That quote is about low voltage technology. Edison’s design changed dramatically over time, his early bulbs used a carbon filament just like the quoted example. Tungsten bulbs invented by Franjo Hanaman in 1904 where a significant improvement on that design and he’s arguably the actual inventor of modern incandescent lightbulbs.

Similarly, the gasses uses inside bulbs and the filament design all changed significantly over time.

PS: Arc lamps like florescent bulbs are “high voltage, low current design” however all early incandescent bulbs where low voltage. Edison improved the design of low voltage bulbs, but he hardly invented the idea.



Um, I said Edison's innovation was a high voltage, low current design. Not the other way around.


I am pointing out high and low is a relative scale. Relative to neon lights or other arc lamps all incandescents are low voltage.


The other incandescent bulbs at the time used low resistance, high current bulbs, which consumed far too much power.


His direct competitor at the time had a patent out 1 year sooner, entered mass production one year later, had as you say lower resistance. (Blanking on the name).

Prior to this various different bulbs where created that had more or less resistance. It was a wild time period prior to centralized power distribution.
