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.
