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

Cool just been back into this thread after a few months away and looking at the updates has me well um Excited looks really good and I just want to make sure I don’t “miss the boat”

In for one! Thank you!

Excited to swap Luxeon Vs into one...

I am 192…please put me down for 1 more (2 total).

When I put some in a E2L with 10507 the starburst shaped hotspot is very noticable to me. I personally am not too bothered by it but I dont think I would say virtually disappears.

Sign me up for 1 please.

Please put me down for two more.

Nope, I already asked about the color some pages back, it’s not like it’s graphite gray or something (sadly ;D) – see TK’s reply:

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:
