This paper models the case of a new construction 277 V commercial lighting system, one of the many possible applications of a DC distribution system, using fluorescent and LED fixtures in a conventional AC circuit and in a DC lighting circuit. The levelized cost of lighting for the AC fluorescent, DC fluorescent, AC LED, and DC LED cases are calculated for projected LED and solar PV performance parameters,...
Since the energy crunch, many new energy-saving fluorescent lamps, ballasts, and luminaires have been developed. Various new controls, system components, and technologies have become available. New lighting concepts are being employed for recehktly developed open plan environments. However, these components, devices, and their combinations tend to confuse the end users for either new or retrofit applications...
