Lots of comments here about blue-less lighting at night, so I thought I'd share my experiences in trying to warm-ify our household lighting. I'm in no way an expert; just sharing some experience.
It all started when we moved in to our current place. The previous tenants had left a bunch of old incandescent bulbs. I guess I had forgotten in the past two decades just how warm colored those lights are. It is a really comforting color temperature and great for getting sleepy before bedtime. Of course when I went to replace them with LEDs the contrast was obvious.
Now enlightened (heh) to the differences I went on a quest for warm colored LEDs. Turns out, that's really difficult. First I bought just any old light with the word "warm". But most LEDs you find are actually "warm white" or "soft white". Basically 2700K and up. Whereas old school incan. is ~2400K. The difference is huge and I was very disappointed.
So I began to filter my searches looking for things in the 2400K range. The local lighting store had _nothing_ (a store completely dedicated to selling lights). Amazon had a few options, but not many. Once you filter by low temperature and dimmable you begin to scrape the bottom of the barrel. Most were off-brand, which I try to avoid since poor quality LEDs will fail early when their cheap power supplies burn out.
I went through a few rounds of orders but finally settled on a set of Philips dimmable A15 lights "with warm glow effect". They are small enough to fit in all fixtures I've run into for those kinds of bulbs. But the best feature is that they change temperature as you dim them. So you have the option of a cooler "soft white" (2700K) at full brightness, or all the way down to 2200K when dimmed! To a non-expert in lighting they subjectively looked the best and gave us the same warm, comforting glow we were looking for at night.
So my advice, if you're looking to upgrade your house to warm bulbs, make sure to look for something 2400K or less.
Others have mentioned checking CRI, and that's important. I don't know the CRI on the bulbs I got. Again, they subjectively looked the best. But there aren't a lot of options in the truly warm color range so it's a feature I had to not care much about.
I also found some really great vintage filament style LED bulbs for a project (vintage style outdoor string lights with corded wiring; built from scratch). They're from a company I found on Amazon called Cmyk. Off brand, but they're the best option I found in that category and their packaging was actually really professional. They are labelled as 2200K, but they look even warmer than that. When dimmed about half way you get just the right amount of glow that you can see the faux-filaments. Super happy with those.
Beyond that you can also just get color-changing bulbs like Philips Hue. Since all this went down I've been slowly upgrading to those instead. That gives you the option to choose really any temperature you want at any point. I'm not sure how the "quality" of light from that setup compares to a real warm LED lightbulb. Obviously you're getting a "warm" color by mixing red and green LEDs so it isn't a true color temperature. But on the other hand you're definitely not getting blue light, which is the important thing. Either way, subjectively they look great and I wouldn't be able to tell the difference. (Usual caveats about buying into a somewhat closed system applies; Philips Hues are sort of the best worst option today.)
