Emisar D3AA is available now

I’m thinking about grabbing a cyan D4V2 with E21a and the 18500 tube, a first for me.

Is 3.8 amps from a Panasonic 18500 enough for E21a to do it’s best?

[lightdecay]

Is there a trustworthy review for that 18500 battery?

Based on the review, this Vapcell 18500 would be good enough for E21A to perform at its best.

Thank you, I wasn’t aware of that review. Admittedly, today is the first time I’ve entertained 18500, so knowledge was very limited.

Thanks again!

Hello Hank,

Can you get Osram KY CSLNM1.FY (yellow) emitter for Noctigon K1? As there is already green and red variant, I think, yellow is at least that useful, if not more (I would love one in my hands, to be honest).

Green KR1 next?

There are 18650 and 18350 version D4V2 cyan in stock, there is no 18500 cyan tube in stock.
You can choose black, grey, or sand color 18500 tube.

Hank, do you still offer custom built lights with SST20-DR in 670nm deep red wavelength? Someone reported that you were able to source a chromaticity bin with 670nm instead of 660nm (the more common wavelength available). Thank you! :-)

@battery

Green KR1 next?

^ yes please!!

[ArtieT59]

I am SO GLAD I haven’t bought the K1 yet, because now I’m going to! I’ve been scanning everywhere for a Green Emisar/ Noctigon… anything. I missed my opp with not ordering the green d4sv2 when I first started this hobby and didn’t realize they’d run out and never return. HANK- thank you! Amazing look on both the d4 and K1. Here goes another 2 bills…

Hank. PM sent about flashing kit with flashlight.

I posted that, but the information was wrong, so I edited that post.

670nm deep red led helps eyesight

Hank Wang from https://intl-outdoor.com/ just told me that his SST-20-DR leds are 670nm for now. I don’t know if that number was measured or if it is the manufacturer bin. SST-20-DR is advertised as a 660nm led, but according to the data sheet it has 6 chromaticity bins, between 640nm and 670nm. https://download.luminus.com/datasheets/PDS-003040-Rev-04-SST-20-DR.pdf You can order a custom Emisar or Noctigon flashlight from him with SST-20-DR leds if you email him. Emisar D4V2 and Emisar D4SV2…

Once Hank received them, it turned out that they were actually SST-20-DR-B120-V660 Flux:X Voltage:V6 Color:D5. D5 is the 660nm-665nm chromaticity bin.

That’s still a higher peak wavelength bin than C01R XP-E2 Photo Red with P3 bin, which is the 655nm-660nm chromaticity bin.

Sofirn C01R deep red [sold out, discontinued]

Small update (2020/05/26): The actual LED bin code of the sales version is XPEBPR-L1-P30-29, not XPEBPR-L1-P20-30. The difference is negligible. On paper the prototype had a dominant wavelength of 650-655nm and a slightly better radiant flux (450-475mW @ 350mA), the final version uses 655-660nm and a slightly worse radiant flux (425-450mW @ 350mA). Since this flashlight's objective is to have a nice deep red beam quality and not lumen records, I consider this minor change as a benefit. [image…

That’s fine, Hank. I don’t actually need it. Not a big deal at all.

I’ll just take the 18350 tube. Easier to find good batteries for it anyway.

Just ordered a green K1 with the XHP35HI 4000K.
Should look good next to my dark gray K1 with the W1 (Osram CSLNM1.TG), 6000K, and my black K1 with XP-L HI V2 5D

Green KR1 next?

^ yes please!!

I would definitely buy one!

I’ve been resisting the urge to get a K1 with XHP35HI but think the green version may have given me the final push :person_facepalming:

Look forward to seeing your comparisons :+1:

[mbp]

Did I read somewhere that Hank was getting LH351D 5000k 90CRI? I don’t see it as an option for anything. Would definitely pick up a 4th KR4 with that if the bin is nice. 4000k would be even better. I really like the Samsung LED in a nice tint bin.

Yes that green is pushing me over the edge soon. No idea about what led I should get with that. Osram or good old XHP35 HI. Hating Osrams tint, but it gave more throw, about how much?

From intl-outdoor.com :

W1 (Osram CSLNM1.TG): 900lm, Lux : 650Kcd (650,000cd)
W2 (Osram CSLPM1.TG): 1400lm, Lux: 550Kcd (550,000cd)
XHP35 HI 6500K/5000K: 2000lm, Lux: 290Kcd (290,000cd)
XHP35 HI 4000K/3000K: 1800lm, Lux: 270Kcd (270,000cd)
SBT90.2 LED, 5700K, 4500lm, Lux: 420Kcd (420,000cd)

And from people more knowledgeable than me on BLF, it seems Hank’s #’s are to be trusted.

[Aaron93]

Has anyone measured the CRI of Hank’s 2000k? Just curious if it’s R9080 like Clemence’s batch was.

[hinbli]

The intl-outdoor website indicates 2000K is with R9050 for E21A. I don’t remember if anybody has done the actual measurement. If I find it, I will report back.

I have got a question related to E21A, too. I have KR4 with E21A/5000K. Does somebody have a picture of the driver for KR4 with E21A? I understand that the driver is the one with 5A max, unique to this LED. I would like to see how it looks like.

Thanks.
