Sunlike 15-16D
Woah, that absolutely blows away my Hue Ambient, which are about Ra 83. Thanks for the tip, just ordered 8 to try. Love the Duv at 3000k, as thatās my go-to interior light.
I see that Yuji released a CRI95 zoomie bulb:

I wonder if thereās a chance of a res-mod or another power upgradeā¦.
Sunlike is good and better CCT but longer wait and higher price.
They said they ātested these 12,000 hoursā
Sunlike, have you considered Nichia V4 COBs?
According to my rough calculations, when underdriven they should deliver close to 140 lm/W at 85Ā°C with CRI 9580.
If it has a blue bump I can predict the future: no
Heās already said that to other suggestions
I think in about two weeks I will be offering LED sources (E27,E14,GU10 5-9W) based on Bridgelux THRIVE.
The light they emit seems very pleasant 
Below is a basic comparison of the spectrum emission compared to Citizen 97 CRI and Sunlike LEDs:
Nice upgrade Bocian :+1:
BTW, do you intend to introduce some higher power dimmable bulbs?
I also think so but I thought it would be worth asking. I would surely find some uses for themā¦
TIL Citizenās primary business is LEDs, very interesting!
Suppose their watch brand is more of a holding of the larger company like how āSeiko Epsonā owns the Seiko watch brand as a tiny sliver of everything else.
BTW, I notice that the Citizen chart mentions CRI97min. But I only see CRI97typ on their website. What do I miss?
Interesting! I've been trying to keep an eye out for (reasonably priced) home lighting products made with their new Thrive lineup. My ultimate would be a zigbee-controlled CCT/dimming option. It looks like their Vesta series does 2700K-6500K, though frankly I never use above 5000K.
Where should I keep an eye out for more info? @bocian
There is a LED bulb producer from Bulgaria V-TAC claiming CRI > 95. Do you have any tests on that?
Given the 10-17W power rating, the bulbs looks like they have no heat sinking to handle the heat. These will likely die prematurely.
It seems this is the reason they are so cheap - here in Bulgaria, they are selling them for around 2.5 EUR.
I am actually searching for a high CRI Ceiling Light with a form factor fact like that one:
I can see one in amazon Onforu LED IP65 Ceiling Light, which claims CRI> 90.

Could you recommend any?
I can see one here SunLike48-54armD ŃŠ²ŠµŃŠ¾Š“ŠøŠ¾Š“Š½Š°Ń Š»Š°Š¼ŠæŠ°, but it is not in oval form.
They are in PL as well. I considered them until I saw some CRI97 lamp (or bulb?) that they claimed to make over 150 lm/W at very low price.
I donāt trust their ratings and I wonāt buy them.
Iām shopping for similar lightsā¦and I chose to go with simple lights that are based on E27 bulbs, either for all or for most rooms, not sure yet.
The reason is that:
- The part that fails from time to time is inexpensive and easy to replace
- Thereās a lot of choice of CRI97+ bulbs as well as bulb-based fixtures, but nearly all fixtures with LEDs have just CRI80
- I consider some of the bulbs that over-saturate colours for the dining room, good luck finding one with LEDs already installed
Though I like how the diffuser is uniformly lit in LED-based fixtures. And for that reason I consider buying a fixture and filling with LED strips. Though itās more work, not so easy to replace (still quite OK) and actually there are fewer good strips than good bulbs.
I am thinking to implement it the same way as there are some options on E27. The downside could be that the light is not evenly distributed as with the integrated LED. I am also not sure how the diffuser will affect the CRI.

Maybe I will conclude on buying some E27 Sunlikes in combination with any of the options above.
For the rest of the installation I plan to buy some GU10 Philips ExpertColor (or Sunlikes on GU10 adapter, but donāt like the adapter idea). Another option is GX53 Sunlike - SunLike5-8 GX53 ŃŠ²ŠµŃŠ¾Š“ŠøŠ¾Š“Š½Š°Ń Š»Š°Š¼ŠæŠ°.
If you have the skills to do it then it is ok, and you have to be careful not to implement a āzebraā light effect with the strips. One of the good led strips are produced by Auxmer - https://www.aliexpress.com/store/3754011?spm=2114.12010612.pcShopHead_10395427.0. There are also tests in the forum here - High-CRI LED light strips - Google Sheets.
I chose to go with Lidlās Livarnolux for the bulk of my bulb needs. But I have some uses for better bulbs as well, these will be filled by either Sunlike or Bocian.
Some interesting findings from Delta Light, Belgium. The cons is that they are very expensive.
Soli 52 claiming CRI > 98
CONFORM P28 PDS DOWN-UP 954067 B-B - Delta Light claiming CRI > 95
https://www.deltalight.com/en/products/detail/imax-ii-round-adjustable-mp-93039-24211-9330 claiming CRI > 90
Considering that there are good 5+ cm of height to the diffuser, thereās little risk of zebra effect.
