The Necklace of Lights is a string of more than 4,000 lights encircling the 4.82 kilometers (3.4-mile) Lake Merritt waterfront in Oakland, California. The last major re-lamping of the 90-year-old landmark took place in 2006, when 11-watt incandescent bulbs were replaced with 3-watt cold cathode compact fluorescent bulbs. As the cold cathode bulbs aged, replacements became increasingly expensive and hard to find. The City of Oakland needed a solution that would deliver high-quality illumination, energy savings and longevity. Working with local MaxLite distributor San Leandro Electric Supply, the city recently replaced the 4,500 cold cathode bulbs with MaxLite 2.5-watt LED Marquee Lamps.
