An LED corn bulb, is also known as a corn lamp or corn light. These lights are designed to provide high efficiency lighting for certain indoor and outdoor applications. Specifically, the bulbs are used in high bays, post lights, and other typical HID fixtures. The Straits Lighting Beam 360 LED Corn Lamp is an excellent replacement for metal halides, high-pressure sodium lamps, and CFL bulbs. Our bulbs have shatterproof construction and high efficiency LED chips which ensure a long lifespan. Beam 360 Corn Lamps are approved for use in enclosed fixtures thanks to the patented heat dissipation system. If retrofitting HID fixtures, existing ballast must be bypassed.
