Sylvania 69/108W SPX Eco Arc HPS Retrofit Lamp Here is a Sylvania SPX Eco Arc high pressure sodium lamp which is designed as a retrofit lamp for either 80W or 125W mercury vapour fittings. It has a specially designed arc tube which operates at a higher voltage than standard HPS lamps and vapourises all the mercury and virtually all of the sodium when running. It has a glowbottle starter so it can operate directly on a mercury ballast without the need for an ignitor. It also has a Philips-PSG-style ignitor inside instead of the usual barium at the cap.

Not seen one of these before for low wattage mercury replacement. GEC used to make a 120W HPS (Solarcolour) lamp with a snap starter, before the 70W SON appeared, but I think it was designed to run on its own gear, although probably would have worked on a 125W MBF/U ballast. Now a rare lamp to find.

Yeah, got one of those, they also made coated versions under the Osram name. They used a dedicated ballast, which are harder to find than the lamps. Must put the pictures up.

Surprised never saw a coated one, only clear elliptical. I had one as a kid but handled it too much and the top arc tube spot weld broke off leaving it flapping about with no connection Sad

Those SPX EcoArc lamps were really nice, with a truly state-of-the-art HPS burner inside. Sylvania did a lot of research work on unsaturated-vapor sodium burner and raising the arc voltage was a really good move to ensure a seamless compatibility with mercury gears.

I've been looking for another of these, as I like to have two of things when possible. Haven't seen one, sadly Sad bulb icon

Those were not really in widespread use as far as I recall.
