FAQ's

A: LED corn lamps are a type of high-output retrofit lighting solution named for their resemblance to an ear of corn. They feature rows of LED chips arranged around a cylindrical core, providing omnidirectional (360°) light distribution. This design allows them to efficiently replace traditional HID lamps such as metal halide, high-pressure sodium (SON), or compact fluorescent lamps (CFL) in various commercial and industrial applications.

Internally, these lamps operate with integrated LED drivers that convert mains electricity into a regulated output suitable for powering the diodes. The LEDs produce instant full brightness with no warm-up time, while consuming significantly less power and producing less heat. As a result, LED corn lamps offer an energy-efficient, low-maintenance alternative for large-area lighting requirements such as warehouses, street lighting, sports halls, and outdoor floodlights.

A: Yes, many LED corn lamps are specifically designed for use in enclosed fittings, provided they have appropriate heat dissipation and are rated with an IP65 (or higher) ingress protection rating. Enclosed fittings are common in both indoor and outdoor environments, particularly in weather-exposed areas or industrial applications where durability and protection from dust or moisture are essential.

However, it's crucial to check the manufacturer’s specifications before installation, as not all corn lamps are suitable for enclosed spaces. Some lower-spec models may overheat if airflow is restricted, leading to reduced lifespan or performance. LampShopOnline clearly labels enclosed-rated models in our product listings, and our team is available to guide you in selecting the right lamp for your specific fitting and usage environment.

A: Switching to LED corn lamps offers a range of benefits, primarily in terms of energy efficiency, longevity, and brightness. These lamps consume up to 70–80% less electricity than traditional HID or CFL alternatives while delivering the same or higher levels of illumination. This leads to substantial cost savings on energy bills and a reduced environmental impact due to lower carbon emissions.

In addition to energy savings, LED corn bulbs have an impressive lifespan,typically 25,000 to 50,000 hours, which drastically reduces maintenance and replacement cycles. They also provide instant-on lighting with no flicker or warm-up time, making them ideal for settings where reliability and consistent output are crucial. Their solid-state design is more resistant to shock and vibration, which adds to their suitability for high-demand or outdoor environments.

A: Choosing the right LED corn lamp depends on several key factors including wattage, base type (E27, E40, B22), size of the fitting, IP rating, and whether the lamp is compatible with enclosed fixtures. The first step is to assess the lighting requirements of your space, consider the ceiling height, desired brightness (lumens), and the existing fitting dimensions. Corn lamps range from compact 20W models to high-powered 100W+ lamps, replacing traditional lamps from 70W to over 400W.

You should also confirm the type of lampholder in your existing fitting. Many industrial or streetlight fixtures use an E40 base, while smaller or domestic fittings may use E27. For outdoor or damp environments, opt for lamps with IP65+ ratings. If you're replacing a SON or metal halide lamp, check whether your existing ballast needs to be bypassed. At LampShopOnline, we provide detailed product filters and specifications to help you select the perfect lamp for your needs.

A: In many cases, LED corn lamps are designed as a direct retrofit for SON (high-pressure sodium) and metal halide lamps. They match the brightness levels while using a fraction of the power and offering a much longer operational life. Retrofit installation is often straightforward, simply remove the old lamp and install the new LED corn lamp into the same fitting, assuming the fitting supports the lamp’s dimensions and base type.

However, one key consideration is the existing ballast. Most LED corn lamps are designed to work on direct mains voltage (typically 240V) and may require you to bypass or remove the existing ballast to prevent electrical conflicts. This is especially true for fittings previously running on discharge technology. Always consult the installation guide or a qualified electrician when retrofitting to ensure a safe and compliant upgrade. LampShopOnline also offers ballast-compatible models where available for easier conversion.
