• Abstract:
  Solid state lighting technology is advancing rapidly to a point where light emitting diode (LED) lighting ; systems can be viable replacements for existing lighting systems using high pressure sodium (HPS). The ; present report summarizes analyses conducted to document existing lighting conditions along a parkway ; (Southern State Parkway, Long Island) and an arterial roadway (Central Avenue, Albany County). Several ; LED alternative lighting systems were compared using photometric analyses to identify ones that meet light ; level criteria for each roadway type; several options were available that resulted in energy savings compared to ; the existing HPS lighting systems. Energy economic analyses confirmed that the initial investment could be ; paid back in terms of reduced operating costs, and that energy savings were larger for LED systems when ; compared to HPS systems that produced similar levels to those from the LED alternatives. Further energy cost ; savings would be expected with the use of adaptive lighting controls specified to take advantage of temporal ; nighttime traffic patterns on the roadways investigated. The report concludes with considerations for ; incorporating LED performance characteristics, such as ensuring they do not produce interference with radio ; equipment, into specifications for LED retrofit alternatives.
