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

I like this design.
Oh! Fritz first design, well
Now I, see it better.

You know, I just realized that this is likely the same size as an hds that uses cr123 batteries!

I just sold my hds rotary. That should give me enough $ to buy about 5 of these!

Yes, it is about the same size as some older CR123-based lights. I see 94.0 x 25.4 mm listed for the HDS Rotary CR123, and the FW3A is 94.8 x 25.5 mm. So almost identical size, but it uses 1x18650 instead of 1xCR123. Much greater battery capacity and much higher maximum brightness.

This light is the perfect size and the added bonus of how programmable the driver is, think this might find a new home in my pocket.

I would like to get in on this and order 2.

Interested

For maximum brightness, use a large rubber band to bundle all 5 of your FW3As together…… 15,000 lumens in the palm of your hand!!! :stuck_out_tongue:

Some questions about the LH351D…

  • Is it available in high CRI 5000K, or only warmer?
  • How does the beam look in a 10511 optic?
  • How many lumens / candelas does it get in a 10511 optic?

More generally, I’m trying to fill in a comparison table accurately. Any corrections or extra info would be helpful.

Can’t answer these, but may I suggest to consider - at least on a “trial” comparison - the Luxeon V ?

Thanks for the efforts on this!! :+1:

● it does exist, the datasheet says 90CRI goes up to 6000K, and there is a 5000K 90CRI one at Digikey: https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SPHWHTL3DA0GF4RTR6/1510-2334-1-ND/8568350

● I only have them behind a 10507 optic and that looks good: big smooth hotspot (1.5 times the size of 219B in that same optic), despite the large die no weird squares like XP-L Hi.

● no idea, the die and dome are quite large so the optic may not be as efficient as with small leds, and the light is very spread out.

The triple 10507 optic light (Jaxman E2L) with 4000K 90 CRI LH351D on an Aspire 18350 cell does 1800 lumen, on a 18650 cell a bit more, but you loose a bit again with the frosted optic.

In general in your table the outputs are optimistic, in a small light like the FW3A you only get such numbers in the first second, maybe.

I’m really not sure how many lumens to expect from a high-CRI LH351D triple, compared to other options.

I would like to purchase one of these. Please add me onto the list.

The list will be updated later
I’m sorry, now I’m with the smarphone (Mobile phone),
and I need the PC

I expect 4000+ lm with LH351D CRI70 5000k, 3400+ lm with LH351D CRI90 5000k in a clear optic. 12A current draw. For 10511 CRI90 prediction drops to 3300+, CRI70 stays.
Warmer tints are less efficient. These numbers are rather conservative, mostly because current draw should be higher.
1.5 cd/lm with 10511 and 2 with 10507? That’s very imprecise.

ADDED:
If LH351D was to get dedomed, I’d say:

  • CRI70 5000k 10507 3300+lm, 3.5 cd/lm
  • CRI70 5000k 10511 3300+lm, 2.5 cd/lm
  • CRI90 5000k 10507 2800+lm, 3.5 cd/lm
  • CRI90 5000k 10511 2800+lm, 2.5 cd/lm

I have a triple samsung 4000k in a Convoy S2 mod. They are very nice and give a huge hot spot. I have to get which optic and specific emitter are being used. Not as pink as an XP-L Hi. Would find these to be an awesome choice for this light! Extremely smooth beam and minimal weird outer distortion.

I’ll take one

Guys, it’s way to early to actually produce this light. It was predicted for 2018. To have it produced before 2019 would be to shatter reality as we know it.

Hmmm…. Why do you say or think that??

I'd like one depending on the final price. Thank you for your good hard work!

I’m liking the look of the Samsung LEDs just because they won’t run as hot as 219Cs and kill themselves.
I also like flood. :+1:
