5050 leds on 3535 mcpcb

LED Flashlights – General Info
1

Hey, everyone! I’ve been out of the flashlight game for a few years but this past year have gotten back into it.

I’m working on a mod and need to know if the new 3v xhp50.2 leds (5050 footprint) can be mounted onto the 3535 mcpcbs. I seem to recall others doing it in the past but can’t locate those posts by search. I have an older triple xm-l2 light I want to replace with xhp50 but the mcpcb is aluminum and I would like to use the triple 32mm Noctigon mcpcb but it looks like they are only available with 3535 pads. Can I securely reflow the xhp onto this or, if not, does anyone have an older 5050 version laying about they can spare?

Looking forward to your responses.

Hi JohnnyMac!
Welcome back :wink:

I am not sure if this will help in your quest, but take a look:
https://asflashlights.com/mcpcbs/136-sinkpad-copper-mcpcb-for-cree-xm-l2-xh-p-50.html

It is sold in vestureofblood / aka Matt Smith / aka AdventureSportFlashlights, in the US so maybe you can check with him!

About the 5050 to 3535 I am not the best person to talk about that sometimes I can’t even reflow a 3535 correctly :smiley:

Good luck :wink:

Hah JM!! Hope all is well!

5050's on 3535's doesn't sound familiar to me, but doesn't mean it hasn't been done. Hhmm, a 32 mm triple XM is probable something I don't have.

check'n some specialty shops:

Not here: https://www.virence.com/shop?Collection=Metal%20Core%20Printed%20Circuit%20Board

led4power's website is not working for me: https://led4power.com/. Might be a long shot.

Problem is any of the new MCPCB's are for new LED footprints, like the 3030's or 4040's, so not much goin on with 5050's. The XHP50.2 3V and SST-40 though are both impressive new gen LED's.

Here's one at Cutter: https://www.cutter.com.au/product/mcpcb-xml_xhp5032_tpad/, but as you probably know, shipping can kill the deal.

Holy cow, it’s JohnnyMac! When I saw your name I figured a thread got necro’ed. Nope, JM got necro’ed! Welcome back sir.

MascaratumB, that appears to be exactly what the doctor prescribed. Will hit up VoB and confirm it works with the Ledil Cute3 optics. Thanks a bunch for the tip and the welcome back.

Everything is great, Tom. Hope all is well with you, too.

I’m not above ordering from Cutter, have in the past but it looks like as flashlights has what I need. Good to have a backup.

Glad it helped :wink:
And we’ll be looking for the mod :smiley:

It should be a good one. It’s an old Olight SR Mini Intimidator. Replacing the driver with a 26mm mtn FET+1 running Anduril and installing shaved xhp50.2 3v LEDs. hope to be making at least 10k lumens. Should be a fun project.

It's good to see you again, JohnnyMac.
