The 325w lamp was actually made to be a retrofit on 400w mercury ballasts. I have one of these, plus a 400w I-line. They use a different arc tube chemistry than standard sodium scandium lamps.

May all the great lighting technologies have their place in history.

That is what I had originally heard too, but I couldn't find the data to support it. Thanks for the info.

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

Maybe I should find one that work with my 400 Watt Mercury Vapor Lamp and Makeshift Fixture

Pretty, please no more Chinese failure.

These lamps are very interesting, the design is in fact almost identical to GE’s first metal halide of 1964. The arc tubes are filled with a tri-band sodium-indium-thallium mix and the outer bulbs are under vacuum. This gives a good quality light of high colour rendering but the initial lumens are low, lifetime is short, and there are big variations in colour from lamp to lamp and during life.. However they are easier to start, hence the use on mercury ballasts.

In the late 60s GE changed all of its metal halide lamps except this I-line to copy the Sylvania design of sodium-scandium fill plus gasfilled outer jacket. That solved nearly all the drawbacks of the tri-band chemistry but raised the starting voltage and precluded their use on mercury ballasts.

Nice!

-Date decoder of most US lamps 1960-present.

-Collects all types of lights.

I'll save any vintage lamp... dead or alive! Smiley

Cool! Those lamps are somewhat hard to find.

How these lamps can be operated on 230V OCV? Have they two starting probes or they have neon-argon penning gas?

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.

I have a coated one some ware in the box of field bulbs which is buried in the maintenance shed. It has the general GE electric arch etch on it.
