First of all there no metal halide salt in Mercery vapor Lamps.  Second why mecury lamps go EOL turning green and dim. That cause Emission mix and tungsten is deposted On wall of the arc tube. This blocking the light output.

Not all metal halide lamps turns green when they gets old. I've seen ceramic metal halide lamps that turned dim warm white or even dim red. I've even seen halides depleted metal halide lamps, that looked bluish white, despite showing only the mercury lines in the spectrum.
