In some of the electrical supply places they are selling replica antique light bulbs made the same way as the original using a strong filament. They look like the original, and are being made the same way. They are expensive, but look great in an antique fixture or lamp.
There are some replica light bulbs that are using LED technology that look close to the original when mounted inside of the fixture. Nothing looks better than the original. I am using the LED replica ones in our home. This is to have the long life with sort of the original look.
COOOOOL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
FRAN;
You don't seem to care (despite previous complaints of you showing old lightbulbs from ONLY ONE, UNMOVING perspective) that the image of the bulb as seen through the ONE, UNMOVING camera aperature shows no more than if one was looking through a knothole in a board fence.
You, on the other hand, have the option of using TWO eyes, AND ALSO of moving your head to a new viewing perspective, thus affording YOU some depth perception of the filament.
YOU also have the privilege of MOVING THE BULB to any of the INFINITE NUMBER of other viewing perspectives, thus allowing YOUR BRAIN to make a mental image of the shape of the filament.
WHY, OH WHY, don't you ALLOW your viewers to see more than JUST ONE perspective too.
I'll stop ranting now, but I invite YOU, Fran, to view one of your previous videos of antique filaments powered up, and SEE FOR YOURSELF how unhelpful it is to show them from ONLY ONE PERSPECTIVE!!!
Hi Fran, your video inspired me to make my own about some light bulbs in my collection. Sadly i'm not sure if my oldest lightbulb is a carbon filament or else. Feel free to check it out. Dan
I just recently saw on PhotonicInduction a NERNST Lamp. Have you ever worked with one of these before? I'd love to see you do something with one as you tend to go into more detail than PhotonicInduction does 🙂
If you think this bulb is interesting then check out Photonicinductions latest video posted 24th July.
I would include the link but this comment wouldn't appear.
Lovely glow, I think the variac helped stop it going pop, but there again if its not been used why would it go pop if the voltage is the same as its rated for?
But much much nicer than a modern LED bulb. Thank you for sharing that Fran.
Just a suggestion: If you don't lock the exposure on the camera, when you ramp up the voltage you don't get the full effect of the brightness. Because the iris in the lens is compensating for the light and closing down.
Video series idea: Recreating these older bulbs by hand. I'd love to learn to make various bulbs, specifically these tungsten and low pressure sodium. It's on my bucket list of things to do at some point, these bulbs are just as much art as it is technology!
20+ years ago I saw a "human interest" story on the news about a bulb that has been on for around 100 years and never burned out. It was in an old firehouse.
