But also in the same wiki page:

"As regards life standards, before the Phoebus Agreement and to this day the general service filament lamp was and is designed to have, on average, a minimum life of 1,000 hours. It has often been alleged—though not in evidence to us—that the Phoebus organisation artificially made the life of a lamp short with the object of increasing the number of lamps sold. As we have explained in Chapter 9, there can be no absolutely right life for the many varying circumstances to be found among the consumers in any given country, so that any standard life must always represent a compromise between conflicting factors. B.S.I, has always adopted a single life standard for general service filament lamps, and the representatives of both B.S.I, and B.E.A., as well as most lamp manufacturers, have told us in evidence that they regard 1,000 hours as the best compromise possible at the present time, nor has any evidence been offered to us to the contrary. Accordingly we must dismiss as misconceived the allegation referred to above."

The statement by UK Monopoly and Restrictive Practices Commission seems to be inaccurate as the objective was an average lifespan of 1,000 hours, not "on average a minimum life of 1,000 hours" as bulbs that exceeded 1,000 hours were fined, as well as those lasting less.[1] That bulbs lasting longer than 1,000 hours were fined, regardless of their wattage used to lumens produced seems explainable only by a desire to restrict lifespans, and contrary to efficiency or minimum lifespans being the goal.

From [1], quoting Anton Phillips discussing members building higher voltage and longer lived bulbs,

“This, you will agree with me, is a very dangerous practice and is having a most detrimental influence on the total turnover of the Phoebus Parties…. After the very strenuous efforts we made to emerge from a period of long life lamps, it is of the greatest importance that we do not sink back into the same mire by paying no attention to voltages and supplying lamps that will have a very prolonged life.”

This is also what Alex explains in the Technology Connection video, and a lot more, with actual examples using actual lightbulbs and some surface explanations of the physics.

I believe his name is Alec btw :)
