Gotcha. I don’t like the beam pattern of the s42 optics with xp-l hi and maybe this is the solution. I think using the stock mcpcb as a spacer might work. Have to sand it down to expose the copper obviously.
After several hours my first real Mini C8 mod is finished. :)
The JAXMAN M8 (formerly known as Mini C8) is one of my absolute favourite light still today.
A long time ago I got some of these cheap LED bulbs at the german Aldi Süd (12 V GU5.3 with 38 ° beam angle).
This mod features this large coin spacer with 62 grams weight. :)
Some days ago I noticed that the lens of it fits perfectly in the M8 head and I got the idea of a Nichia triple for floody high CRI light.
It looks small even in comparison with a Thrunite TiS / Ti3:
The beam pattern is beautiful, with flood everywhere.
The saturation is incredibly high, even higher than of the Lumileds Luxeon MZ 5700 K 90CRI I tested recently. In direct comparison the tint of the used Nichia 219BT-V1 R9050 sw57 is a bit rosy and more on the blue side, but not too much. The XP-G3 shown here is definitly warmer than the stated 5700 K (and a lot greener!) despite it was ordered at Mouser:
The M8 is powered by a good old 105c, with custom firmware (3 modes + 1 moonlight), with 2,800 mAmps current. I didn't want a dragster, but a useful and durable light for everyday use and I have the option for increase the current sometime. But I'm satisfied with that, and on highest mode (no stepdown) the battery lasts for more than one hour.
Can anyone help me out, I have one of the astrolux/Blf 17mm “Lighted’ tail switches. today I decided to change the colour of the LEDs. so i desoldered the current two and replaced them with some smaller 0805s, but, only one will light up? i have changed the polarity of the other one and even changed the LED a few times but still no light to the second LED. do i need to change the resistor values or something?
Modded a Klarus Mi7 14500 flashlight with a BLF X6 driver modded with a attiny85 and a east92 board modded with NarsilMQ8 firmware.
That’s a lot of modding.
I’m afraid that requires troubleshooting yourself where the bad connection is. Did you pre-tin the leds?
Apart from a bad connection, if the two leds are a different colour (especially if one is red and the other not (green, blue etc.), the voltage difference is too big and only the red one sucks all the current and lights up.
Another way to solve it is finding a way to solder a separate resistor for each led, then a red and other colour led is no problem. I did that once for this board: currently they are behind a common resistor, but if you cut the long trace that goes under the switch and add a extra resistor for the now ‘cut-off’ led between led and switch-pad (sorry, no picture but I guess you can think it out), both leds will work. The two resistors must have twice the value then, to have about the same combined resistance as before. Or you can tweak the values to have the two leds light up evenly.
Great work on the bezel, I had been planning on doing the exact same thing, nice to see someone has done it and what it will look like.
I’ll bet it took a while even with that small amount of stainless to sand off, did you start with coarse and go work up to fine, or just use one grit the whole way through?
Woo-hoo, finally unlocked the hidden beauty inside the Astrolux S42. Using one of Lexels’ S42 Narsil drivers, the S42 now has access to moonlight, turbo, last-mode-memory and stepless ramping etc.!
And since I didn’t mind a little parasitic drain (certainly much lower than the OEM dragon mode drain), I managed to keep (a red) locate me mode (as it doesn’t “breath” like original).
Not today, but on the last weeks, I modded some lights (yeah, the pieces finally arrived )!
Simple mods, but still some troubles :person_facepalming:

I’d wait, from what I understand they’re updating the driver in the next version. I don’t know if it’s Narsil but in any event it’ll be an improvement over the original UI.
If you don’t want to wait, you may want to get the copper head. It gets warm faster now .
My first Maglite mod will be soon made. I got a 2D led pro from a hungarian forum member as a present because I have never touched any Maglite So I decided to give it some power.
Exploded:
My plans:
Making a spacer for 4 convoy S2+ reflectors it will have 39mm material under the leds
Design done:
Sand down the paint on top edge of tube because that will be contact negative to spacer and then driver.
The driver will be a Texas Avenger LDO 2S 21mm driver with E-switch and Andúril firmware in the bottom of spacer.
I will cut the top of the switch holder to put in a copper contact plate and I will use 2x 18 AWG wire to contact it with battery positive contact terminal through the gutted switch.
I will put in 2x26650s and spring bypass on bottom end, and they will be driven 4 pcs SST40 Leds in 2S2P led config. I hope it reach 8-9000 lumens.
And maybe I turn some heat fins on the head for better heat dissipation.
Most of this are plans but I have the leds and driver parts so soon will be made.
