Oh that’s a fun one. Original incandescents lasted a very long time. Too long (over 10,000 hrs, and there are many examples of ones that have been lit for decades!). The various manufacturers actually conspired(spent a lot of money on research and development) to a 1,000 hr operational benchmark. Profits exploded.
