Alpina Branded Swiss GLS

Alpina Branded Swiss GLS

This Swiss plant operated between 1904 and 1981 at 74-76 Hintere Bahnhoffstrasse in the Swiss town of Aarau.

There is no discernible date code in this example but it might be molded into the press, but that is difficult to see. Judging by the packet artwork I'd say late '50's eerly '60's.

The filament is a two support coiled-coil part wreath (2HE) and very modern for a lamp this age. This manufacturer must have been quite early to adopt this very common design which was to proliferate so greatly later outside the North American Realm.

Note the marking of "930 lm" and the "William Tell Crossbow" symbol on both the etch and packet. Efficacy comes out a 12.4 limens per watt, which is quite typical for high voltage realm lamps.

Nice lamp!

Good quality things are awesome. Cheaply made things are not.

Collector of lights and anything else that interests me as long as I have space for that particular thing!
