[GB ended, news update only] Last batch of 219B sw45k R9080 and sw40 R9080

Yes that’s it, 3x E21A 2000K on 3x VR16S1, one LED per board. Thanks!

Did the 219B 4500 & 4000 go out-of-stock? I was finally going to order 6 of the 4500 & 3 of the 4000 reflowed on 3 noctigon 3XPs.

Check the OP Steve

I’ve been thinking (and reading) a lot, and while I thought the 4000k might be just too warm for me, I really should get a mix to try.

So if I may, I’d like to update my 15 emitters from all 4500k to: 9 x 4500k and 6 x 4000k.

Thanks again, and sorry for changing up my order.

Oops

I checked and you have my order correct but BLF username may not be in pp sorry.

For reference its

8x45
2x40

20 4500K

I would like:
5 x sw40
5 x sw45
Intl shipping $5

Paypal total coming: $33

Clemence, Please ignore my PM. This is my slightly reduced order:

I would like the following 219B LEDs on Noctigon MCPCBs

details of five reflow services in total:

Three Noctigon 3XP parallel only 6A configured with two 219B 4500 and one 219B 4000 each MCPCB.

One Noctigon XP16 single with 219B 4500.

One Noctigon XP20 single with 219B 4500.

My order cost is detailed next. in USD to be sent to your paypal:

eight 219B 4500 LEDs @ $2.80 each = 22.40 USD

three 219B 4000 LEDs @ $2,80 each = 8.40 USD

five MCPCBs:

three Noctigon 3XP @ $3.00 each = 9.00 USD (parallel only).
one Noctigon XP16 1.85 USD.
one Noctigon XP20 2.00 USD.

five LED reflow services three .70 each and two .50 each = 3.10 USD

Postage to USA 5.00 USD

total 51.75 USD

All correct

Do these SW40s and SW45s share the same Vf bin/voltage performance group? Hope they're at least quite close for an about even load distribution; if not, in series is the way to go.

Cheers ^:)

No, they don’t. There’s always slight difference between LEDs, even those came from the same reel.
This is a makeshift solution practice which is not ideal but works OK. In real world practice many flashlight makers do the same. Some uneven brightnesses can be seen in ultra low firefly modes.
Low LED thermal resistance, high thermally conductive MCPCB, and careful soldering (thin solder joints) lessen the problem.

- Clemence

Send payment for 1x sw40 and 1x sw45 more, total 6+6 (was 5+5).

Really hard to calculate how much I need for all my flashlights…

The GB will ends tomorrow, please kindly re-check the gsheet. I will stop receiving orders in 180604, 00:00, GMT +8 (~26 hours from now)

Thanks,
Clemence

Clemence,

Not sure if you saw my change above, it is not on the sheet yet:

I’d like to update my 15 emitters from all 4500k to: 9 × 4500k and 6 × 4000k.

Thanks again for doing this!

Clemence; Just covering my bases. Hopefully can find a good driver for this.

Pls add one more noctigon 3X in series ($3.30) plus two 219B 4500 and one 219B 4000 ($2.8 x three = $8.40) and reflow service for same (.70). I’m sending $51.75 + $12.40 = 64.15 USD

9A for this one. would work?

sending now to
virence.cle@gmail.com

9A and you're asking if that would work. That depends in what you believe “to work” is. For emitters who start tapering at ≈4A when properly cooled, if “to work” is to witness Mr Magical Smoke that will work.

My guess is you probably meant to say “3A” or “Noctigon 3X parallel”. That fixes it.

Cheers ^:)

2x 219C sm303 D200 R9050 = 7 $

Shipping = 5 $

total = 42,80 $

Hello, may I please make an order?

I would like 10x of 219B sw45k:
3x reflowed onto Noctigon XP32 in parallel configuration
3x reflowed onto Noctigon 3XP [parallel only]
4x reflowed onto Noctigon 4XP v.2 [parallel only]

Costs:
10x 219B sw45k = $28
XP32 = $5
3XP = $3
4XP v.2 = $3
3x reflow service = $2.10 (is this the correct price for reflow?)
USA shipping = $5

Total = $46.10 (please advise if this is correct before I send paypal)

Thank you!
