Is this convoy S6 host?
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
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
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
Party has started
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:
