Low Pressure Sodium - Single Ended (SOX) Lamps
Improvements to the Integrated sodium lamp came in 1964, when the exteriors of the outer bulbs were covered in a thin oxide film to further improve the thermal insulation of these lamps - the fabulous SOX lamp was born.
I currently have examples of lamps made by the following manufacturers:
| GEC | GE | OSRAM | Philips | Radium | Thorn | Wotan |
