Left Atlantic City���s historic four-mile boardwalk is purportedly the longest boardwalk in the world. The seaside resort still attracts some 30 million visitors each year. Because some of the sand dunes rise above the height of the boardwalk, the double-head, acorn-shaped lowpressure sodium fixtures created a sort of tunnel effect. The lighting was ���romantic,��� but not dark-sky friendly, and didn���t engender safety. Also, about 20 times a year winds gust to 70 mph, sometimes breaking poles. The heat and cold extremes also took a toll on the luminaires and poles. The city reviewed more than 60 pole designs before deciding on 14-foot fluted Holophane Hamilton poles, as they survived Hurricane Katrina. The city installed ���Teardrop Esplanade��� pedestrian luminaires (Holophane) with 150-watt metal halide lamps. The new poles along the boardwalk are in the same locations as the old poles, which obverted pulling up and replacing expensive Ipe hardwood. The city also installed 22-foot Holophane SiteLink decorative poles with large teardrop Esplanade luminaires, and a modular TracPole system with a North yorkshire base at the end of each street. The poles support adjustable platforms for mounting a flag and flowers. Each SiteLink also has a security camera on the top linked to the Atlantic City Police Department. Illumination from the light fixtures extends 60 feet along the length of the boardwalk and 60 feet onto the beach, providing facial recognition at great distances. The city installed a total of 220 Hamilton and 72 SiteLink poles, mounting two pedestrian teardrop luminaires on each pole. BEFORE AFTER City Hall Square, Fountain, Colorado Above Full-cutoff postop LED series luminaires replaced the high-pressure sodium luminaires at City Hall Square in Fountain, Colorado (pop. 25,846), creating better visability and color contrast. Fountain is located 10 miles south of Colorado Springs. The LEDs are expected to cut the lighting bill in the square by 30 percent, and also reduce maintenance costs. Minnetonka Bridge, Minnetonka, Minn. Right Minnetonka, Minn. (pop. 49,734) hired Energy Management Solutions (EMS) of Chanhassen, Minn. to decrease the city���s overall energy consumption for this posh lakeside community city, eight miles west of Minneapolis. The company identified the high-pressure sodium lighting as a candidate for replacement. The energy saving choice was LED luminaires to relight the stone-faced, 300-foot long Gray���s Bridge, part of Highway 101. Kilmer Electric of Minneapolis installed the lighting fixtures on existing black shepherd���s crook poles mounted on pilasters, part of the bridge���s structural support. One fixture is mounted per pole at approximately 20 feet, with the poles spaced 50 to 75 apart, depending on the pilaster locations. According to Tanuj Gulati, EMS senior energy engineer, the fixtures throw more uniform illumination a greater distance than the high-pressure sodium lamps. ���The luminaires��� white light enhances driver and pedestrian safety, and even though the fixtures are fully shielded, they provide a nice landmark for boaters on the lake after dark,��� Gulati added.
