    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)

    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.

    typo, thanks, original post corrected.

    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've fallen in love with the LH351D LEDs lately. +96 CRI. Both 4000k & 5000k. If you haven't checked them out, I suggest ya do.

    Sent from my SAMSUNG-SM-G900A using Candlepowerforums mobile app
    I Got tired of looking for the light at the end of the tunnel so i lit that bitch up myself! Convoy s2 365nm, Maxa-Beam Gen II, 55w hid/100w incan Vector Twin, Amondotech n30, vss-3A, Reylight Ti Lan v3, Helius Sigma 9, astrolux s41 219, Shadow JM35, BLF GT,

    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.

    Thanks for the explanation. That sounds like what I'm looking for, just wished the head was smaller.
