Why should I use LED corn bulbs?
Did you know that the LED corn lights can replace metal halide or high-pressure sodium lights in outdoor or industrial settings, such as in parking lots and warehouses? LED corn bulbs can retrofit high bay and low bay lights and offer many wattage options. Corn bulbs retrofit into existing metal halide or high-pressure sodium fixtures without needing to replace the entire fixture.
The LED corn light bulb offers higher energy efficiency for lower replacement and maintenance costs. The bulb uses a plastic cover that protects both the driver and led lights from bugs, dust, weather, and heat. Due to the large surface area of their aluminum structure, heat can easily escape. These low-voltage bulbs offer a lifespan up to five times longer than traditional bulbs. The LED corn light bulb also offers durability, a 360-degree beam angle, and instant-on options.
Where can I use Corn bulbs?
Corn bulb lighting works for indoor and outdoor commercial applications including the following:
These lights install on ceilings between 20 to 45 feet high. High bay corn bulbs give off 10,000 lumens or more. They use beam angles of 60, 90, or 120, which helps the lamp create a focused beam with a high lux level.
What type of light do Corn Bulbs emit?
PLED corn lamps also known as corn lights emit bright light that resembles a very warm white light of light. The type of light they emit depends on the specific LED chips used in the corn cob lamp. The bulbs are currently available on the market in a vast color temperature range.
Corn lights can emit a near daylight white light or a cozy yellowish light. That’s often associated with traditional incandescent light bulbs. They also create a warm white light resembling a comfortable and inviting atmosphere, making them suitable for indoor spaces like living rooms and bedrooms.
These lights install on ceilings lower than 20 feet high. They give off a lumen count less than 10,000. A low-bay corn bulb uses a beam angle of 120, which spreads the light to maintain the desired level.
Known for their “cobra head” or “shoebox” design, these lights install in outdoor areas illuminating highways, streets, parking areas and more.
Outdoor lights install in a broad area such as parks and playing fields. The high lux and lumens output make this type of lighting perfect for sporting events.
Shop lights install in workshops or mechanic shops to provide light for specific tasks. These lights also supplement natural or overhead light.
Typically found along walkways and parks, these lights rest at the top of a pole of some sort.
The Life Span of a Corn Led Bulb
Led Corn Light bulb bulbs lifespan can vary depending on various factors including their quality, usage and operating conditions.
Unlike traditional incandescent or fluorescent light bulbs, LED bulbs produce very little heat making them more energy efficient. This efficiency is a main contributor to their extensive lifespan and reduced energy consumption.
LED corn cob lighting has quickly become a great alternative for lighting for users mainly due to its long lifespan. Not to mention its reduced maintenance requirements and ability to lower utility costs.
Corn lights use extensive lighting technology that eliminates energy wasting and helps users to save money. Generally, good-quality LED corn light bulbs are designed to last anywhere from 25,000 to 50,000 hours. Their design helps them to hone a long lifespan compared to other types of bulbs like the incandescent bulbs, lights etc.
The Many Uses of Corn Cob Led Bulbs
The versatility of corn LED bulbs, along with their energy efficiency and long lifespan, makes them suitable for a wide range of lighting applications including commercial and industrial applications, indoor applications and more. To operate as a versatile lighting solution that can cater to users who are looking to optimize their light output, A corn lamp ultimately uses the following lighting technology:
Outdoor Lighting: Corn Cob lamps are often used for outdoor area lighting in parking lots, streetlights, and pathways because they offer an omnidirectional lighting design that provides even illumination enhancing safety and visibility.
Warehouse and Industrial Spaces: These bulbs are ideal for lighting large indoor spaces such as warehouses, factories and industrial facilities due to their high brightness and wide beam angle illumination capabilities.
Post Top Lighting: Commonly seen in parks, public spaces, and residential neighborhoods, corn cob lamps in post top fixtures offer aesthetically pleasing and efficient lighting for outdoor areas.
Street Lighting: Corn Cob LED lights are being adopted for street lighting due to their long lifespans, reduced maintenance requirements and energy efficiency.
What wattage and lumen count do I need?
LED bulbs offer the same brightness as metal halide or high-pressure sodium bulbs at a much lower wattage. Lumen refer to the brightness of the bulb, while wattage refers to the energy the bulb uses. When replacing metal halide lamps, look at the lumen outputs:
| Metal Halide Wattage | LED Corn Bulb Equivalent |
| 400W | 12,000-18,000 |
| 250W | 9,000-12,000 |
| 150-175W | 7,000-9,600 |
| 75-125W | 4,000-8,000 |
Switching to LED lowers your wattage, and therefore, your energy bill, without lowering the brightness.
Additionally, LED corn lamps come in a wide range of color temperatures suited to different situations.
- 3000K: Warm white color, best for living rooms, kitchens, and bedrooms
- 4000K: Natural white light, best for offices and overhead lights
- 5000K: Cool daylight, best for basements and garages
While LED corn lights come in all these options, the majority go in the 5000K range due to their industrial or outdoor location.
How to install the LED corn bulb?
