I recently ordered quite a bit on mountain electronics so I am good for a while. But if I ever order again there, I will let you know.

Looking forward to it, Thanks!

Finished modding my broken Zebralight SC52w into a triple.

It now features:

  • Anduril driver
  • Carclo 10507 optic
  • Triple 4000K SST-20 95 CRI FD2 bin emitters.
  • Spring bypass in tail.

I quite like it. It’s not much bigger than than an FWAA, but has a great clip, excellent button, and is much throwier due to the larger optic.

Nice save!

Jetbeam TCR-1 mod to 219b 3000k

.

started by reflowing a triple mcpcb
.

after reflowing the LEDs I realized the MCPCB is too big.. will need grinding

meanwhile decided to install a single 219b 3000k
.

Very happy with the warm 3000k.. for camping and full dark use, I personally I like 3000k better than 3500k.

Is there a sense resistor on those new drivers to bump the 7.5 up to say 9 with the sft40?

On the K9.3 driver the sense resistor is 10mΩ and and the sense voltage is bumped to 90mV compared to 50mV in the 5A KR4/D4V2.5 driver (also with 10mΩ Rsense). I assume it’s the same for the 7.5A driver, no change to Rsense and Vsense = 75mV.

Either can be changed to get the desired current.

Curious as to what numbers you’ll get from the KR1 and the D1S!

Couple simple aesthetic mods to my Zebralight SC52w triple.

  • replaced stock clip with titanium deep-carry clip
  • added a few strips of Talon Grip Tape.

Not sure if I’ll keep it like this or go back to the stock clip and no grip tape.

Here are some pics next to an FWAA:

I am not sure, i will have to look at it, maybe someone can share a picture of what that should look like?

 

I know, i ordered these 6 weeks ago. Had i realized i was using a sft40 i would've asked for one of them to be 9amp. but then again, heat is a factor, so 7.5a might not be terrible in that small host.

hmm. this sounds interesting. would you be able to share with me what part would be needed, and where it should be soldered, to make this change? I have a feeling i get the concept of what needs to be done, because -

 

I feel like there is an old Matt Smith (Adventure Sport) youtube video where he mods a driver of some sort by soldering / stacking resistors onto each other to get more current? I wonder if this is the type of mod you and JaredM are referring to?

CNCman - haha! yes it is, im pretty excited. Will probably take me both days due to small obligations around the house. lol

 

TmaxxJJ - I know me too! I know the FET enabled KR4 driver shold pump out some amps with the Molicel P26a i will use in that KR1, I'm excited for that! 

 

And the D1s should be good, once i can properly tune that beam! its been rough, and i've got over an hour just into reaming the reflector and swapping between different centering rings, no rings, kapton tape, etc.. If i cannot dial in the beam very well, i may try the CULPM1 in the D1s as well... but i really do not want to "throw in the towel", but that D1s reflector is being a motherf**&er to try and dial in with that SFT40.. It started out horrible, so at least I'm making progress lol..

D1s from what I remember hearing had a flawed reflector. I believe the GT mini reflector fits it however.. but maybe I have that backwards.

About the sense resistor, you’ll see a relatively large resistor marked with R010 or something similar. That would mean its .010 ohms or 10 milliohms. Whatever the value is, the formula is as follows.

Sense resistance (milliohms) * current (amps) = sense voltage (millivolts)

For example

10mOhm * 7.5A = 75mV

You then use this voltage and work backwards using your desired current. Lets say you want 9 amps

75mV / 9A = 8.33mOhm

So thats your target resistance

Resistors in parallel behave such that the total is the inverse sum of the reciprocals.

So 1/0.00833 = 1/.01 + 1/x

1/x = 20.05

X = .050

So stacking an R050 on top of a R010 should yield 9A.

And to modify Vsense you can change R3 :

R3 = R4 x (VCC-Vsense) / Vsense
With VCC = 2.8V and R4 = 3.3k

For 50mV you get 181.5k (180k is used), for 75mV 119.9k (probably 120k is used, check the code on the resistor), for 90mV 99.4k (100k is used).

Flawed reflector, or just tuned perfectly for a XPL-HI? IIRC nothing with that LED throws as well in its size class.

Artie – Have you got yourself a light meter yet so you can measure some numbers? Also for the tuning, or are you doing that by eye?

As I said, I may have had that backwards. D1 definitely had a bad beam, and I remember some folks swapping reflectors between D1s and GT mini. I can’t remember which was better and never had either personally.

Got a cheap triple flashlight from Alonefire. It comes with a white, warm, and UV LED. Swapped out the random white and warm LEDs with a XPL-HI 5000k and a sliced LH351D 2700k. Apologies since I can’t really manipulate white balance properly. The LH351D looks more orange IRL rather than rosy.

Sunwayman V11r
LH351D 2700k sliced dome
.

low 0.02 lumens
Turbo 335 lumens

repacked control ring w Nyogel 767a
.

.

unfortunately the beam is unacceptable due to a dark shadow in the spill (this does not happen with dome on)

===
redid the reflow to an LH351d 2700k with stock dome on
.

low 0.03 lumens
Turbo 425 lumens

the beam is Much better!:

So far, i got the xhp35 HI 4000k in the M2r warrior, and i got the D1s done! 3.5 hours later! heres some pics. sorry for the link, dont have time to upload pics, but wanted to share!

Highlights: 

Emisar D1s

7.5amp KR4 driver, Anduril 1 

Lighted Cyan Switch

SFT40 LED (still needs to be tuned properly, height adjustments)

Artie, where did you get the side switch, I need one for a MT07.
And could you explain what beam appearance you are looking for when tuning ?
Got several lights that need tuning, never knew how.
.
Nice mods Thumbs Up
I did not know the SFT 40 could handle 7.5 amps, wow Shocked You are giving me ideas Wink
