What Is an LED Corn Lamp and How Does It Work?

An LED corn lamp is a type of energy-efficient lighting designed to replace traditional high-intensity discharge (HID) lamps. Its shape and multiple LED chips resemble corn kernels, offering 360-degree illumination.

Where Can LED Corn Lamps Be Used?

LED corn lamps are versatile and can be used in street lights, industrial high bays, floodlights, bollards, car parks and many other application areas, offering a cost-effective upgrade for most E27/E40 fittings.

How Do I Install an LED Corn Lamp Safely?

To install an LED corn lamp safely, switch off the power, remove or bypass any ballast, check fixture compatibility, and follow the manufacturer’s instructions. We recommend using a qualified electrician for installation.

Are LED Corn Lamps Suitable for Enclosed Fixtures?

Not all LED corn lamps are suitable for enclosed fixtures. Always check the lamp’s specifications to ensure it’s rated for enclosed or semi-enclosed use.

How Do I Choose the Right Wattage and Lumens for My Application?

To choose the right wattage and lumens for an LED corn lamp, match the lumen output to your lighting needs and consider the lamp it’s replacing. Higher wattage equals more lumens, but always prioritise lumen output over wattage.
