I hate when people refer to the lightbulb conspiracy. Because there’s two sides to the story. The other side is, that tungsten filament lightbulbs last longer at the expense of energy efficiency and brightness, so companies that boasted longer life bulbs did it by cheating elsewhere – and since it’s very difficult for the customers to measure light intensity by eyeballing, thanks to having an iris that adjusts to light and a color vision that auto-corrects white balance, it was a race to the bottom with dimmer less efficient bulbs. What they did by standardizing the operating hours of a bulb to 1000 hours was also standardizing their brightness and energy efficiency, and the lifetime of the tungsten filament at a known input power was actually the easiest most straightforward way of doing the quality control for thousands and thousands of lightbulbs without having expensiv...
