Isn't there a 96 CRI XHP70 available in 5000K? Expensive and high voltage... but if you want 5000K high CRI it might be the best available.

thanks but not really made for 18650 lights right such as alpha lights?.
XHP70 really works best on 2 xx650 cells. It is certainly possible, I do have a single 26650 MT-G2 light and that uses the same voltage as XHP70. You could also try 2x18350 for the required 6V over the use of a boost driver.

Hi, I got this back from Ted Bai at yuji,and I'm not sure if these can fit an 18650 ;

Hi Darryl,


I am not sure about will our LED be able to fit the 18650 battery or not ...
We have two sizes of "small "LEDs , they are : 2835(2.8 mm X3.5mm) SMD LED and 5730(5.7mm X 3.0mm) SMD LED.
Please find enclosed datasheet for both of them .
I am not sure the luminous flux of LED light can used for flashlight.

Yes, they have a couple of those smallish ones that are 3-4vf typical, and put out around 20-60 lumens each. They also have one that is13.5mm (half an inch) and around 14-16vf that puts out around 1000 lumens. An emitter of that size could only be used on a soda-can style flashlight sporting multiple 18650s and a mule head.

Either way you're talking about very much custom jobs.

neutral, did you ever find what you were looking for in regards to the highest CRI led that can be used in a flashlight? im looking to get the highest CRI possible for my grilling flashlight.

Zebralight SC600Fd Mk III Plus, 93-95 typical CRI & 5000K CCT. Or flashlight with Nichia 219B with 4000K CCT if you prefer a warmer touch.

If you are ok with even warmer tint, why not try incan lights?

good point, i have several surefire incans... idunno, guess its more of a novelty to have a hihg CRI led.

I realize this thread is 3 years old but it's the most helpful one I've found looking for a pocket carry 1x18650 (or a pocketable 1x 21700 if such a unicorn exists). Based on my very limited collection/experience I think a 90+CRI, 5000ish CCT would be my Goldilocks light. Thanks to this thread I've got the Jaxman E2 and the ZL SC600Fd MK IV on my list. Hopefully there are more choices out there now??

Take a look at optisolis range. This is the best thing at the moment. You can get some from Clemence at virence.com, raw or reflowed on dedicated boards ready for installation

There are 5000k and 6500k flavors. You may believe or not, but the quality of light is so high that I dont hesitate to use the 6500 version at night. Before that I would never get anything cooler than 3500k

Yes, the Optisolis series produce some of the very best "artificial" light I have seen.

There are a few potential issues, however.

First is that I am not aware of any mass produced flashlights ( yet? ) using these emitters direct from the factory. So modding will be necessary, one way or another.

Second is that these emitters are rather limited in output, at least compared to most other modern emitters. They produce plenty of light for simple EDC purposes, but these days many seem disappointed if a tiny pocket flashlight doesn't put out 1000+ lumens.

Third is that they have an oddly asymmetrical shape, which can create an ugly beam (unless diffused properly)

There are 5000k and 6500k flavors. You may believe or not, but the quality of light is so high that I dont hesitate to use the 6500 version at night. Before that I would never get anything cooler than 3500k

I have tried both a 4000K and a 5000K Optisolis, and personally prefer the 4000K (of the two particular emitters I happened to receive)

Be aware that the CCT alone does not completely define the tint. (Note, I am replying here to @properstranger not @matumba)

As an example, I recently received an Emisar D4V2 with SST20 (4000K / 95CRI) emitter, which I found too green :(

Sorry for the delayed response but I'm not ready for custom builds, just looking for an off-the-shelf 1x18650 or very small 1x21700 that has a tint just a little whiter than my new ZL SC53w. So far it's my favorite but when I realized there were high CRI in 5000K I thought I that might be sweet spot for me. And thanks @archimedes for confirming the CCT alone does not define the tint. After some more digging my top two candidates are the ZL SC600Fd Mk IV Plus and the Acebeam TK18 CU (219C). I'm leaning towards the Acebeam because it will also take CR123A and looks pretty sharp, but both are very pricey for my budget. Any input on these or similar ones?

CCT determines the amount of red vs blue in the light spectrum, while tint determines the amount of green vs magenta. This is grossly simplified, but in short is mostly accurate.

Most common high cri lights that are 5000 or above are going to be running 5000k 219Cs, and those are mostly hit or miss on their tint-- lots of reports of yucky greens.

If I were getting myself a 1x21700 5000k high cri light, I would go for either a Zebralight SC700D with its XHP70.2, or a Fireflies E07 with 219B SW45Ks. (I know the SW45K is listed as 4500k but it looks more like 4700ish or so and is rather white when I compare it to my 5000k Catapult V6.)


The E07 with SW45Ks is definitely going to have a better tint to it, but the Zebralight is sporting a more efficient driver and way more modern LED. Both are going to have a turbo around 3000 lumens, while the Zebralight can run 900 lumens flatly regulated for 2 hours, and the E07 can run around 700 lumens flatly regulated for a couple hours as well. Both are decently compact for 1x21700 lights.

Not sure if that is a typo, or misunderstanding, but as @twistedraven also points out there are a lot of tints *off* of the ideal Planckian locus.

I couldn't find an E07 with 219B SW45K. How would the 219B R9080 compare? How does the Zebralight SC600Fd compare to the SC700D tint wise? Thanks.

I'll keep an eye out for them, thanks. Looks like the TK18 is on pre-order from illumn.com now with LH351D, but 6500K.

The 219B R9080 is the 219B SW45K. R9080 stands for cri qualtiy: minimum 90 cri 80 r9 (r9 is deep red). SW45K is Nichia binning terminology: SW45 is 4500k, and the K stands for extra rosy. When most people measure the SW45K, they measure 94-98 cri.
