staticx57 - so there are other nichia 219b that are not R9080 spec?

Ledpowerforum - yes i know shopee is active in asia like lazada. I thought you are from america thats why i asked.

jon - when you explained from the previous page about how yuji changes everything i got interested with this light. In the C01 vs e01 thread i do have an understanding that yuji is good led but when you say its better than nichia 219b that made me understand this a little bit.

bil - i dont no how to read those charts yet. What do you mean "world of difference between them and the 70-80 CRI emitters one finds in most of the other lights out there. "

By the way how can i know what kind of led in my smartphone xiaomi A1 model. I really like color of this led looks very warming. Is this yujis or nichia 219b. Its not your typical white light.

If you look at the data sheets for most of the common LEDs used in our lights, they are usually somewhere between 70 and 80 CRI. Most Nichia 219C emitters are around 90+, although some are only 80. The Yugi LEDs used in the C01s are 94/96. Look at the example on the page at this URL:

The point I was trying to make was that the Yugi LEDs are not a whole lot more accurate than most 219B LEDS, but they are all a lot better in color rendition than the ones that are 80 or lower.

Correct. The 219B can come with
R0000-Nichia does not guarantee CRI
R8000-minimum 80 CRI with no R9 guarantee
R9050-Minimum 90 CRI with R9 of 50 or better
R9080-Minimum 90 CRI with R9 of 80 or better

Most of your average "high cri" 219B lights utilize the R9050 spec LEDs. Usually if a light is using R9080 spec Nichia it is usually advertised as such. Also worth noting that there is no 219B at R9080 in the 5600k range so there is nothing to directly compare. In general though the R9080 Nichias match what the Yuji does just at different color temps
 
I think part of the attraction is the price for most folks. With fees and shipping you would cut some of the excitement.
I got frustrated with the hoop-jumping for the discount so gave up. They went out of stock while I was waiting for the adjustment. Besides, I can now get both 3200K and 5600K in the Sapphire.
 
Snagged up the last blue 5600K.

Little tip, one gets a slightly lower price on Ali’s app. There’s also a 3 dollar off coupon offer for new customers……….
 
That's funny, everyone said they wanted the red with 3200 and the blue with 5600, and now all that's left is red with 5600 and blue with 3200! Oops. I'm fine with black.
 
The supply of the colored ones must be getting real short. I put two in my cart yesterday at $7.99 each. Today I decided to go ahead and order them and the price jumped to $8.88. Looks like this batch will be gone soon.

As an example I looked up the data sheet for the Cree XHL-HI used in the Lumintop GT Mini. Here are the CRI numbers:

• Typical CRI for Cool White (5000 K – 8300 K CCT) is 65.
• Typical CRI for Neutral White (3700 K – 5000 K CCT) is 75.
• Typical CRI for Warm White (2600 K – 3700 K CCT) is 80.
• Minimum CRI for 80-CRI White is 80.

• Minimum CRI for 85-CRI White is 85. • Minimum CRI for 90-CRI White is 90

The other information I got from the data sheet is that the higher up one goes on the CRI, the lower the output. That is to be expected due to the extra phosphors needed to obtain the better CRI.

Since I ordered the Neutral White, the CRI I can expect is 75. That's a long ways from 94+. It's not a problem for me with this light since I am looking at distance viewing and color rendition is not a high priority at long range.

+1 I agree. I was going to order a red in 3200K and blue in 5600K myself, but since they're out of them I'm just going to forget it. Still waiting on the black ones I ordered in early December.

Sorry, walked right into that one, I edited out the offer.

yes, the 90 portion is an average of the first 8 bars, and is shown as the white bar in the chart, the 80 portion refers to the Red Bar

here is a post with more details about differences in CRI, with more charts, that will hopefully add to your understanding, without being too technical

I just spent $12 buying lithium primaries for my $8 flashlight. This must be CPF. :banghead:

(Yes, I have eneloops. Just like back up options.)
 
LOL, congrats on your batteries

did you get the tritiums and magnets and UV cure glue, and a UV light too?:-)
 
I've got one of each tint ordered.

AliExpress is hands down the worst and sketchiest website I've ever ordered from; I hope Sofirn gets a better dealer figured out soon.
 
I also dont trust unfamiliar sites, but, Ive had no problem with Ali

Ive seen sketchier listings on Amazon
