Hi all,
I visited the Museum of Science and Industry in Chicago yesterday. Lots of cool stuff. One of the strange things was the 100k watt bulb with a 115volt. That's 870 amps!
The filaments were about 3/16" diameter. The bulb is about 24 - 30 inches tall. There was no documentation / description that I could find. I have no idea if it was experimental or for stadium lighting or movie studio lighting.
A similar 75k watt bulb is on display at the Henry Ford Museum in Dearborn, MI. Various other museums have one as GE produced a bunch to commemorate the 75th anniversary of the light bulb. I don't think these were designed for only 115 volts.
No discussion needed, just wanted to share a technical curiosity.
My photo was too dark so I found this one on the webs...
