The lamp in the luminaire shown in the previous photo in this album. Image turned around here.

There is, as can be seen, not so much "luxury" left on this badly greened out one.

That's a seriously greened out merc.
I can't help but think that if this wasn't a cheaply made PRC lamp with a quality phosphor then it would be good for a few more thousand hours without that sick green output.

My main area of interest is vintage fluorescent and mercury lamps. Always interested in doing lamp trades - just let me know! Smiley

Like this one. Came any Osram-branded mercs in recent years from anywhere else at all?

Made in PRC. Go figure.

European-made Deluxe HPMV lamps did turn green at end of life too, Dave. This is in fact an issue common to all fluorescent HPMV lamps coated with a blue-absorbing phosphor or filter (Ce:YAG in the case of the present HQL DeLuxe). The reduction in blue light output only exacerbate the green shift of the emitted light color as the fluorescence emission from the red phosphor weakens and the burner wall is increasingly covered with metallic tungsten (i.e., blackening).
