If you are in the process of updating your outdoor lights, you've most likely considered using LED corn bulbs.
Being one of the most efficient of LED lights because of its multidirectional light distribution, the LED corn cob bulbs is a favorite amongst landscape contractors.
Although installing the cob light bulb is as easy as screwing in any light bulb, choosing the right corn bulb should be done carefully.
In this short article, we've gathered the most important things to consider before buying your corn cob light. If you already know what you are looking for, head over to our LED Corn Bulbs category and find your fixture.
Lumens measure the total amount of visible light. Visible light is the light that can be seen by the human eye. The higher the lumen rating of a bulb, the brighter it appears. The brightness of traditional lighting systems is measured in watts because they use a lot of electricity. The more energy they draw, the more light they produce. But since watts measure energy usage and not light output, we no longer rely on them to know how bright a LED bulb is.

2. Beam Angle
The beam angle is the angle at which light is distributed. Every light source has a beam angle, from a candle to a LED light. Traditional lights and LEDs have a variety of beam angles, from 4° to 120°. When you choose a light bulb with a wider beam angle, it doesn't mean that you get extra light, it just means that the light is spread out further.
The brightness of the light, which is measured in lumens, will remain the same but the beam intensity, which is measured in candelas, will increase. The biggest shortcoming of choosing a wider beam angle is that it is not very intense and the midpoint of the light beam won’t go very far.
Luckily, we've built our corn bulbs with a luminous front which creates a omnidirectional beam angle. In other words, there's no need to worry about the beam angle since our corn bulbs beam angle is 360°.
3. IP and UL Ratings
IP, which stands for Ingress Protection, is an International Protection Marking that indicates the degrees of sealing effectiveness provided by electrical enclosures against the intrusion of water, dust, and accidental contact.
The letters “IP” are usually followed by two numerical values: the first indicates protection against intrusion while the second indicates protection against moisture. LED corn bulbs that are used in wet environments have IP65 to IP68 ratings.
UL, Underwriters Laboratories, also gives ratings to lighting fixtures used in wet environments. UL gives two ratings for these lighting fixtures: UL listing for damp locations (damp rated) add UL listing for wet locations (wet rated).
Damp locations are interior or exterior locations that are continually or periodically subjected to moisture. Wet locations are places where water and other liquids splash, flow, or drip against or on the electrical components of lighting fixtures.
4. Correlated Color Temperature
Color temperature describes the light appearance of a light bulb. It allows us to know how the light produced will look and feel. The Kelvin scale is used to measure color temperatures. Temperatures for residential and commercial lighting applications fall between 2000K and 6500K. Warm white color temperatures are between 2000K and 3000K, cool white temperatures fall between 3100K and 4500K, while daylight temperatures start from 4600K to 6500K.
Warm white light has an orange to yellow-white appearance (like that produced by high-pressure sodium lamps). Cool white light is neutral white and may have a slight blue tint. Daylight light is blue-white light that mimics the light produced by the sun at noon. The color temperature of light determines the mood of a space and can influence work performance and buying behavior.
For LED corn bulbs, higher CCT is often preferred as they are usually installed in areas where the focus of the light is to increase safety and sight. Therefore 5000K corn bulbs are great for places such as warehouses, arenas, parking lots and similar.
5. Color Rendering Index
The Color Rendering Index (CRI) describes how a light bulb makes the colors of objects appear to human eyes and how well it reveals slight differences in hues. It is a scale with digits ranging from 0 to 100 that indicates how good an artificial light is at rendering colors compared to an ideal light source such as sunlight.
Generally, the higher the color rendering index of a light source, the better its color rendering ability. Most LED corn lights have a color rendering index of 80 and above. All Hyperikon LED Corn Bulbs have higher than 84+ in CRI, render colors perfectly and are used for tasks that require faultless color discrimination.
6. Quality Construction
Last but most important is the build of the fixture. Just like lighting sources vary, LED corn cob bulbs are not equal. Some have better construction and components compared to others. High-quality LED lights usually have the following components:
- Optics: These evenly distribute the light and are normally made from plastic to minimize the chances of shattering.
- LED Chips: These small yellow pieces create the light and are usually attached to a metallic piece.
- Heat Sinks: These dissipate the heat produced by the LEDs while they are in operation. A heat sink provides the path for heat to travel from the bulb to the outer environment.
- Drivers: Also known as circuit boards, the drivers pull power from the sockets and tell the LEDs to switch on, switch off, change color, or dim.
- Housing: The housing for a LED light must be conductive to heat as the driver usually heats up when power passes through it.
- Base: LED corn lamps can be used in most screw-in sockets. When buying these lamps, be sure to choose the right base. There are LED corn lights for E26 and E27 base bulbs (Medium Edison Screw), and E39 and E40 base bulbs (Mogul Edison Screw).
LED lights have overtaken traditional lighting systems in the short time they've been around because of their lengthy lifespans, low-maintenance requirements, and reduced energy consumption. The Department of Energy estimates that by 2027, the extensive use of LEDs will save approximately 348 TWh of power, which translates to $30 billion (going by today's electricity prices).
