One of the reason why I will use 3030 sunlike leds (finally) in 8w cheap model was color mixing (another was price and much more power than their old 3030)
I use 4000k, it is better for me than 5000k, but! but 4300-4200 will more better than 4000k. So, now I can mix any colors.
For example 3:1, 2:1, 1:1
For example, 5600-5700 is not white, it is with blue tint (that is I feeling)
Most white for my eyes was when I mixed 5600 and 4000 (SOL) to 5200-5300k. It was most white color what I saw without blue tint (color shade)

And of course, you can mix any colors for duv what you want =)

Hello, peoples of the flat Earth!
Well done! about 6 hours (for this board)
120-240-360-480mA or etc with NSI constant Current Regulators (yes, it is not cheap)
from 18v to 25v
also you can give 12v if instead of 1 LED, you will set a jumper (wire)
also you can use led driver if you will set a jumper (wire) except CCR
12×99×1.6mm m3 holes
also you can cut up to 1.5+mm from the both sides

I took its best result (so 2700K): currently ranked #21 with a BLF Qfactor of 78 and a C- grade. Its clearly better than the previous Trådfri you reviewed earlier, but it is let down by its R9.
Kinda, I "pixelball" those, counting pixels thanks to paint.net ruler
If you have an easy way to give me the exact actual values of your R12 tests, pastebin could do, it sure will polish the table and perfect its targetted "scientifism". And it sure helps !
Aha, you failed to mention that you do not want kerosine light sources, so here is a high CRI entry: an Aladdin no#23 (with Lox-On mantle) on full power:
Wonderful, as I understand, yttirium derived mantles looked rather green. Thorium derived mantle lights improved the color removing some of the green. These lights are , nonetheless, adored by those that live near them—Berlin residents. Berlin still uses 30,000 gas mantle lights in its streets. Here are some sample pictures. The 9-11 mantle lights throw around quite a bit of light, rivaling some electrical lighting systems. The 4 mantle lights look good for residential, you don’t want to light up peoples’ homes like a baseball park.
As I also understand, the Coleman dual mantle lanterns also produce some 850 lumens of warm white light, even outperforming the BLF LT1!
It does look rather yellow indeed, nothing of the rosiness that people here prefer. If this type of lighting ever takes off you can recognise BLF folks by a minus-green chimney
If someone want LED with high cri without violet. For example, I am going to do lamp for nail extsntion
I will get more deteiled result tomorrow. I think it is almost CRI97. It is the same manufacturer what produce SOLs — SmartEcoLightning
Something that's bothering me since the start. I thought that SOL and SAW were both produced by SSC, but manufactured in different countries. But now I'm understanding that:
SAW are made by Seoul SemiConductor / Toshiba (Korea/Japan) : violet crystal tech
SOL are made by SmartEco Lighting (China) : blue & violet crystal tech
