The National Electrical Manufacturers Association (NEMA) has published LSD 54, "The Strengths and Potentials of Metal Halide Lighting Systems". Developed by the NEMA Lamp Section, this paper reviews the beneficial characteristics of metal halide high-intensity discharge (HID) lighting, including energy efficient, outdoor, and other lighting applications. The paper argues “for the inclusion
of HID lamps in Energy Star requirements and for allocations of federal
funding to help propel further research and development”. LSD 54 lists
other benefits of metal-halide lighting, such as long lifetime,
high-maintained light levels, and a broad ambient operating temperature
range. This
publication joins about 40 other white
paper reviews in the NEMA LSD series, which cover a variety of lighting
topics.
