LED HID Retrofit Bulb, 27 Watt, 3915 Lumens, Ballast Bypass

Keystone LED HID retrofit bulbs allow you to easily upgrade inefficient HID fixtures with LED technology. This LED HID retrofit bulb delivers 3,915 lumens of light output 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 HID retrofit bulb 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.
