What did you mod today?

Yes, the picture is a link to thread.

Got this freebie

And invested more Free parts… Making this

Switch has 3 modes to light up 2 bulbs, 3 bulbs or all 5.

I did my first ever mod and it was a spring bypass on my beloved M1

Modded a Supfire M6 today.

fet+1 with narsil (loving the firmware)
XP-L V5 4500k
hand filed aluminum spacers

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).

This is not good :wink:
put on board so many of AMC.
better to put a quality FET for DD

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.

Some M22 moddings

wow you have so many M22

Im yet to own one :frowning:

Well, it will be the Olight modding month dude( at least for me)

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

@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

Yeah thats the result of a EU Black friday :wink:

Party has started :smiley:

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 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?

Astrolux SC quad :

Spacer from kiriba-ru , Carclo 10622 optic , Nichia 219C 4000K CRI 90+ D240 leds and old dsche copper quad mcpcb .

Stock driver , with bypassed spring . Also added the second LED & Resistor in the tailcap PCB . Leds on mcpcb is soldered on the spacer and spacer inside the head too .

Unfortunately i don’t took pictures during the mod , i had my phone for repair .

But here are the results :

Pulls 12 Amps from the little Efest 14500 V2 650mAh :heart_eyes:

Edit 4/24 : Pictures fixed

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 3x 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.
