Where do you find such treasures? Did you work for a lighting company or was collecting for a very long time?

Power provider: Southern California Edison (SCE)

-Date decoder of some US lamps 1960-present.
-Switch and receptacle collector.
-I'll save any vintage lamp! Smiley

No My hobby is to collect mercury rectifier tubes and I don't search lighting lamps.
But sometimes when I see a very unusual lamp I decide to obtain this lamp too.

You certainly do a great job acquiring rare and valuable lamps while not looking specifically for them. Your contribution so far has been really interesting! By the way, this СВД-120 is another nice lamp, do you know what was its application exactly? Was this lamp used specifically for technical purposes (e.g., blueprints, PCB exposure, etc)?

You are right -- as usually )

This lamp is really interesting.
As discharge tube inside this lamp was used another serially produced lamp -- type "SVD-120A". Moreover, some time later the name "SVD-120A" was changed to name "DRK-120", and name "SVD-120" -- to name "DRSh-120". But there are lamps already named DRSh and have significal differences -- also super hight pressure lamp but with another design.

Maybe this lamp was used for blueprinting -- because the "naked" SVD-120A aka DRK-120 is too fragile and dangerous.

That is certainly an unusual wattage for Mercury Vapor bulb

Which ballast did you drive this bulb?

Pretty, please no more Chinese failure.

Was used HPS ballast, lamp current was monitored and its value was in the correct range.

Thanks for the info. Do you know if this particular lamp was first introduced in the 1950s or the 1960s?
