    Discover the Advantages of Corn Cob LED Retrofit Lamps

    Ready to upgrade to the newest, most energy-efficient lighting technology? Keystone's LED Wattage Adjustable & Color Tunable Corn Cob Retrofit Bulb will not let you down. It is a great alternative to lower utility costs than using a traditional metal halide bulb. There is also less maintenance required than standard metal halide bulbs. This bulb is IP64 rated, UL listed, and RoHS Compliant as well. Making adjustments on the job is easy with the power selectable and color selectable feature. With three wattages and three color temperatures to choose from, this LED lamp becomes 9 bulbs in 1!

    This LED corn cob retrofit light bulb is a great HID replacement LED option with over 50,000 hours of LED life. It is an environmentally friendly choice that is both more energy efficient and there is no mercury used in the bulb. It is instant on and has an integral driver that includes 4kV surge protection. There is no need for an external driver or ballast. This corn cob bulb is also suitable for use in a fully enclosed fixture to provide omni-directional lighting for wall packs, canopy fixtures, and shoebox fixtures. The ballast needs to be disconnected but the existing fixture can be reused. The minimum lamp compartment dimensions are 8" x 8" x 9".

    This lamp should not be used with standard dimmers. It is not compatible with phase dimmers. If dimming functions are wanted, the below are sensors that can be purchased separately:

    • LEDSNSR1000051501 - LED Microwave Occupancy Sensor - 12V Input - Keystone
    • LEDSNSR1000051502 - LED PIR Occupancy/Daylight Sensor - 12V Input - Keystone

    Additionally, there is a photocell daylight sensor (LEDSNSR1000051503) that can be purchased separately and installed to the top of this bulb. The operating temperature includes −40°F/−40°C to 140°F/60°C.

    What are LED corn bulbs used for? What are some advantages of replacing metal halide lamps with corn cob bulbs?

    LED Corn Cob retrofit bulbs are typically used to replace traditional metal halide lamps. They pack a bright lumen output in a compact bulb for energy savings and more energy efficiency. Because they are compact, these bulbs can fit into the tightest of fixtures including wall packs, canopies, and shoebox lights.

    Are LED corn light bulbs dimmable?

    It depends on the specifications of the LED Corn Cob bulb. This particular LED Corn Cob bulb is non-dimmable. It should not be used with standard dimmers and is not compatible with phase dimmers.

    Dimming functions are available with the following sensors (sensors can be purchased separately):

    • LEDSNSR1000051501 - LED Microwave Occupancy Sensor - 12V Input - Keystone
    • LEDSNSR1000051502 - LED PIR Occupancy/Daylight Sensor - 12V Input - Keystone
