On a long enough timeline, everything is disposable. And what is "disposal", really? How many LED bulbs are actually getting properly recycled, and isn't it true that the materials in incandescent bulbs are less harmful, relatively speaking, than those in LEDs?
I don't like LED bulbs, but I think they clearly win the disposal/economical argument against incandescent in every way. Unfortunately they blink and have poor color reproduction in many versions.
Don't the costs & emissions related to manufacturing and transporting all of those incandescent bulbs.
As much as I like the old bulbs, they're unlikely to "win" in this question unless you are wanting to ignore the major lifespan difference.
As someone that has never owned a car, is vegetarian, and walks/subways everywhere, I kinda feel like what's the big deal if I use a few incandescent bulbs every year in my small NYC apartment?
Incandescents can be bad in lots of categories but if they make you happy, that's a huge plus. Some categories are much more important than others.
I'm lazy and prefer not to change bulbs multiple times a year... but the warm light is lovely when I do use a classic bulb. I live in a warm environment and hate the heat they add, but in your climate perhaps it is nice much of the year.
However, if you're like my parents, they buy lots of very cheap LED bulbs which fail quickly and flicker a lot, because since they fail so often, nice ones are too expensive.
I buy bulbs that cost a bit more up front but have less flicker (undetectable to me when waving a hand under them), higher CRI, and last longer.
However, I think I'm probably out of luck -- LEDs are cheaper and they likely don't break as much in shipping. So even if I personally find LEDs to be worse than incandescents -- they don't render reds properly, so even something simple like skin tones don't have the depth they once did, plus they give me migraines -- I likely won't be finding them on shelves anywhere near me ever again.
