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

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.

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!

fixed

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 ^:)

Big order:

  • 2x 219B-V1 sw45 4500K R9080 - $5.6
  • 4x E21A sm403-D220-M1-R9080 4000K – $10.92
  • 1x VR16SP4 – $4
  • 1x Reflow service - $1 (2S2P, Standard reccomended SnPb solder)
  • 2x E21A sm203-D160-R9050 – $5.46
  • 1x E21A sm653-D240-R9080 – $2.73
  • 3x VR16S1 - $12
  • 3x Reflow service - $3 (Standard reccomended SnPb solder)
  • Shipping - $5

Total: $49.71

EDIT: paypal sent!

Paypal sent for:

8x 219B-V1 sw45k R9080 = 22,40 $

3x 219B-V1 sw40 R9080 = 8,40 $

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!

5 sw45k + 5 sw40 + shipping = 33 USD

Sorry, supposed to be 24:00 NOT 00:00. So there’s still ~10 hours

- Clemence

3x 219B in series will take no more than 3,5A. 3A is the max. for highest output. If you want to use 9A then parallel is the way to go. I suggest no more than 2,5A / LED.

OK, will update your list

Paypal sent for 10x sw40 r9080

Can you put my stuff on the list Clemence if you find the time? I don’t have much time now. Maybe tonight.

Soldering service for 3x E21A on 3x VR16S1 = 3x USD 1,2 = USD 3,6.
This is the most difficult one. Scraping off the masking layer, sanding them smoothly, then positioning the LED through the entire reflow process with just enough solder to make flat and thin solder joints. Since you paid already there’s no need to send me more payment to avoid unnecessary fees from Paypal. It’s just to let you know

You are a busy man the coming period, may the Agung not distract your hard work ! :smiley:

3x reflowed onto Noctigon XP32 in parallel configuration: USD 0,7

1x Noctigon 3XP [PO]: USD 3
3x reflowed onto Noctigon 3XP [PO]: USD 0,7

Mt. Agung eruption has been a norm these days. We’re all getting used to it. And yes, I never thought the additional side orders would be this much. I probably would have to close the store for a week just for soldering.

Ooh. Good point. Can I get 4x of my sw40 reflowed onto a 4x noctigon? Is that $3.7 extra?
