Radium 500W Incandescent « on: December 24, 2022, 08:02:33 AM » Author: Mschulz90
Merry Christmas
Since a few days i have a Radium 500W incandescent in my colletion. This bulb was produced in Great Britain. In the list of the factory/date code of Radium is no factory in Great Britain. I think it is maybe a labled Osram/GEC from the Wembley-plant, because Radium was a part of Osram. Perhaps somebody know where this beautiful bulb is produced and the age?  :)
