Fixing my friend’s C8 and the LED was peeled off. Need a quick setup to reflow new LED into base plate and here is my setup

I forgot taking picture during the process so I took this pic after everything was done.

Took a minute or so before the tin is melted.

Steel_1024 those pictures are so sharp! The driver looks almost unreal, CGI-like. That optic is about the clearest and cleanest I have seen, even with my own eyes.

Lumenzilla now that’s something new, reflow by flame Big Smile

Hello mate's!

 

A few week's ago I has finished my first modification.

It's Sipik SK68 clone, that I change:

  • LED: XM-L2 2800K
  • DRIVER: NanJG 105D
  • SOFTWARE: My own with big help from DEL (member of this forum)
  • CONTROL: Microswitch

 

Features:

  • Soft transitions between modes
  • Soft start and soft off
  • Battery inductor
  • Turbo mode
  • Beacon mode

 

Here is a video:

 

I planning to create an article in this forum about this modification,

so more details very soon.

 

Best regards from Poland!

Since I don’t have a workbench at the moment, mods have been placed on hold. I did get to spend some time last night rebuilding my brother-in-law’s UniqueFire HS-802 though… His was an original I had purchased for him, back when it was a current-model light. I have a newer one I had purchased for myself that I have previously modded with a 2.2A Qlite and a XP-E2 Torch emitter with fantastic results.

Unfortunately, in the case of my brother-in-law’s light, the process didn’t go so well. I was finally able to brute-force break the glue on the battery tube using a crescent wrench and heavy strap-wrench to remove the head making repairs/mods easier. I’m not sure if the reflector design has changed, or if due to something else, but I wasn’t able to get the XP-E2 emitter to focus correctly. I tried repeatedly with different centering rings, spacers, and insulators, but was never able to get a proper hotspot. Ultimately, I ended up simply removing the original EZ-1000 XR-E and replacing with one of my spare EZ-900 XR-E emitters, and swapping the original 1A driver with a 1400mA Nanjg 101 AK. Kind of disappointing, but at least it is brighter than the original configuration.

CRX, I am interested in this process. Do you have a write up about it somewhere?

Edit: never mind, I should have kept reading.

What you guys think is the maximum wattage to be dissipated on a 105C/D style stacked driver (not potted)? I’m currently building a triple 219C R9050 EE X6, have 16 AMC7135 installed on a 105D driver (running BLF-A6). With the low forward voltage of these 219C’s I have a feeling that’s a bit much power to dissipate at the driver, about 5.8 W in the worst case (fully charged high drain 18650).

Well with a FET the excess voltage gets burned in the LEDs, right? Maybe the driver will stay a lot cooler, but the 219C’s will run nuclear in no time.

That is some flashlight capital you have there Mitko, what is the mod? I notice that one reflector has a different finish Glasses

@chouster: you can get the driver dissipate the heat of those 12 chips if you have a plan where it goes. What I do is for each stack connect the large lips of the chips facing the outside of the driver with a generous amount of solder (solder is a pretty good heat conductor!), and let that blob end right where the driver’s ground ring is clamped to the pill/body/retaining ring.

And I think that I remember that 7135 chips have an internal heat management and drop their current if they get too hot. Anybody confirm this?

M22 will be dedomed /w fet driver, the result is like 1700lumens and 90k cds, its some kind of a luxury X6 of some sort, the beam profile is virtualy the same yet the heat disipation/the host is ways better

M2X will be modded the same way, the result is 250k cds

M3X i apply only a modest driver mod( 5.5 amps at the emitter) and i pot/ heatsink the driver, its kind of a fragile one( from experience), several ot those M3X will be XPG2 moded ofc

The solder connections on the big ground tabs is what I did. I’ve read that about the AMC7135, someone confirmed this by testing but I can’t remember who it was. Problem with that is, there are many sources for those AMC7135 chips and we don’t know if every chip acts that way.

I’ve not had this problem with this driver, but most of my experience is with the mtnelec version of this driver. Is it only present on the “chinese” driver that comes in the X5/X6 lights? Or is mtnelec’s version also susceptible and I’m just lucky so far?

I am having the same problem in a triple 219C with the genuine Mountain driver. Will have to try this when I get time.

What did you use for a spacer?


I roughly cut two discs from a 3mm copper plate that I have. I then solder them together and drill a hole in the middle.

You modified the Blf-A6, a FET+1 firmware?
I’m running a S2+ with 3× 219C and FET+1 (modified Blf-X6-driver) as EDC, of course it gets hot fast in turbo, but with a “not-too-high”-drain cell like Sanyo 18650GA its really usable.

I noticed this behaviour with a 105D.
