In the real world people don't care if their CFLs burn out and get replaced with LEDs because CFLs are comparatively terrible and you can get a higher quality LED bulb for about $5.
True, I was just trying to explain this to my partner who didn’t want to throw out still functional CFLs. In this case the value of the estimated remaining life of the CFL + cost of new LED is less than the expected power savings of the LED.
In the real world people care about both actually.
I submit that there are vanishingly small number of individuals who would spend more on bulbs than what those bulbs would save in electric costs over their lifetime.
