I am a technologist and a historian. I appreciate the longevity of the incan as a technology but the LED combined with Lithium battery was a game changer for the flashlight business. Also, look at what the LED has done for home lighting. I cant remember the last time I changed a light bulb.

Personally, I would not go back to incan’s but the historian side of me loves to read about them.

Good video.

Good old original incandescent light bulb can have long lasting lifespan especially if it work not at full power. Original bulbs can last longer compared to modern bulbs from 1000h lifespans. Just read that https://spectrum.ieee.org/tech-history/dawn-of-electronics/the-great-lig...
Also today cheap LED bulb for 2-3$ can’t operate at 50000h as advertised. To go to that low price before 3-4 years ago most LED bulbs has used buck switching driver and full metal body. Today most of lights use cheap single chip linear regulator which have low efficiency also they integrate in plastic body little aluminium heatsink which can’t dissipate heat from LEDs. Most of time failures of LED bulb it is from overheating and low quality components.

Run an LED at lower power and you also get lower heat and longer lifespan.
That’s not exclusive to incan, that’s all electronics.

Nice. There is a lightbulb in San Fransisco California that was installed in a fire station in early 1920. It is still working after all these years, but it is not very bright. A kerosene lamp is brighter, but still a testament to the longevity potential of a low power lamp. It also helps that ot hasn’t been turned off or on in a really long time. The on-off cycling hurts incandescent lamps.
