filaments or glass components that can easily break.

Did you know how long does an LED bulb last before losing light? Answer: 6000 Hours! An incandescent bulb lasts just 1500 hours total. An good LED will not lose 1% of its light before 6000 hours. That's a BIG upgrade
What is the difference between E26 and E39?
A: LED corn bulbs come with one of two base types:
E26 - The E26 base uses the standard medium Edison screw base, the same kind found on a typical household light bulb. The "E" stands for Edison, while the "26" indicates a diameter of 26mm, or about 1 inch. E26 bases are used on LED corn bulbs designed to replace lower wattage metal halide and HID lights.
E39 - Also known as mogul or goliath Edison screw, the E39 has a base diameter of 39mm or about 1.5 inches. The larger size provides more stability for high powered, large corn bulbs designed to replace 150W+ HID lighting. E39 bases are commonly used in industrial and commercial applications.
When selecting an LED corn bulb, be sure to check the specs for the correct E26 or E39 base to match the fixture you'll be installing it in. The packaging or spec sheet will clearly indicate the base type. Choosing the right base ensures a proper fit and optimal light distribution.
How to Choose the Right Amount of Lumens?
A: When it comes to choosing an LED corn bulb it's important not to focus on the wattage. Instead pay attention to the lumen output. Lumens determine how bright a bulb appears and measure the light it emits. Watts on the hand only indicate the amount of power consumed.
LED bulbs are highly energy efficient which means that a lower wattage LED bulb can produce the even greater amount of light, as a wattage incandescent bulb. For instance a 100W LED corn bulb can emit over 10,000 lumens while a 100W incandescent bulb produces than 1600 lumens.
The key is to match the lumen output with your lighting requirements. In industrial spaces its generally recommended to aim for a minimum of 100 lumens per foot. Make sure to check the lumen specifications of any LED corn bulb you consider purchasing to ensure that it provides illumination for your areas size.
By prioritizing lumens over watts you'll be able to find an LED corn bulb that strikes the balance, between brightness and efficiency for your needs.
What is the Lumen Output for Common HID Replacements?
A: When transitioning from HID lighting, to LED corn bulbs it is recommended to follow these lumen guidelines:.
- For replacing 1500W Metal Halide, opt for LED bulbs with 60,000+ lumens using either 450W or 600W.
- For replacing 1000W Metal Halide choose LED bulbs with 38,000+ lumens using a 300W optionFor replacing 400W Metal Halide consider LED bulbs with a lumen range of 12,000 18,000. Opt for options between 100W and 150W.
- When replacing a 250W Metal Halide bulb, LED alternatives offering a lumen range of 9,000 to 12,000. Consider using either an 80W or a100W bulb.
- To replace the bulb opt for LED bulbs providing 7,000-9600 lumens. Choose options between 60 W and 80 W.
- Finally, to replace 75 W to 125 W Metal Halide bulbs, opt for LED alternatives offering 4,000 to 5,000 lumens .Consider using 40W and 60W options.
It is important to note that metal halide bulbs tend to lose brightness over time while LEDs maintain output for many years. Upgrading to LED corn bulbs enhances the quality of light. It also reduces the need, for maintenance.
What is the conversion LED from a 400 watt metal Halide
A: When replacing a 400W metal halide high bay fixture, an LED corn bulb or luminaire with 13,000 to 20,000 lumens is recommended.
Why this wide lumen range? Metal halide bulbs slowly lose brightness over time. A 18,000 lumen LED will match the light output of a brand new 400W metal halide. A 13,000 lumen LED will replicate the illumination of a 5 year old 400W metal halide that's dimmed with age.
Either way, choosing an LED in this 13,000-20,000 lumen range will provide similar or better light compared to an existing 400W metal halide setup. And the LED alternative will do it with superior efficiency, lower maintenance, and no hazardous disposal requirements. Making the switch to LED can quickly pay back through energy savings too.
"When converting from metal halide lighting, carefully compare lumen output to make sure your new LED corn bulb or fixture provides the right amount of bright, energy-saving illumination" - Bill G. General Manager at LEDLightExpert.com.

How to select Kelvin Color?
A: The corn bulbs are available in various colors. We offer you following colors in LED corn bulb:
3000K LED Bulbs
This provides a warm white color making it best suited for houses and restaurants. Creates a softer more relaxing environment
4000K LED Bulbs
This is a white natural light that is great for business are or other work areas. The reason is that it replicates the daylight.
5000K LED Bulbs
It is a white light that is great for large spaces and outdoors.
5700K LED Bulbs
It is a very cold color light that has a blueish tint to it. Look for them to draw attention in gas stations or retail
BELOW IS AN IMAGE OF WHAT KELVIN COLORS LOOK LIKE:
The American Medical Association advises against prolonged exposure to light over 5700K, as it can disrupt circadian rhythms and melatonin production. For health, use warmer 3000-5000K lighting where possible.
Outdoor lighting codes are also increasingly regulating color temperature, with many jurisdictions restricting lighting to 4000K or less to minimize sky glow.
Consider the intended application, ambiance, and health effects when selecting the right Kelvin temperature for your LED corn bulbs. In most cases, a warm to neutral white in the range of 3000K-5000K is recommended for optimal visibility, visual comfort and wellbeing.
How to Choose the Right Bulb Shape: 360 Degree vs Directional
A: LED corn bulbs come in two main shape options:
- 360 degree - These bulbs emit light in all directions, providing complete, uniform illumination. The omni-directional light works well with reflectors to distribute an even glow. 360 degree corn bulbs are a versatile and cost-effective choice for many indoor and outdoor spaces.
- Directional/Multi-faceted - Directional corn bulbs focus light downwards in a tighter beam spread. They contain internal facets that shape the light into a more focused spotlight distribution. Directional LED corn bulbs are ideal for targeted area lighting rather than general ambient illumination.
Consider your specific lighting needs. If you need wide, dispersed general lighting, a 360 degree corn bulb paired with reflectors is a good option. For more directed task lighting, a directional corn bulb with focused downward beam works better. Choose the shape that produces the optimal light pattern for your space and application.
Finding the Right Size Bulb
LED corn bulbs come in a range of sizes based on wattage and lumen output. Higher wattage bulbs produce more light, but require sufficient fixture space to allow for proper thermal management.
When selecting your bulb, be sure to carefully measure the available room inside your existing fixture. Compare this to the dimensions of the LED bulbs you are considering to ensure a proper fit.
Referencing product images can help visualize clearance. Look for specifications on the bulb's overall height and diameter. Also confirm whether the LED corn bulb has an integrated heat sink or external fins that require additional space.
Leaving a buffer of at least 3-4 inches around the bulb is recommended for optimal airflow and cooling. With measurements in hand, you can easily find an appropriately sized high-performance LED corn bulb that fits perfectly into your current fixture housing.
Are the bulb Rated for Enclosed Fixtures?
A: Yes, the majority of LED corn bulbs are designed and rated for use in enclosed fixtures. This means they can safely operate in covered housings that restrict airflow around the bulb.
When installing in an enclosed fixture, be sure to follow the recommended clearance guidelines to allow for sufficient ventilation and cooling. Leaving a few inches of space around the corn bulb can prevent issues with overheating.
However, very large high wattage corn bulbs above 200 watts, like 240watt and 300 watts are NOT enclosed. Their extreme brightness generates more excess heat, making an open fixture preferable.
Always verify the enclosed fixture rating to make sure your LED corn bulb can operate safely and reliably within a covered housing. Following bulb spacing and ventilation requirements will also help maximize the bulb's lifespan.
What voltages do the Corn Light bulbs work on?
A: LED corn bulbs must be matched to the correct input voltage for your electrical system. Standard voltage bulbs operate on:
- 120V
- 208V
- 220V
- 240V
- 277V
High voltage bulbs are designed for applications using:
- 240V
- 277V
- 347V
- 480V
Always verify the input voltage rating on the LED corn bulb meets your specific voltage. Trying to operate a bulb at the wrong voltage can result in light flicker, premature failure, or dangerous conditions. Properly matching the voltages will ensure safe, bright and reliable performance from your new LED corn bulbs. Consult a qualified electrician if you are unsure of your fixture voltage.
Choosing the ideal LED corn bulb for your specific needs may seem complicated at first glance. But by taking the time to carefully consider base types, lumen output, beam shape, color temperature and other factors, you can narrow down the perfect option for your space and application.
The right LED corn bulb will slot seamlessly into your existing fixtures, provide ideal light quality and distribution, and operate safely for years to come. And you'll enjoy major improvements in efficiency, brightness and maintenance versus outdated HID lighting.
With this guide's tips in mind, you can select a top-performing LED corn bulb tailored to your installation requirements. We offer a wide selection of durable, long-lasting corn bulbs suitable for enclosed fixtures in both indoor and outdoor settings.
