Literally in that linked wiki article:

> "A longer life bulb of a given wattage puts out less light (and proportionally more heat) than a shorter life bulb of the same wattage"

As long as we can recycle (or at least safely get rid of) the burned out ones I'd say its a win from ecology perspective, and at least in some cases also for end users. But this wasnt the main driver of the change, it was the good ol' corporate greed as per the same wiki page.

I believe that the main drive was to stop a race to the bottom where everybody would advertize 1000000 hours lightbulbs but they all sucked and the technology would be considered worthless.

I seriously doubt you can recycle the tungsten as it literally evaporates and oxidize on the lightbulb.
