Upgrade your post tops and bollards with corn lamps for a cost saving solution.

Are you in need of a quick and easy solution to convert your outdoor lighting to energy-efficient LEDs? Look no further than LED Corn Lamps. These bulb shaped lamps are packed with hundreds of individual light-emitting diodes(LEDs) that are all fixed to a metal heat-dissipation element. At up to 75% more efficient than metal halide, high-pressure sodium, or incandescent bulbs, corn lamp are becoming an obvious solution for those looking to retrofit their lighting with efficient LEDs.

So what are corn lamps?

yellow corn on the cobA corn lamp is an assembly of light-emitting diodes(LEDs) on a metal structure. They are called a corn lamp because the yellow LEDs resemble corn kernels on a corn cob. Corn cob lamps are meant to provide a large amount of light while using LEDs, which requires a large amount of diodes. The diodes(sometimes hundreds) are mounted to a metal "cob" that has as much surface area as possible to keep the diodes cool.

 

What kind of fixture will accept corn lamps?

Many screw-in sockets will accept a corn lamp, but you will have to make sure you have the right one. There are corn lamps for E40, E27(Edison), mogul(E39, and medium(E26) base, and more are being developed everyday.

 

How do I install corn lamps?

What should I look for in good corn lamps?

Cooling

3bl corn lamp 6063 aluminum cooling structureA good corn lamp should cool itself with an aluminum structure with lots of surface area to let the heat escape. Some corn lamps have fans and while this sounds fancy, they are problematic and cheap ways to make a corn lamp. The fan's motor will die out long before the LEDs fade, if the fan is not stopped by insects or dust before then. The image to the left shows a corn lamp from manufacturer, 3BL. The compex structure of 6063 aluminum will dissipate the heat better than a fan would. This is a high-quality corn lamp!

 

LED Quality

Protective Covering

In order to provide proper performance of the LEDs ove time, a transparent plastic covering should cover the diodes to protect them from dust and insects. This will keep the light quality from diminishing over time.

 

Certifications

Design Lights Consortium(DLC) - An independent testing agency that offers DLC certification for those products that pass their stringent guidelines for energy-efficiency. You can search for products that have passed by part number on their website.

Underwriter Laboratories(UL) - This global safety science comapny tests all consumer products for safety and awards their UL logo to products that meet their standards. This certification is particularly important in lighting since the hazard of a low-quality lamp could be a fire. Learn more about UL here.

Lighting Facts - A program started by the U.S. Department of Energy produces a standardized label for lgihting products that resemble Nutrition Facts that are seen on food products. This makes it easier for consumers to compare and evaluate two lighting products side-by-side.

What kinds of bulbs can I replace with corn lamps?

corn lamp bulb replacementsJust about any bulb with a matching base. The most important thing to check is that your corn lamp will fit in your luminaire with the cover on it. You can check product dimensions on every product page of the Shine Retrofits website.

 

Can I mount high wattage corn lamps horizontally?

These lamps do get heavier as they go up in wattage, and sometimes will be too heavy for the screw socket that they fit in. If you mount the bulb vertically(up or down), they will work just fine. However, if you have a horizontal socket, you may need to install a thin wire to support the bulb and reduce stress on the socket.

 

What corn lamps does Shine Retrofits recommend?

The quality of the products from 3BL LED impress us consistenly. They manufacture a full range of corn lamps between 18 and 100 watts(capable of replacing HIDs between 50 and 400 watts). Click below to see all 3BL corn lamps.
