Sometimes I really want to get adjustable LEDs for winter, but it is hard enough to find warm ones with a high enough CRI. I once ordered and returned about 8 different bulbs which had price points from €2 to €100, before going to Ikea and buying bulbs there.

I am going to be redoing the lighting in a house I just bought. I went down the rabbit hole of learning about all the options. It’s hard to find but it is possible to find dimmable, tunable LEDs with a high cri and have matter support so I could use them with Home Assistant. I haven’t actually purchased any though so I can’t report my experience.

Please share your experience when you get to it! I try to avoid iot stuff though and thought of something simpler like dimmable lights that get warmer when dimmed - like the Ikea ones, but with 2700k as the highest point it does not really work.
I thought that maybe the ideal solution would be to wire DC lightning with relays controlling groups of different temperature LEDs. Maybe glueing LED strips to the ceiling and a translucent film under them to diffuse it a bit? I feel like ordering a giant bin of random LEDs should lead to the best possible CRI.
Also each of the 8 bulbs I ordered had Ra>95 written on the box and they just lie because I can instantly tell that the light is wrong. Bad CRI is so prevalent that friends come to my house and think my lights are incandescent.

I did buy a super expensive dimmable tunable led strip from Yuji LEDs. It was expensive even before the tariff situation, so really bad now probably. But the LED was top notch. I followed a guide someone had posted to reddit to make a SAD lamp, and used ESP Home to make it so it made a sunrise effect starting all the way as far yellow as it went and ending at the brightest point. It is just a strip with 2 different temperature LEDs on it and it combines them with directions from ESPHome (oh I had to get a controller for the ESPHome connection. It’s just a “dumb” strip that you have to control the voltage to change).
Since programming it was rough for me, I had some fun experiences where it would just randomly go from super dim to full bright while I was sleeping and hoping for a gentle wake up from a nap. My half asleep brain really thought someone had opened the curtain to the sunny outside. I started thinking of my project as “sunlight in a can”.
Anyways I happily shipped that expensive project off to my brother who suffers from SAD and he never used it even once.
