#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.

I'd absolutely recommend watching Alec's video, but that's not a half-bad summary of the main point.

Think about it hard enough and it does make sense that for something as cheap and easy to produce as a light bulb, it stands that the consumer and manufacturers alike stand to benefit from a shorter, but more energy/cost efficient implementation, than a longer-lived, but significantly less efficient/more costly version in general use.

Edit - Though it should be pointed out that this is a rare instance of corporate interests lining up with the best interests of the majority of consumers, not something that happens very often, so you could see why people (even myself) would be drawn to believing a more nefarious reason for the 1000 hour lifespan if you didn't know the technical details.

I literally just watched this! Very good video, as is the rest of his content
