Impressive! Is this a lighthouse lamp?
Thanks for posting!

Interested mainly in discharge lighting (mercury, sodium, neon) and also old and unusual incandescents.

I don't know. Could also be a normal spotlight lamp.

Most impressive, I think it is earlier than you suspect, due to the presence of the exhaust tip on the bulb.
It is probably a projection lamp, because lighthouse lamps normally have filaments that are more rotationally symmetrical.
Interestingly the leadwires are not made from wire, but flat metat strips. That was done by many manufacturers around the world from about 1915 to the early 1920s, but I don't know why.

https://www.youtube.com/watch?v=oz8xhbCAJJM yours has a tip, so probably manufactured before 1928

You guys were right, this is actually a projection lamp made in the 1910s. I got an original brochure from 1916 now.
