Here I show a hand made Shelby carbon filament incandescent light bulb from the turn of the 20th Century. My bulb is a sister to the famous Centennial Bulb, and I take great care in bringing it back to life for you in 2020. Enjoy!

Thank you so much for sharing my kids loved this videos!
Thanks Fran! So interesting 🤔
Nothing but the best.
These bulbs really are something special, they are so rare, I actually have a carbon light bulb. I think mine is very early 20th century. Unfortunately, the seal on it is broken so no powering it up unfortunately, but a cool specimen nonetheless. Also, you made me VERY nervous vibrating the filament that much. They are nothing more than very thin strands of charcoal and will literally disintegrate if you so much as sneeze at them so that made me very nervous. Also just one question, how did you get your hands on any carbon filament light bulb at all let alone a legendary shelby bulb?
Wow, so awesome!!
They weren't making much money back in the day because they made the light bulb so good. So this is why we are stuck with light bulbs that blow constantly
Looks like the idea light bulb💡 I imagine popping up over your head watching your videos😉
I've loved watching your channel since 2014 Fran!! 😀 Love the new vid about disposable consumption
It is a work of Art.
It reminds me of a story my grandfather told me when I was about 11 or 12;
He was in Montreal, during the McGill university riots.
He was standing beside a Surete Du Quebec officer, watching the fires and students smashing a large computer.
A vacuum tube, flew or rolled up to my grandfather's feet, and he bent over, picked it up, and asked the cop if he could have it as a souvenir.
"You can `ave, is garbage now"
He labelled it and kept in a pill bottle.
I inherited it after he died.
He also while in Quebec, visited one of the Mines there, and told me it was opened in
1800 something, and that "most" of the original (Carbon Filament) bulbs, were still lit, working, and never switched off.
"They've been lit for (nearly or definitely) 100 years".
I have one very similar to what was in the Mine. It was never used, but unfortunately, the tip was broken, so it's just a memento.
I have a similar bulb which has a lever on the side connected with cotton string. Sort of a Bright Dim Switch.
There are 2 filaments, each with 2 turns. The dim one has loops about 3/8" dia and the Bright has loops about the diameter of a nickle. It still works. I have it inside a clear glass lens Lantern after removing the wick.
My cousin’s home built in 1820 was electrified in early 1900’s had Edison Bulbs on front porch from around 1910 that were still working in the 1990’s 💡BTW The old pre depression and WWII line voltage was 110. Post REA (1930’s Rural Electrification Act) it’s 120 volts as it is today. In Florida and NJ the line voltage per the Public Service Commission and BPU in NJ is 120 volts +/- 5%.
Why do you square the Watts and then you devide it again? Why not R=U÷I ? 🤪
