What did you mod today?

I haven’t worked out the “schematic” to see if it’s doable, but one of these


might be able to be used as a contact board. Solder a small spring or nipple to the center pad (isolated or connected to something I have no idea), got the 2 electrically-connected pads on the side (for those “bead” type LEDs), and wire up something appropriately to use that to solder to the board with the 9 LEDs on it.

Of course, insulate appropriately with plastic sheet cut to fit, etc.

It’s possible to do a cut to isolate plus, then wiring the IC, then pot everything with epoxy.

This board is interesting, too :+1:

Thanks Unheard. I found that searching for ‘12 LEDs UV flashlight’ on AliExpress brought up many listings for that light (or one that looks just like it), including some in different colours (blue, silver, and red). I’ve already ordered a couple from different sellers to try out.

You have to watch out for the the cheaper 9 LED version that’s in many of the listings - it looks just like the red one in my photos which is absolute rubbish.

As contactcr mentioned, some 3 x AAA lights will fit an 18650. I’ve even used a 21700 in one. However, I’m happy with the 3 x AAA in a low power light like this.

Thanks pc_light, that description is excellent. I hadn’t realised there was a lens over the optic - I assumed that because it was plastic it was a single piece like in the later production FW3A.

Just modded the lanyards of these two lights! I think I will call these “poor-man-lanyard-without-tritium-in-titanium-bead-but-with-GITD-fob-embedded-in-paracord” the “”Firefly style lanyard”:https://www.google.com/search?q=firefly&safe=active&sxsrf=ALeKk02pXGvupQdmyHYd0BcLF4UsC8okUA:1591916185235&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi7ou717frpAhVuyoUKHVPYAeUQ_AUoAXoECCAQAw” :smiley: :student:

Not the best looking, but it was the possible work :partying_face:

Nice work, MB! Did you make the GITD fobs? CRX?

Thanks gchart :wink:
Yes, I got them from CRX, I forgot to mention that :person_facepalming:

The aqua blue one already arrived with the split ring “embedded”, while the orange one (that arrived during the OL Contest due to the theme I had in my light) didn’t have that. So I picked 2 thin drills and added a split ring to hold it to the lanyard. That’s why they are so bulky in some parts :person_facepalming:

Great quality from CRX as ever! :+1:

I know. Some have a PCB, some only cardboard carrier for LEDs. They’re all made from sheet metal. Terrible.

Black L2P with T head. Luxeon V2 4000k
Blue L2P. LH351D 5000k 90cri with cut and polished lens. I did it first time with this led and I can say that this is the easiest led to cut to dome.
Both have “Biscotti” 5A driver.
I think I used too long copper stripe for blue L2P because I had a serious problem to push it. I hope I won’t have to pull it out because I don’t know how to do it.
I did this build before “Barkuti described a problem with ”Biscotti” driver”:【convoy】S21E XHP50.3 HI available now - #2554 by Barkuti, and I didn’t even notice it. But everything works.

Wow, great work, the look beautiful :wink:
That dedoming is top!!!

Beamshots demanded when possible :innocent:

Maybe I’ll take some pictures tomorrow.
I can’t do them on the white wall, but I’ll see what I can do in the field.

You can use plastic tubing 18-18.5mm diameter or what will clear the I.D of the battery tube, that will only contact the base of the aluminum pill and just pound/press it out…

I’m going to get such a tube… Once I used to take it out using 18350 and 18650 batteries, but this one sits so tight that I’m not going to risk it.

That dedoming looks impeccable! Did you do it for tint or beam profile?

Actually both. I was hoping the tint would get a little warmer and it happened. Although not much.

My first outdoor beamshots (blue and black).

Sorry for the blurry picture.

I like this one the best…

Good job :+1:

L2 several posts back. My first thrower. I even like it, considering I prefer flooders.

Thanks for the beamshots :wink:
I like the Luxeon V2 effect more than the Samsung , but they both look great :wink:
Well done :+1:

Looks great MascaratumB! Did the driver drop straight in? What size is it and does USB charging still work? Tempted to pick one up.
