I think this must be one of the oldest 50W mercury lamps I have seen! I assume this is an orthophosphate coating?

1962! Amazing!

Andy, thats a perfect question to James. I have no informations about the phosphor in this time. Orthophosphate will be used in this time.

Nice, that’s maybe the oldest 50 we’ve got on here!

Thanks for all comments,

here is the second picture. The green ring on the socket is good visible. That was typical in this time.



Regards

Olav
