Yeah, same here. I still have 2 more coming my way which I ordered before knowing about the NMM. I’m hoping that someone comes up with a fix for it as I don’t have the expertise to do so.

Some NMM drivers in the past could be fixed to no memory with a pencil stripe over a capacitor. Who knows.

I change the xm-l2 in ec4 to xhp50.2
But, too bad, it doesnt work properly, sometime it can go high mode, or doesnt work, or very low output

With 2 cell and constant current drivr, i hope it works, but disappointed, now i have to order xm-l2 led

XHP50.2 is a 6/12V LED
XM-L2 is a 3V LED

the old XML2 should be fine

I know, but i measure the Voltage when open circuit, it’s almost same as Vcc(about 7. Volt), so i guess it will adjust the volt so that current is stable

I have EC4 with XHP70 and stock driver and it works well. You need to use thermal resistor.

I lost the thermal res when reflow the led(damm, that little thing), i dont know the value, so i just solder 10k resistor

So, i reflow the xpl-hi led, change mcpcb to cooper, now it works, so i guess my driver wont work with xhp50 led
I’m sad:(

This is bad news, I want to swap to XHP50.2 too in my EC4…

I dont know will it work, because kiriba said that he modded ec4 with xhp70, and it works, so… i dont know
Maybe difference in Vf

This is maybe my last pic of xhp50.2, before i lost it in my drawer
God, i always love seeing led under UV light

Yes, I got the driver from Kaidomain. Whenever you turn on the light, it’ll go to the next mode that you last turned off the light on. The driver has ll-l-m-h and then double click for strobe. So if you turned off the light on medium, it’ll start on high when you turn the light back on.

I have the same driver in a Eagle Eye X7 with a XHP50.2, even if it’s on time memory it will start on the same mode if the flashlight is turned on for more than 3 seconds, less than that and it will go to the next mode. Does your driver also have a pre-flash in the low mode ?

Yes, there is a pre-flash on the lowest mode.

Quick Mod on 1508 75mm:

- XHP35HI on16mm copper from Kaidomain
- 1 Mode Buck Driver from DX: http://www.dx.com/de/p/18v-5w-cree-circuit-board-for-flashlights-16-8mm-...
- Modded with R100 instead of R200 for 2,5A, like wrote on http://www.videofoundry.co.nz/ianman/laboratory/research/driverlist.php (search for “TR-0021b”)
- At tailcap 2,33A
- with 4× 18350er Batteries
- Driver heat with https://www.fasttech.com/products/1…al-conduction-silicone-rubber-cube... to the pill

At 5m I have measured 372kcd, thats aproximately 1220m distance.

Propably next steps:
- soldering MCPCB to the pill
- using thicker wires and bridging springs.

I repaired a S2 triple’s LEDs (purchased a prepopulated noctigon and one LED was dim from the getgo).
Replaced them with Nichia 219b-V1 5000k emitters and a BLF a6 driver. Pulling close to 12 amps from an LG D1 at 4.33V. Beautiful smooth beam.

Voltage Meters

I added a removable voltage meter to the magnetic TP4056 Charger unit and potted the components side

.

Also some refinements to the charger tin

.

And a voltage meter on one of my battery drill packs

Just finished a Night Piercer mod of an Astrolux SC for a customer. LED swap, driver reprogram, bypassed springs, refocused reflector, upgraded wires, potted driver. Had to re-machine the LED shelf since it was bulged pretty badly in the middle but she’s nice and flat now. Came out at a cool 83Kcd (~575m).

You should post more details of that Eye of Sekhmet light if you haven’t already?
Looks really nice, interesting.

I would like to know what led you used … Not the first time i ask , but it seems i may have to ask more times Blushing

Prolly the Super XP-E2 U5 high performance 3 amper de-domed! Been waiting for the smooth reflectors to finish the Jaxman M2!!! Angry Just a wild guess!

I don’t have any to test … Edit : And they are only available at mtn or mouser Facepalm

Anyone tried them @ 3 amps & dedomed ?

I did my 2nd driver swap today, but it was my first in a pill. I put the 17DD MTN driver in my S2+ and it was an experience to say the least… I also did a spring bypass for all my tailcaps since I had the soldering iron warmed up.

I got the stock driver out using a lighter which wasn’t very fun… I got the new one in using my friend’s heat gun and that was much smoother sailing.
Once I got it all in and snug with my 25 degree TIR optic I gave it a test and all seemed well. I then set it to have 6 mode groups + moonlight for 7 modes total. I tested the turbo mode and was comparing to my triple direct drive Jaxman E2L with XP-G2s and it started doing some weird stuff… it wasn’t really hot yet and it shut off straight to moonlight mode. When I did a half-press to enter the next mode it turned off completely for a few seconds then did a bright burst of light and started flickering… I unscrewed the tailcap and put it back on and every mode worked fine no flickering, but once turbo was on for several seconds it shut down to moonlight and did the same nonsense… I took the pill out and every solder connection was sound so I put the pill in with less force and everything tested perfectly. The Bistro temp sensor steps it down around 1min 40sec and no problems since and tested with a few batteries… was definitely scary I thought I got the pill too hot and the driver chips floated around on me.

I’m more than happy with my S2+, but now I’m disappointed in my DD triple XP-G2 because it really doesn’t seem brighter than my BLF A6 or DD S2+… I think a DD 219C triple is my next endeavor.

Actually not flashlight mod, but I gues it is related.

Just received MAX44009 ambient light sensor from Aliexpress (https://ru.aliexpress.com/item/GY-49-MAX44009-Ambient-Light-Sensor-Modul...)
Added it to my arduino (actually STM32f103 board) with display.
So far it cost me ~ 10-12 USD (3$ for sensor 3-4$ for display 2-3$ stm32 board, ~2$ usb to serial adapter, plus wires etc.), and some time.
All needed can be found on Aliexpress (or Ebay maybe).

Roughly checked measurement results with my cheap luxmeter – results are very close, however I think max44009 is more precise.

When I’ll have more time , I would share more info (if somebody need it) Smile

Nice project!, and more info, yes please! Did the ambient light sensor come with a wavelength sensitivity curve comparing it with the official photopic luminosity curve?

Well you can see all needed information in datasheet Smile

https://datasheets.maximintegrated.com/en/ds/MAX44009.pdf

(As I am not specialist in light metering , it is enough for me to see phrases like “The IC is designed to detect brightness in the same way
as human eyes do” in datasheet Smile )

And I gues minimum parts needed :
- to get (i assume precise) data from this device it is enough to have devise itself, standard Arduino Uno board (it should be powered from 3.3V – I am not sure all boards can work with this voltage) and USB port on PC – to get data from.
- And software part – Arduino SW

Thanks for the datasheet (and sorry for not finding it myself). Here’s the spectral response:

That is not bad for an ALS actually (most ambient light sensors have a spectral response that is rubbish) but it is worse than a good luxmeter. The main error is that the blue peak of a led spectrum will be overvalued by 100%, meaning that cool white led light will be measured too high compared to warmer light (think 10% or so).

The best ALS I have seen sofar is the Texas Instruments OPT3001, if that spectral response curve is really that close to the CIE1931 luminosity curve (which should be the red line) it would make a better luxmeter than anything under 300 dollar:

well) i dont see principal difference in obtaining data from OPT3001 ) so, i will order one module to try as well)
