So what is different about this bulb versus a regular filament one I can get at wal-mart? And more importantly... where can I buy one at?

- jedimastert 7y agoFairly little, actually. The main difference you'd see is: 1) It's a 30-watt bulb, so I'd be a lot darker than you'd be used to/would be usable 2) It's gotten even darker, so it would be almost completely useless by now. 3) Because of the lower wattage, it's basically been used more gently than any bulb you'd use now-a-days Basically, you'd probably replace it about as soon as the current ones anyways.
- Nextgrid 7y agoRegarding point 2, anyone knows why it became darker? Furthermore in the Wikipedia page they mention that when the lamp lost power for some time, it became much brighter a short time after it was powered up before dimming again. Can anyone explain that? I'd expect it to be the opposite, where the hotter the filament gets the more light it produces.
- greenyoda 7y agoThe article says it's a carbon filament bulb. Modern incandescent bulbs use a tungsten filament. Carbon filament bulbs are still sold for decorative lighting: https://www.amazon.com/carbon-filament-bulb/s?k=carbon+filament+bulb https://www.amazon.com/carbon-filament-bulb/s?k=carbon+filam... Kind of related: an interesting video on how tungsten filaments are made: https://www.youtube.com/watch?v=DIGqBb3iZPo https://www.youtube.com/watch?v=DIGqBb3iZPo
- ars 7y agoThe bulb is basically a space heater, not a light. It glows red and doesn't give off much light. Like the coils in your toaster basically. And that's also why it's lasting so long - low temperature equals long life.
