"rail10"
Which of the metro rail stations uses sodium ,metal halide and mercury lighting also which ones uses warm white fluorescents as opposed to the general cool white and daylight fluorescents and finally whichpartof the stations uses incandescent lighting?
Compiling such a list would require surveying every station in the system. Mercury vapor lamps were the primary type installed on top of pylons up to the mid 1990s. Cool white fluorescent were and are the primary type of tube used, however warm white fluorescent tubes have been used as replacement over the years. Incandescent lights were phased out in the 1990s and replace by compact fluorescents.
