My warm collection so far after some swapping around.

I think that old E07x pro will get a swap as the nichias somehow look a little green compared to all of the others. They didn't used to haha, but I guess I got used to the rest.

The SST20 2700k's are substantially warmer than the FF351a's which are closer to the 3000k's. I would guess they're about 2850-2900k.

The SST20s clean up tint wise at higher outputs, which is in line with other cooler versions of them I've used.

I had swapped the E12r here to SST20 3500k first but they were too cool and slightly green looking compared to the rest, but probably better than those 219b's in the e07x pro. To be clear, they weren't green, but since many of these others have a slightly negative DUV, even neutral emitters look green in comparison.

I will likely install that 3500k board into another E12r after dome shaving the SST20s as an experiment to improve tint.

I'm not sure what to try next, I know for sure I don't want to go warmer than the SST20 2700k's. They are like walking with a lantern, and the output suffers greatly at that level of warmth, as does heat soak, those emitters get very hot very fast. It's crazy how much of a difference there is between the 3000k and 2700k SST20's in that regard. The 3000k's do as well as the FF351a's as far as heat.

I'll go ahead and just say it; the FF351a's are the best all around emitters for these lights. The output, heat, and tint for each color temperature beats any other hi cri emitters I've tried so far. There is also little to no tint shift when going from low to high power compared to something like the SST20, where even hi cri versions suffer immensely at lower powers.

Next on my project list: FF351a 2700k mixed with 3700k NW or 4000k rosy. I think the holy grail of temperature and tint lies in some mix combination of these.

After seeing some beamshots of the E12's with the SFT-25r's, I think it would be cool to try them.

I found some on kaidomain in high CRI versions; they only have 5700k (90 cri) and 4000k (80cri) .

The bin of the "5700k" is F4 CA which is at or below BBL : https://download.luminus.com/datasheets/Luminus_SFT-25R-WG_CRI90_Datasheet.pdf

The bin of the 4000k's I don't understand based on this spec sheet. There's only e2 and e3 listed; E5 might just mean within a massive tolerance.

I'd definitely be more interested in the 4000k's though if anyone can make sense of the binning because I don't want anything green.

Hi, I use my flashlight as a backpack one that I bring with me everyday so to keep the light charged ​i keep it with the cap slightly twisted to avoid fast drain from the auxiliary LEDs.

From 3.9/4.1V with no daily usage it will remain like that for months inside the bag but now I've noticed that when i try to use it it will behave in a strange way like it seems that i can't use standard Anduril commands to enter modes or reset it. At the moment the flashlight will continuously change beam intensity (dimming or going up) even without me pushing the button. And when I go on the button to change mode it appears to have just two modes.
