Some people notice some donāt . I am totally with Zak on this one.
Outdoors, especially when you try to distinguish colours and to estimate depth, the hi cri really shows.
Itās why I always take a hi cri with me when I go running after sunset.

I want to buy one. This sounds great! Thanks
TK, what CRI or color temp is the SST20?
That pic is showing ~4500K next to ~4000K.
According to RobertB, a weak Lee minus eight correction filter helps reduce the green on the 3D. His beam shots earlier on look terrific. Have you tried using any correction filters?
That SST-20 is :confounded:
Please do not value tint pics so much, they are always off and there is always someone who bases opinions and even buying decisions on tint pictures, which is silly. No SST-20 4000K 95 CRI I have ever seen in reality looks remotely so green.
(and this is not because I prioritise CRI over tint )
Should I believe you or my lying eyes?
Following the CRI discussions here, I also ran a few tests of my own. I pitted two Convoy S2+ flashlights against each other, the only difference being the emitters used (XP-L HI 4000K vs SST-20 4000K).
On a white wall, the tint of the XP-L HI was far pinker than the green SST-20. This isnāt so much a real-world concern however, so I decided to ignore the differences in tint and focus on the CRI aspects of each emitter.
I took the flashlights outdoors last night and let them rip across a field. Both emitters have a very similar amout of throw in the S2+, Iād say around 250m, so it is a pretty fair comparison. With all the grenery, tint wasnāt much of a concern any more, so I focused on trying to make out details in the treeline at roughly 100m and 200m distances. I supposedly have perfect eyesight, but Iām sad to say that I couldnāt see a bit of difference between the two, except for maybe the greener SST-20 looking a negligible shade cooler than the pinker XP-L HI. When I walked right up to the trees, the SST-20 did make the tree trunks look a little bit more saturated in colour, but honestly the difference was pretty minor. The XP-L HIās 70 CRI was still more than enough to easily distinguish colours. No issues spotting where the branches ended and the leaves began. Nothing looked particularly washed out in comparison to the higher CRI emitter. A bright red car that I passed on the way back was probably the biggest difference I spotted. It looked fine under the XP-L HI, but popped a little more under the SST-20ās high CRI light.
Itās odd why some peopleās eyes are really sensitive to CRI, and othersā arenāt so much. Donāt get me wrong, if all SST-20s had the same great tints as most XP-L HI emitters then Iād pick them as a favourite, but I just donāt feel that the efficiency, heat and tint tradeoffs are worth it for a difference I barely percieve in real world usage.
Itāll be interesting to hear the results if someone more CRI sensitive than I were to perform a similar test.
/\ ā¦ Where did the picture come from??
they look great!
That sand/oiled bronze/gold color is fantastic!
yes, i wish my grey ones were that colour. Unfortunately a different colour is not enough for me to buy more FW3Aās
I think that here at BLF most just forget that this is a collaboration between TLF and BLF.
So there are efectively TWO comunities ACTIVE for this flashlight.
Seems that the communication is one direction these days?

Agreed. That one is a winner in my eyes. I like the others but I donāt see them having as much ātimelessnessā as the bronze.
Blue got the most votes on TLF, next is a tie for olive and white ...
There will also be a 100 pieces limited run of a 'special purple ToyKeeper version'!
Wonder how they are going to do that with orders coming from TLF, BLF, Neals Deals and Max Deals, ...!?
Surely hoping TK is getting one!

I canāt recall the source unfortunately, but some years back Iād read a medical paper (geared toward the lay person) about the human eye and differences from person to person. Essentially, we all see color in the same way, except that some people suffer color loss (blindness)āeither fully or partially by segments of the spectrum. So it may be possible for some people to perceive saturation a little differently, but the tint doesnāt change. However, the greatest disparity is the braināhow we process color. It is rather subjective by experience. This āskewsā the input from the optical sensory organ. And also, the perception of color will vary depending upon taste. Some people may be put off by some colors that makes them more noticeable, while there will be some colors with a more neutral effect (no emotional impact one way or another). I donāt know if that is inclusive of āCRI sensitivityā. And lastly of course, is how the brain interprets tints when multiple ones are visible. This is why one tint can be OK and then look lousy when itās next to another. Anyway, it all comes back to one thing: subjectivity.
Last but not least is the CCD sensitivity, color and whiteness balance of the camera taking the beam shot photos. That also complicates perception. Despite all this, the beam shots are most useful with simultaneous comparative display, so the relative color is captured under the same circumstances.
How do I reserve myself one of the limited edition purples?
Honestly, I really like all the colors. The white looks quite good, and reminds me of a few other lights in white that Iāve quite liked. The āsand/oiled bronze/goldā is very nice. And blue is just plain popular.
Just last night, someone sent me this about my love of purple:
Prince explained the meaning of āPurple Rainā as follows: āWhen thereās blood in the sky ā red and blue = purpleā¦ purple rain pertains to the end of the world and being with the one you love and letting your faith/god guide you through the purple rain.ā

I don't think you can and that wouldn't be fair at all.
Sounds logical to me that only TK is in the position to 'reserve' a limited purple piece for herself (she also has the connections)
Maybe ask her ...
