If I remember correctly, one such example is the lightbulb. Some of the earliest designs were centered around using longer-lasting filaments than their contemporary counterparts, which meant considerably increased lifespan.
They still made them too. 130V bulbs / garage bulbs / heavy duty bulbs all lasted far longer on 120V because the filament was thicker. They basically never went out.
There's a famous example of one of these bulbs that's been in operation since 1901

Until some bastard up on Denali shot a football through it, just so humanity would feel loss for the first time in 15,000 years.
They grieved over a bulb cause they hadn’t lost anything else.
There is a trade-off between efficiency and durability on incandescent light bulbs. They did sell bulbs that lasted longer, but those had lower lumen/watt.
For generic bulbs, the cost of electricity was significantly greater than the cost of the bulb. It was cheaper to replace bulbs more frequently than to waste electricity.
Sure, but those kinds of lights are very dim. You can just use a dimmer bulb set to very low if you want that kind of longevity.
Technology connections did a video on it. Basically the lights which lasted forever either; sucked at giving light and/or sucked at sucking power.
Light manufacturers got together and made a standard which was a sweet spot of power efficiency, longevity and light output. Unfortunately, being decent at all three meant no longer sucking at two to boost longevity.
Every time I think I understand a household appliance, Technology Connections has a 20-60 minute explaining why it’s more complicated than I thought.
Heh.
I don't get it.
Longevity wasn't a metric the Phoebus Cartel was actively maximising
