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
-Warm white with a bad yellow tint (2700K, duv +0.0048)
-CRI Ra 83, R9 15, R12 71
-TM-30-18 Rf 88, Rg 94
-RGB modes emit an audible whine
-RGB modes have a very low output, no chance to make a mood lighting unless you buy 10 of these
-PWM is not visible on any mode
-Remote and smartphone bluetooth app work fine, but the colors on the remote don’t all really reflect what the output will be
-About 10x range in the dimming with fine steps
-Power draw 1.2-8.3W on white with a power factor of 0.48-0.59
-Power draw 0.9W on RGB with a power factor of 0.40-0.45
-Standby power is 0.5 watts
