I am new to this light bulb hobby & site; I purch some old lights from an estate sale some Edison /Masda/ Ge. I found out by trying 3 of them in a lamp that they burn out instantly, then tested others with a 9 volt battery & found out most were DC & they worked. My Question is what is the proper DC voltage these old bulbs used, they are sm. wattage with standard base (pat'd 1904) with tips on end .
Also found some sm 10 watt bulbs globe ,(or hot air balloon) shape. marked WABASH, with a circle with A in the middle, these are colored glass not painted , red, dk. amber, & 1 lt. blue glass. I couldn't find any referance to this company name on this site. Thank you. & sorry to be so long winded. Rob Stub.
