A new report from the Lighting Research Center* at Rensselaer Polytechnic Institute focuses on the benefits from switching to LED lighting technologies There is a rapidly changing landscape for roadway lighting worldwide, largely due to the widespread acceptance of light-emitting diode (LED) technology. In developed markets such as the US, this has opened up a universe of new possibilities regarding LED replacement lamps. There are 144 million high-intensity discharge (HID) lamps in the US, representing
