You need to be aware that there is a feature in the UI that gives you the ability to jump to high if you click within 3 seconds of turn on.

Oh ok I think I get it now. Thanks. Though mine is just within a second. The timing seems to leave little room for error on mine. I guess I’ll just use L-H cycle to avoid frustrations.

Today I modded all my 3 Headlamps.

with 2 Anduril Drivers from Quadrupel and one Attiny 412 from gchart. The second Attiny got a broken leg after some problems with a short causing the LED was always on.
But finaly all 3 Headlamps has ramping with Ramping iOS or Anduril.

I had two Drivers with Ver03 and one with Ver01, so the Ver03 got the Attiny 412.

Thanks to you both.

I changed the LEDs too:
2x LH351d 2700K + 5000K 90CRI
2x XM-L2 NW (3B or similar)
1x SST40 5000K

Drivers and Flashlights from recent posts for reference:

Sorry to ask this question again…. but I plan on getting one. Has anyone officially determined if these XM-L2 LED’s are not a real cree? I played with a wowtac a2s then a sofirn sp40 and I was thinking of getting one of those for myself. I then ran into the D25 and thought it would be within 1-2% difference between them, since they all have XM-L2’s. I would actually expect the D25 is better because it has 2 XM-L2’s? I’m not sure I understand.

They has XP-Footprint and I think they are no genuine Cree LEDs.
They looks similar to XP-L LEDs.

Strange. It must vary from source to source. Mine had the 5050 (XM-L2) footprint:

You are right, I checkt my lights.
The older one, with the driver-pics in this thread has XP-LEDs. This is from Xanes, ordered from Banggood.
The newer from Aliexpress has XM-L2 – Style LEDs, with “LMP” written on the LED.

Its a pity.
Yesterday I wanted to solder the Attiny from gchart. But I have Rev1 and it didn’t work.
Once I connect the battery it switches on at low level. After (not while) I pressed the switch it dimms down to lowes mode. And there is no way to make it brighter or switch it off.



Some Quotes for reference:

Uh oh. Glad you pointed this out, Jason. Glad I haven’t sent out too many MCU’s… they’ll need to check which version of the driver they have.

Here’s mine (D25) with the MCU removed. It appears to be the same layout as Tom_E’s

Wow, this is a good thread. I wish I had found it earlier.

Someone said earlier that the D25 and D10 had the same driver.

Here is Tom E’s stock D25 driver. – - – - – - Here is Flail’s stock D10 driver.

Note the dot on the chip.

The pcb layout looks the same. Maybe these are different chips and the dot has a different meaning for each chip? I really don’t know.

The pin on the upper right in the driver pics looks like it goes to Batt Neg on both drivers.

@ gchart. No pics at the moment, but 2 of mine are ver:05. Any idea if your mcu swap will work on those?

Side note. Where in central Illinois? I thought I was the only non-Sh#*cago Illinois resident here.

Are there any TIR optics that are simple drop-ins for either the D25/D10? Browsed quickly through this thread and it looks like the ones that people recommend still need some shaving down to fit.

Sorry for the late reply. I’m in a town on the outskirts of Peoria. I feel the same way about that other city.

I don’t know for sure about version 5. Mine were 3. But the MCUs are inexpensive enough that it wouldn’t cost much to try if you’re interested.
