SON and CPO WRTL Arcs (including cycling SON example)

[@thelightingenthusiast]

Nice video! Looks like these Arcs have escaped replacement as the IOW haven’t adopted them yet.

@thelightingenthusiast correct. The majority were replaced in 2023, but some weren't.

I have never really seen CPO and they are extremely rare and very expensive lamps!

@@HIDSON-TPIA I don't think they were very common in Greece. True, they are very expensive and also, all but the 140w version have been discontinued now.
