@jwcph so, I don't know what wavelength we are missing here but I'm not going to bother arguing anymore.
Frankly, if there's one thing that I think is revisionist? It's the idea that light bulbs could be a durable good in the first place.
Now, we have the technology to make that the case. In fact, we've had the technology for many decades! Fluorescent and high intensity discharge lamps have been around for a very long time. Yet incandescent bulbs stayed the same because they were optimized.
