TLDW: The Phoebus Cartel established 1000 hours as a baseline to get maximum efficiency. longer lasting bulbs would require WAY more power per hour to operate while producing less light.
Planned obsolescence is indeed a thing, but using this as an example of it is incorrect and discredits the overall argument. It’s better to focus your attention on right-to-repair laws for your $2000 laptops and $40,000 tractors than on your $2 light bulbs.
#NUANCE NEEDED.
Alec is making a point specifically about the 1000 hour maximum which was for INCANDESCENT lightbulbs. You know, the ones that aren’t used anymore.
However, modern LED lightbulbs are typically over-driven and under-cooled. This drastically shortens their lifespan and worsens efficiency. But this might just be because it’s harder to sell a $20 light that lasts for 20 years than it is to sell a $5 light that lasts for 5-10.
Or maybe it’s because they both claim to last 20 years and we have no way to compare
