Mercury free HPS lamps, produces a much yellower light color than standard HPS lamps: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-135003
However I see that the starting wire is connected permanently, which means that it draw sodium ions from the arctube when hot, shorting lamp life.

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.
