World's longest-lasting light bulb, 110+ years!

[JEDI]

It's an incandescent being run at like 12 watts. You could do the same thing with most any incandescent as long as it wasn't garbage. Crank it up to normal voltages and see how long it lasts, then replace it with an LED bulb.

last century: they could have made a 600watt carbon filament lightbulb and run it at 60watts. (much like this higher rated lightbulb running at 4watts.)

would have been decades longiveity vs the 1000hrs for a regular 60watt lightbulb?

The "long life" light bulbs that you can buy are basically that, they're rated for 130 volts or something, so when you run them at 120 they are running below spec.
