Flashlight Modding and DIY Parts

I’ve never had a Zebralight, so I won’t even begin to compare that. And while I don’t have a KR4, I do like Hank’s lights. Crazy thing though… the Noctigon KR4 and the Amutorch E3 are almost exactly the same size, but the E3 is 21700 whereas the KR4 is 18650. E3 dimensions: 95 (length) x 29 (head) x 25.4 (body). The KR4 is 98 x 29 x 24.

The difficulties / setbacks:

  • The driver was designed specifically for this light and had to be fairly exact in its dimensions so that the screw holes and the switch lined up properly
  • The driver cavity is very tight, no room for any extra wire or anything
  • The E3 is a unibody, so everything had to be fed in through the tailcap
  • The hole for the LED wires had only so much room, so I used 22ga primary wires and some very very thin 30ga Kynar wires for the aux
  • When I first got it assembled, only the blue LED of the RGB aux worked
  • With the ramp config on default settings, the LEDs wouldn’t turn on at the dimmest Anduril setting
  • Shortly after assembly, the 7135 got stuck on all the time. Must have been defective or something. It was an extra crappy “crappy sailboat” version. Lesson learned.
  • So… I took everything apart
  • I updated Anduril2 for the AVR 1-Series to use phase-correct (dual slope) PWM with a 10 MHz clock instead of single-slope PWM at 5 MHz. This fixed the lowest ramp setting issue.
  • I also replaced the “crappy sailboat” 7135 for a “raptor claw” 7135 that I removed from another driver.
  • I then bench tested everything to make sure it worked before reassembly
  • I then reassembled everything yet again, being extra cautious every step of the way, especially with those aux LED wires
  • It worked!

This makes me feel better that you go through some of the same frustrations I do on mods.

And yes one thing I’ve learned for certain with 7135s, the good ones are good and the bad ones are bad.

Not to take away from all these other great mods here lately. You guys are AWESOME !! :+1:
Blazing new trails and ideas. Ol Lumens would have serious competition these days. :sunglasses:

Great build gchart. :slight_smile:
I’m not a fan of how bulky are the latest Hank’s 18650 lights either.

9920

Today I adapted the GT4 handle for the Nano :nerd_face:

(am bored today)

5€ red flashlight with red osram :heart_eyes:

Almost perfect! I’d like to see a shoulder strap though :smiley:

9923

I guess it’s more comfortable now? :slight_smile:

minimum 0.03 lumens
maximum 300 lumens

Good one !

I modded the state of charge of the Sony VCT6 in my FW3A today by removing the cell and placing it in my Liitokala charger.

9926

Another nice 219B sw45k mod jon_slider! That is an amazing LED.

9927

thank you very much for the kind and supportive words. You have very good taste…

fwiw, that Nitecore EX11.2 has an sw45k from Bob McBob. It is the most pink variant, a D200, highly recommended.

andy zhu also has sw45k, they are D220 and are nice too, less intensely pink.

in the past andy also had sw45, non k, and less pink of the three, but still has a slight pink tint, noticeable when compared to CW and Low CRI Leds whose DUV (Tint), is farther above the BBL

andy has a great variety of other 219b LEDs too…
I like the sw30 he has too, recommended.

9928

I have the 219B sw30 D180 and sw35 D200 LEDs from azhu. They are very nice!

And I also got my sw45k D200 from Bob McBob. Agreed, highly recommended.

Have you tried the sw40 D200 from Illumn I have them in a quad Convoy M2 and I think it’s probably my favorite CCT/tint of all my flashlights. :heart_eyes:

9929

congrats on finding love :wink:

I had not tried the D200 sw40, I have a D220 sw40 and I wish is was more pink… Thanks for the tip! :+1:

I do have sw35 D200 from azhu, but it is not a favorite… “too green”… lol

9930

If you want a nice rosy 3500K, try the Nichia E17A SM353 from Eurekatronix (Virence).

Here’s the sw35 D200 on the left vs the quad SM353 on the right:

9931

thank you for the comparison photo,
that E17a 3500k looks very nice,

I had not seen it before
and the tint looks nice for my pink preferences

what light is that in… curious about the optic

9932

They’re in a pink S2+ host with a frosted lens. Here are some pics:

9933

great photos
looks very nice…

is there an Anduril driver option? :wink:

9934

I’m just using a Convoy driver. The safe max current for these quad E17A LEDs is 4 amps.

9935

Nice mod NeutralFan! And always clean :heart_eyes:

Hum, to help answering jon_slider’s question about Anduril driver, would I be wrong saying that: to use a driver with that firmware in a Convoy S2+, it would need some major mods (inner tubes, eventual pill adapting, different switch, ….) to make it work, and that to use this kind of driver (FET) with those leds, it would need some “throttling” to maintain the max current on/under 4A?

Thanks for showing again :+1:
