Hard pass. CRI99 or else 
CRI99? ā¦ sounds like you want an old incandescent maglite!!! :sunglasses:
Reminds me of the old incan Solitaire. Max output was 2 lumens (though I think even that was optimistic), and the light was zoomable with 2 modes:
- āSpot modeā - this put a small dim spot of orange light. Sufficient for illuminating something 3 feet away, such as the keyhole of a door.
- āDonut modeā - this created a thin orange donut-shaped ring of light. Very dim. Not useful for anything.
which emitter?
I ordered the 5000K xpl. So it should be nice and bright but still neutral.
Using turbo doesnāt somehow disable the lightās built-in LVP. There might be protected 18650s that could handle the drain from a D4 on high or turboā¦ but they will be rare and probably expensive. No protected 18350 will be able to handle the higher output levels without tripping the protection circuit.
Iām not even sure most protected cells will fit a D4. For kicks I checked if a Wowtac 26650 (flat top, protected) would fit my D4S and it was too long (wasnāt going to risk crushing something by forcing it).
Sorry, that is what I meant originally, current draw. I would rather have the cell protection trip and be annoying than damage an unprotected cell. If I canāt find one that could handle the current without damage.
18650 Battery Store has a Samsung 30Q with a 15A protection circuit. Still would not fit because it is listed at 68.64mm, which is a bit too long. I know you were talking about an 18350 but I havenāt seen many protected batteries be able to handle higher current.
I will just have to be careful then, thanks!
Iāve noticed that most optics that have data from Carclo/Khatod/Ledil or whomever, always seem to have unfavorable results with the E series nichias. I wonder how much of this has to do with them being so thin and domeless, resulting in them sitting too far below the optics? Has anyone tried drilling (counter-boring) the mcpcb holes to see how the optical efficiency and beam change with a different focus?
I wonder if they made the KR4 with a buck driver if the efficiency would go up substantially.
This light looks like a great alternative to the FW4A. Anduril software is fantastic.
Are there sources to order these from in the USA, or only from China?
Is Intl-Outdoor a good source for these?
I can vouch for Intl-Outdoor, placed many orders and never had a problem.
Itās Hanks own store so fully legit and you will be looked after.
Thank you, x-ray! Good to know. I will order from Hank.
Looks very nice, but a little pricey.
Just ordered from Hank, with Warm White - SST20 3000K 95CRI. This will be my nightstand flickering Candle light. Thank you ToyKeeper for this awesome UI.
Iām not sure if there are any diffusers which fit, but ceiling-bouncing it can be nice sometimes too.
However, tail-switch lights in general are a little awkward while ceiling-bounced. The button isnāt accessible in that arrangement. So for a bedside light I usually go for something with a side switch instead.
Diffuser added to fw4a package shall fit. I think this is the same as the one for fw21a that can be found on aliexpress.
TK, yesā¦ it will be ceiling bounce in candle mode. I can see the utility of the side switch for tail standing, but Iām ok with the tail switch - no problem picking it up to adjust.
Thank you. I will have a look for that.
FW4A diffuser will fit the KR4?
Yes. If you take a look at head diameter fw4a is 28.5mm vs 29mm of kr4.
