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,

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

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

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

3× 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

• 1x Reflow service – $1 (2S2P, Standard reccomended SnPb solder)
• 2x E21A sm203-D160-R9050 – $5.46

• 3x Reflow service – $3 (Standard reccomended SnPb solder)
• Shipping – $5

Total: $49.71

EDIT: paypal sent!

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

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:
10× 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!

10x of 219B sw45k: 10x USD 2,8 = USD 28

1x Noctigon XP32: USD 5

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

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?

Yes that’s correct.

7 * 219B sw45k

price is 7 * 2.8 usd + 5$ shipping = 19.6$ + 5$ = 24.6$ total

I send them to your paypal now ?

Sure

Just got home from the grocery store. Will update the list soon.
