I have a working, antique bulb from Solar Electric Company, likely manufactured early 1900?s.
It has a mushroom-shaped, frosted bulb, with a manufacture label on the bottom and a decal across the entire top reading ?LITHOLIN?.
The orange glow is the photo shows the bulb lit, using a lamp dimmer.
Can anyone provide any insight into the history of this bulb and its manufacture, or, direct me to some resource that I may reference.
