FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

Just got an Emisar D4 with 4000K 95 CRI SST20 installed.

The beam looks beautiful. I think even superior to my previous favorite XPL HI 4000K.

Might have to get some of these to swap into an FW3A.

Hank has a great price on the SST20's - $1.58 each, qty 10.

Link please??

hi ,
Checking in, it appears there is a decision to be made.
my numbers are 739, 740, 889, 890. could you make it two of each emitter? thank you. Andy

Thanks KB, ad there's more. Hank just emailed me with the part numbers of the low CRI versions:

SST-20-WCS-A120-L3652(L3-VL-BA) 6500K

SST-20-WDS-A120-L2501(L3-VK-DA) 5000K

I asked him to post on the website, we'll see. I got in the 5000K's for their better throw and output, so that DA tint I'm glad to see.

I would assume their the same SST-20's he's using in the Emisars. I email him at contact@intl-outdoor.com, and seems to get back pretty quick, might be an hour or day or two.

Is he sure that the 5000k emitter is a L3 flux binned part?

The datasheet says that the L2501 chromacity bin is a L2 flux binned part with a chance of getting the DA tint bin, which seems good.

Thanks for the info KB & TomE.

@ TomE…. Excuse my ignorance, but what is the DA tint you mentioned?
What does the ’DA’ signify??

I dunno - maybe ask him. He first told me they were L3, then I asked for the other tint info and that's when he gave me the part #'s.

Doesn't KD sell them here: http://kaidomain.com/Flashlight-DIY-and-Tools/LED-Emitters-or-LED-Star-on-PCB/Luminus-Leds/Luminus-SST-20-L3-DA-Neutral-White-5000K-LED-Emitter

They got a pic of the label.

Blue knows more bout this than I do, but from the SST-20 datasheet, the DA and DD tints are at or below the magical line thing...

@TomE, good god you made me laugh. Magic Line thing. That’s a first :laughing:

Well, the DA tint bin is precisely what it sounds like: the color tint bin, or how the beam of the light tends to go to a certain color, being red or green, below or above the curve.

The magical line you see is, simply put, the black body line. A perfect 100CRI light source will be on this line, every time. Otherwise, it might actually drift to slight green, or slight red.

Slight red is preferred by most people since it looks more saturated.

OK, thank you Tom. :+1:

Thanks Blue!! So the ’DA’ is on the slight red side. Right??

- that about says it all about that...

@teacher, did not even recognize you initially. Thought someone else jumped in.

And yes, that means most of the LEDs will be on the slightly red side. At 5000k, you won’t be noticing it much, so it’ll pretty much be a pure white starting at 200-300 lumens rated.

Yeah…. I changed to a more neutral avatar when the real meaning of the other one was brought gently, but very effectively; to my attention. :wink:

But, moving right along…. Thank you for the info & verification. :beer:

FWIW, I put some pictures in the OP to provide a color reference. I hope it gives people a decent idea what to expect the light to look like. Basically, scroll down a bit or search for “color ref”.

I for one, REALLY like that darker gray tone.
N O I C E!!

I’m listed for qty of 2 … now I’ll commit to 1 of each emitter please.

It seems like a decent color reference, but more distinctly, it makes me crave a rainbow-anodized titanium version. :+1:

You’ll probably have to talk to Rey (WWEFANS) about that. I still don’t know how exactly he got a rainbow-splatter finish on the Ti Dawn:
