Keystone LED Corn Lamps allow you to easily upgrade inefficient HID fixtures with LED technology. The KT-LED27HID-E26-850-D-G2 LED lamp delivers 3,915 lumens of daylight 5000K white light while only operating at 27 watts. You can simply bypass the existing ballast and connect the 120-277V power feed directly to the socket. Utilizing its integral driver, it eliminates the need for an external driver or ballast. It has a built-in heat sink that allows it to quickly dissipate heat and guide water intrusion out of the lamp. This LED lamp also features SmartCool technology, a thermal sensor in the lamp activates during extreme high temperature conditions. Power to the lamp is reduced by up to 20% to cool the lamp and maintain lamp life. Once the sensor reaches an acceptable temperature, the lamp gradually returns to full light output.
