Save the incandescent bulbs for winter time use, to save wear and tear on your furnace and get maximum life out of your bulbs.
One key fact about LEDs not mentioned so far : they aren’t all equal. The better ones have color rendering indices over 90 and come at a modest price premium. (3-4 bucks a bulb)
Also, totally enclosed fixtures will lead to premature failure of the bulbs. It makes sense to just swap to LEDs with high cri for all the fixtures you actually use at a minimum.
Also, some brands of cheap led bulb failure prematurely far more often than others. Check Amazon. The Phillips ones I have had excellent luck with.
Oh, another key thing : don’t install CFLs in any fixtures a person can normally bump into. (No lamps). High up on the ceiling in enclosed fixtures is ok. That’s to avoid inhaling Mercury contaminated fragments from breaking one.
LED bulbs continue to improve. I’m moving to them as other lights fail, and the newer ones are definitely better than the older ones.
I care a lot about brightness, color temp, and CRI. If you don’t, ymmv. But I still have some expensive high wattage halogens because I just haven’t been able to find an LED that will replace them adequately. I may end up replacing some sconces with long LED strips hidden in custom-built molding-based fixtures. That won’t be cheap.
I dunno, when I buy bulbs, I get the cheapest ones, without regard for effective temperature or color index or whatever. And the first one I swapped in, for a week afterwards, I kept on going around the apartment looking for what other light I forgot to turn off, because a single LED bulb was filling the room with so much light.
It’s not the amount of light, it’s that if you have too poor a CRI, the colors won’t quite be right. Like the difference between the lighting in a good starbucks versus the harsh industrial lighting in a cubical farm. Also the very cheapest bulbs may have annoyingly high failure rates.
The Phillips ones I have seen on sale for as low as $1.25 a bulb, and they are reliable, and their CRI is adequate for everyday use.
I can sort my blue sucks from my black socks under some lights in the house, and not others. That’s what CRI means. Some rooms are warm and comforting, and others are bright and cheery. That’s what color means.
I’d say swap them all but more because I loathe the light out of CFLs and the savings off the incandescents is obvious.
In my 125yo house, I’ve gotten rid of all but a few IC bulbs. Most of my house has been changed over to LEDs. They seem to handle ceiling fans and motion switches better than the CFs. Also LEDs bring much more light to areas that were dim but I didn’t want to upgrade the fixture. Replaced the ICs as they burned out with CFs a decade or more ago. CFs don’t work in the unheated outbuildings during the winter. That is where my remaining ICs are headed. Most of my remaining CFs are used in fixtures that have some type of shade so that they are not really viewable. Or in places that I want a slow warm up like in hallways were I don’t want bright light immediately at 3am.
