Voltage- 118vWattage/rating- 32 watts (or 32cp?) Filament- Tungsten, 6-over-7 (thin supports on top, thick ones on bottom) Cap type- E27 "ES" Circa- 1910s Finish- Outside-frosted glass Origin- Germany- Berlin? 3 inches in diameter and 5-1/4 inches from the base to the very end of its long exhaust tip, this wonderfully preserved European Osram lamp is probably originally from Berlin, Germany although I got it from someone in the States. The construction of the base, the most noticeable feature being its thick "bulged" glass insulation, gives it away as European though. It has a tungsten cage-type filament with thin supports at the top of the cane inside and thick ones at the bottom, which can be seen by peering through the short clear neck. This is a sign of a very early drawn-wire tungsten lamp The rating is printed round the top of the base, and states "118v 32K". The voltage is easy to recognise as 118v but the "32K" rating is a bit odd. I originally believed K was just a German symbol for candle power- and was partially right, it infact refers to "Hefner Candles", a German lamp rating different to British/US Candlepower. In the US, lamps were rated in watts long before tungsten ones arrived. In Europe, we did things differently although I don`t know for sure when the switch to watts was made. Updated- July 9th. I originally referred to this lamp as being British, however have recently learned it is probably from Berlin, Germany- and have updated the details presented here accordingly. Thanks to James hooker for his information.    |
