The various manufacturers actually conspired(spent a lot of money on research and development) to a 1,000 hr operational benchmark. Profits exploded. This is common (engineered predictable fault.)
minus-squareInfrapink@thebrainbin.orglinkfedilinkarrow-up17arrow-down1·3 months agoThe Phoebus Cartel was objectively terrible, but it turns out there are perfectly good engineering reasons to limit them to 1000 hours. It has to do with the chemistry of tungsten. Those bulbs that last forever give off exceedingly little light, and the 1000 hour rule is from a standard that predates the cartel.
