Maximize efficiency with LED replacement bulbs for HID fixtures.

Menu

Keystone DirectDrive LED HID replacement lamps are the ideal way to upgrade existing HID fixtures to the latest in LED technology. Simply bypass the existing ballast by cutting the wires and connecting the 120-277V line voltage directly to the sockets. No ballast or external driver is required. These vertical corn cob LED lamps feature a 360° beam angle to produce omni-directional light output.

Choosing LED replacement bulbs for HID fixtures is an easy way to increase lighting efficiency. Corn cob LED lamps use significantly less wattage to deliver comparable lumens as conventional metal halide lamps. Keystone’s LED HID replacements also provide better color rendering than metal halide lamps.

Extend the life of LED HID replacements with SmartCool

With SmartCool technology, a thermal sensor in the lamp activates during extreme heat conditions. Power to the corn cob LED is automatically reduced by up to 20% to cool the lamp down and maintain lamp life. Once the sensor reaches an acceptable temperature, the lamp will gradually return to full light output. This is all done within the lamp, requiring no effort on your part! SmartCool is included in 54W, 63W, 80W, 100W, and 115W DirectDrive LED HID lamps.
