Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

Added to the table!

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.

Do you just eyeball the R12 values? For the Ikea it was easy, but I could post the test results on pastebin in the future if that helps.

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 !

Yeah, all the CRI R# values are listed there under #CRI Data. R12 on line 66.

Look what I found guys and gals, for about 15$US:

CRI95+ rated too.

Also something else that looks superb for Canadians:

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:

CCT=2720K, duv=+0.0027, CRI=97.9, R9=94, R12=94, Rf=96.8, Rg=97.6

Curious, +0.0027 Duv. Would you call that green yellow?

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 :smiley:

This might be of interest to some. Not the first time the 500W Yuji is tested though.

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

Ahah! Well done, kinda got me there. Well, well, well what mention should I add to disqualify those solutions?

  • I do not want to become radioactive?
  • I want lights to be able to run from sustainable energy sources?
  • "No Amish tech"?

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

Is it right?

Yes. SOL is from China. It is not TRI-R technologies

And is there any relation between SSC and Smart Eco Lighting companies ?

I do not know

Just found an interesting high-level article, speaking about SOL and SAW differences, and doing that using some of Adam's product offering.

PS : by the way Adam, are you Ukrainian or Belarusian ?

Bought a Lidl Livarno Lux LED E27 smart bulb. Strong do not buy from me.

-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


This SOL/SAW thing is confusing. Tell me if this is right or not:

SAW = Original by “Seoul Semiconductor” (Sunlike product line) in Korea
SOL = Better/cheaper by “Smart Eco Lightning” in China
