NLPIP Specifier Reports: Streetlights for Collector Roads

The National Lighting Product Information Program (NLPIP) at Rensselaer Polytechnic Institute's Lighting Research Center (LRC) purchased 14 streetlights, identified by a specifier survey, between July and October 2009. Four used high pressure sodium (HPS), one used induction, eight used light-emitting diodes (LEDs), and one used pulse-start metal halide (PSMH) light sources. NLPIP determined how many of each type of streetlight were needed to illuminate 1.0 mile (1.6 kilometer [km]) of a collector roadway to meet the design criteria specified by the American National Standards Institute (ANSI)/Illuminating Engineering Society of North America (IESNA) RP-8-00 (R2005), the American National Standard Practice for Roadway Lighting (referred to as RP-8 below). NLPIP then calculated power demand and costs per mile.
