Keystone Technologies delivers improved performance and increased savings with the new KT-LED54HID-EX39-8xx-D LED Corn Lamp. This 54 Watt LED Lamp delivers light and is designed to replace a 250 Watt metal halide. The internal driver eliminates the need for an external driver or ballast, allowing users to install this lamp directly into existing fixtures. An integrated heat sink efficiently dissipates heat and guides intrusive water out of the lamp. Utilizing the innovative SmartCool technology, a thermal sensor in the lamp activates during extreme heat conditions. Power to the lamp is reduced by up to 20% to cool the lamp and extend lifespan. Once this sensor reaches an acceptable temperature, the lamp returns to full light output.
