Osram "Relax" unusual 60w GLS lamp

After many years of searching, I have finally managed to find one of these 60w "Relax" lamps to add to my collection. In the early 2000s, Osram sold a range of these lamps in two colours/tones - the "Relax", seen here, and the "Active" with a kind of daylight-blue hue. The latter seem to be much easier to find, I've got at least 3 or 4 in my collection accumulated over the years! These have a fairly similar shape to the old 1970s Mazda "Purlux" / Endura "Fiesta" lamps sold here in the UK.
