The Town of Hempstead, N.Y., the largest township in the country, is making the switch to LED technology with the conversion of more than 50,000 high-pressure sodium fixtures to LED street lights from Cree. The installation is already underway with future phases planned to bring LED lighting to the town’s municipal buildings, parks and marinas. The street light project delivers an anticipated two and a half-year payback with nearly $3 million in annual energy savings and US $57 million in total lifetime savings.
