Osram 150w SON-T Plus

1 x NOS UK-made 150w high pressure sodium lamp.

Always nice to see these UK made NAV-T lamps with the old G.E.C style packaging.

Interesting how the lamp packaging has the old G.E.C codes on it while the lamp has progressed onto the Osram Vialox branding.
The internal construction is is still classic GEC though.
