GE, originally founded as the Edison Electric Light Company, was The light bulb pioneer in the late 1800s when lamps were still made with carbon filaments. GE first patented the tungsten filament in 1906 (these clearly have tungsten filaments), though it took a later 1910 tungsten metallurgy invention by Coolidge to make it practical.
Clear Projection Lamp
250W 115V T14
C-13 Fil. Med. Pf.
This Bulb was made for picture projection, 250 watts with a filament zig-zagged across to make a large rectangular light source instead of just a bright line from a single filament.
I believe this bulb dates from the late '30s. It sat for many years in my dad's cupboard, along with his home-made photographic enlarger & other darkroom equipment, sitting idle as he was sidetracked by raising his large family.
It is unused. The filament continuity is good, glass looks good, seal looks good. The base is oxidized. The box & packing is intact, but a little mis-shaped from years of sitting.
