Apparently HPS lamp uses xenon and mercury uses argon as starters. Lined up to check the 611nm 616nm lines relative to the europium activated yttrium-venadate DX coatings.

Mercury and metal halide lamps indeed uses argon for starting, except Philips HPI and HPI-T lamps, that uses neon-argon. HPS lamps uses xenon for starting, but the ones for retrofitting MV lamps, uses argon-neon.
There are some manufacturers that applies the Eu:YPV phosphor of the /DX mercury lamp, also to their HPS lamps, but the majority of diffused HPS lamps, simply uses a non fluorescence diffusing coating.
