What did you mod today?

LUX-RC 371V2 with 351D?

Not bad, not bad at all sir!

I’ve always wanted to own a Sinner’s. Impressive mod, Sir.

^ What he said :+1:

I had to make a new bezel on this copper light because the focus wasn’t right. I rubbed off some of the patina with the constant handling doing the mod.

I finally got around to fitting the lume1 driver to the TiCu so it now matches the damascus :heart_eyes:

Outstanding mod!
Great video, love the new driver’s headstand auto dimming


I modified an Astrolux A01. It had the dreaded next memory mode (NMM), so I tried the pencil mod trick.

Here’s the flashlight and head:

I used a tweezers to removed the pill:

I wasn’t able to reach the capacitor on the driver for the pencil mod trick and eventually the negative LED wire broke off. But then I was able to write across the capacitor with a pencil and put everything back together:

Unfortunately the NMM stayed the same. So I added some more pencil to the capacitor and then surprisingly it kept the mode to only low. I then removed some of it with a toothpick, and what do you know, it worked! After all these years of dealing with NMM, the flashlight finally works like it should.

Congrats! :beer:

Modded a Sunwayman V11r to LH351D 2700k
it turned out really nice:

The beam is quite good, much better than with 219b and E21a.

Sometimes things just work out right, easily, the first time.

The larger die LH351D LED is a good match for the V11r reflector, that was originally paired with an XM-L2 from the factory.

low is 0.02 lumens, maximum is 385 lumens w 16340 at startup.

Im extremely pleased with the minimum output range, and pretty much blown away by the max output. The size and quality of the hotspot and the mostly smooth gradient blend of the spill, as well as the tint, are all excellent.

The LH351D transformed a light whose beam I was never quite satisfied with, due to a large shadow, midway out the spill, into a light I really enjoy using.

This is my first realization that the LH351d is a better match for a light whose reflector has a large opening at the bottom, than the smaller die 219b that I have used most.

I dont find the 2700k LH351D green tinted, it seems mostly golden to me. :+1:

Looks really good jon_slider! It’s great that we have so many awesome LEDs to choose from.

And thanks for the tip yesterday on the Astrolux A01 pencil trick mod. :+1:

I really like the emitter options these days. Between the SST-20, 219B/C and LH351D, there are a lot of good options to match either a reflector or optic with the emitter needed. I prefer the SST-20’s in triples, the narrow nature of the emitter produces a good end beam out of the triple. Sometimes either the 219’s or LH351D’s will work better in certain lights.

TIR optics seem to be a progression that many of us get to in the mod life of our favorite lights. And, it's cheap. I went with some single LED Carclo TIRs, ordered from LEDsupply. I have four S21As, all in 5000K, with an SST40, XP-L HI, Nichia 219C, or LH351D and I just had a bug to modify the beam of the last two. I changed the camera app setting to capture what came out closer to my eye's interpretation.

10003 Narrow Spot with 219C

10195 Frosted Medium Spot with LH351D

I bought the 10196 but haven't installed it in anything yet.

djozz found out how to max the output of the Sofirn C01. Here’s a comparison between the original Yuji ww C01 (left) and one modified accordingly using a rngwn 32K-EX (right):

Modded my Enogear/Fireflies AA Stainless Steel flashlight.
I picked the - already modded - 15mm driver with Bistro HD OTSM that I had in my Tool AA 2.0 Panda White, had to shave it a little more to fit in the brass pill of the Enogear.

I also picked the Luxeon V2 3000K I had installed in that same flashlight and put it into a 10mm DTP MCPCB I got today from LHT store in AliExpress. Well, and then I picked the pebbled TIR and also replaced the original clear TIR of this light.

I am not using the driver retaining ring because the driver is thicker than the original one and the ring doesn’t screw in.

Result: TOP! I like it, it only misses a FC switch instead of a reverse clicky! Aside from that, the DTP MCPCB will handle the heat better than the alu one! The beam is a floody warm white, which I love!

Now
I just need to make it a lanyard :wink:

I modded mine with a FET only driver but wish I had a 15mm driver with a 7135 or some other regulation cause it’s too much. Where did you find a TIR for it?

I read about your experience on the flashlight thread and figured that it would be a risky move! But with a MCPCB and a different LED I guessed it wouldn’t be so hard on the light :wink:
This driver is from Lexel and it has indeed a 7135 chip on the top of the driver.

The TIR is from this store at AliExpress: Page Not Found - Aliexpress.com

I bought some a while ago and I’ve used (and still use) them in different lights! It has the same size as the original TIR :+1:

Man I looked for this so many times. I guess I overlooked that 17mm w/ holder = 15mm without holder :person_facepalming: - thanks.

Next up find me a copper XP PCB that’s 1mm thick :slight_smile: - I think the “massdrop” AAA’s have them and some special lumintops. Wonder if they will sell separate?

And then finally a 15mm driver with some sort of regulation, Lexel MIA so I guess you have a very unique build!

Ahah, measurements when considering the holders are somehow tricky :stuck_out_tongue: I never use them, just the optics! And these fit well in other lights too (DQG Slim TI, Sofirn SF10, SF14 V1, Tool AA
) :wink:

As for the PCB, check these, the ones I ordered: 5.94€ 5% OFF|KDLITKER 3535 10 DTP Kupfer MCPCB fĂŒr Cree XP Serie/Nichia 219 Serie/3535 LEDs|Tragbare Beleuchtung Zubehör| - AliExpress
This is the Kaidomain store in AliExpress, as you’ll see for their other products :wink:

Yeah, unfortunately Lexel may not be well and did another pause here, so these drivers are not available now. I wanna order some myself, for other mods, but I am not sure when will it be possible!

Hope you can do a nice mod with you FET on driver and those MCPCBs :wink:

I have those and probably some from MTN too. I vaguely recall it created a bigger gap than I liked with the pill. Guess I just need to sand them even though I dread doing it. There was some good suggestions in the last pages on doing it however. Using a hard stainless 1mm washer with 10MM+ ID might be the quick and dirty way.

Hum, when you say the gap, you mean between the PCB edges and the borders of the pill?

This is how it looks in mine (nevermind the soldering :smiley: ) :

I won’t bother too much with that because the contact “forced” due to the pressure of the optic+gasket in the MCPCB will make it get in contact with the pill!
As for the pill in the head and tube, I have no gaps when putting it all together :wink: All fits well, no gaps or rattles :wink:

I have found during SP10S emitter swap that Sofirn mcpcb is the same size as those in Olight Warrior Mini but for 3535 emitters. And Barry doesn’t want to sell them
