I'm appalled by the state of LED lighting.

I would rather change every incandescent in the house for the next 20 years, than figure out all this.

I have an attuned sense for good lighting. I just do. So if I want good LED lighting, that doesn't look flat or cheap, I have to figure out the Color Rendering Index. That's a single number which tells you how good the LED is at showing true color, except, it's a scalar value that describes a 2D vector of possibilities (magnitude x spectrum). So not all CRIs that have the same value are the same quality.

You mean I have to figure out which LED bulb is gonna make red look red?

This is all setting aside color temperature, which at least is pretty straightforward. I've been a 2700K man since day one.

But there's the dimmer situation which is the complete wild west. Not all bulbs work with all dimmers, not all dimmers do a good job for all bulbs, and if you choose wrong you'll either get a dimmer that doesn't dim all the way, or you'll get flickers or random cutouts (think 6 recessed lights of which 2 cut out early as you dim).

Companies publish spreadsheets to tell you which bulbs dim with their dimmers and how well. SPREADSHEETS

And, seemingly, the only dimmer switches that function well are cheap plastic shit. There are no good dimmers that also look or feel high quality.

Line all this up against Prior Era where I would go to Home Depot, pick out any fucking random bulb I wanted, and it would look great, work great, and dim great.

Someone please tell me that the end-to-end carbon cost of making LED bulbs vastly outweighs the energy savings so I can be even more validly self-righteous?

To be honest, I have the inverse preferences, I will work with something janky if I get to mess around inside it, so my recommendations are a bad fit. That said, mixing lights may be a good option, as well as using light strips or EL wire, basically a bunch of LEDs in a plastic sort of wire. They can have a range of different profiles along the strip, so you could have every second LED drop the blue or green a bit to pull the balance towards red, or have a tiny bit of added red alongside the white phosphors. Good luck!
