What did you mod today?

Convoy S2+ ‘Shake&Bake’.

I had this sitting in the packet in a drawer for ages, so I did a ten minute mod on it today to try and make it a bit more interesting. Shook it in a plastic bottle with sharp stones, rubbed it on the stone paving, gave it a scrub on a big leather knife strop to knock off any dings and wear the ano a bit more.

Baked on the kitchen gas stove for a few minutes until the black ano turned coppery.

Nice work! The 519a Dedomes look great with the D4SV2 optic.

Nice distressed look RichH and it looks like the baking turned out pretty even between the body parts!

Much appreciated bobvoeh this combo is a great set-up beautiful tint and great output

Ok, this is what I’ll call my first real Mod. My previous ones were new S2+ Triple builds. This is the first time I took a completely good flashlight apart and swapped out the emitters. It came out great. It started out as a Emisar D4V2, standard driver and Cree XP-L HI V2 5D 4000K emitters. I swapped out the XP-L’s for Nichia 519a 2700K with domes. Man, those little wires are a pain to route. For the main LED wires, I soldered longer 22ga wires to fish them through. I didn’t have anything smaller so I couldn’t do the AUX wires that way, but I was able to feed them through as is. However, once assembled, I couldn’t tuck the blue and green wires back down all the way, so I had to just make them fit.

This is it back together.

AUX work (yes, it cycles through all colors :slight_smile: )

I’m thrilled that it all worked once back together. Now I just need more practice with the smaller wires.

Yeah, those tiny wires can be a handful. The good thing is it worked when you were done! Great stuff!

Looks good bobvoeh! I’d have a hard time taking apart a perfectly good flashlight. If it had green tint, then no problem.

I was thinking that some Teflon wire (like these from MTN) would’ve been perfect for the AUX LEDs. It’s a lot smaller than silicone and much more rigid. I’ve used it with some of my mods.

How do you like the new LEDs?

1 Thank

Yea, I’ve been looking at the Teflon wire as well as the Enamel wire for something thin. I love the new LEDs. Now I have two pairs of 2700K and 4500K 519a’s. I have 2 D4V2’s now, one I bought with the 4500k and I have 2 DT8K one with 2700k and one with 4500k. When I’m trying to find something, I like 4500k. For me, small things I’m trying to find seem to pop out at me better. For just seeing in the dark, I like the 2700k.

Teflon wires are stiff and a royal pita.

Y’all can’t imagine how many brand new expensive lights I’ve disassembled! Lol

I’ve ordered a great many knowing I was going to mod it right out of the box, usually without ever even turning it on first.

Congrats on the mod, bobvoeh. The D4V2 was my first really intimidating mod. When I did a dual channel version I think I ended up slightly enlarging the center hole on the mcpcb to help manage all those wires. I need to do it a second time, which I’m dreading, since I still don’t like my emitter choices.

1 Thank

I’ll remember that about enlarging the hole. That’s a good idea.

Careful enlarging that hole, fairly easy to short the board, cut a slight bevel with a knife or a blade on scissors, this separates the layers and lets the dielectric layers divide your traces. :wink:

Thanks. I gave it a good long burn on the gas stove, both ends took way longer to change colour. I suspect the thicker metal, plus the heat from the very hot tube being less able to conduct via the threaded parts, is a possible cause of the uneven colour change I’ve seen on some baked finishes. I really got that thing glowing hot and kept it moving in the flame.

If you want to practice find a lume1 aux board :grimacing:
Nice work man! Xpl-hi are very efficient but you can reuse in another flashlight

Thanks Light Veteran. I agree, I need to find something like that so I can practice on the small things. Those XPL-HI are very efficient. I put them in the piece of reel the 519’s came in for safe keeping until I can repurpose them.

They are rosy or not?
Second batch of Hank xpl hi was not rosy and I sell my D4V2. I think is 2021 or before

No, not rosy, but not green either. Pretty much on the BBL, very neutral.

0.00013 is upper bbl but very close. If you don’t see greenish tint your are lucky
