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.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.
