There is also an image showing the laser engraving:

If you want to go professional, there isn’t much choice. Either The Sofirn/BLF LT1 or the smaller Sofirn LT1S Pro. Both have the Anduril operating system with a very complex, but also very powerful UI, they have adjustable color temperature and brightness – both either stepped or smooth – and the LT1S Pro even has a red channel!

Can this actually do a sustained 800lm for 6 hours per the manufacturer spec?

I don’t think so. If you ignore the stepdowns in my runtime measurement and assume that it can maintain high level all the time, I’d say the total runtime at 800 lm will be more like 3 hours. Which is more or less what you get from the flood channel after the initial stepdown. Turn it on at turbo, wait 30 seconds for the stepdown and then you’ll get almost 3 hours at roughly 750 lm.

Wann geht es denn hier weiter? Durch die Deföderation ist ein großer Teil meines Netzwerks weggebrochen, sodass ich mir dort jetzt einen weiteren Account angelegt habe. Das kann eigentlich nicht der Sinn eines dezentralen Netzwerks sein. Klar, ich könnte mir eine eigene Instanz aufsetzen, auf die nur ich Zugriff habe, aber das erscheint mir etwas übertrieben. Lemmy bräuchte für so einen Fall eine Single-User Version. Vielleicht gibt es sogar schon irgendein System mit ActivityPub, das so funktioniert… Mal schauen.

Awesome! I think c/flashlight is a really great alternative to r/flashlight, especially if more people would post here.

And thanks for the giveaway!

Yes, you could (theoretically) use an emulator for the microcontroller. I tried it a few times. And it isn’t fun. It takes a lot of effort to simulate all inputs, outputs are hard to interpret and all kind of effects of the real light aren’t reproduced.

In reality we flash the build onto a flashlight and try it. Sometimes it’s only a prototype, disassembled. And rarely it’s an actual devboard which has all relevant parts of the flashlight nicely accessible (basically the microcontroller with required electronics, regulated power supply, low power LED to see the output, several LEDs for aux and button and the switch itself).

The UI of the Manker E02 II is very similar to the Skilhunt UI. Low group with 6 (?) levels of very low light, medium level and turbo. Not sure how it could be much shorter. Same for the ZebraLight, it can’t be any shorter to fit a AA (except for the H50 which doesn’t have a reflector).

I noticed this usability issue of lemmy as well. The photo is the one you can set as the URL for the post and a thumbnail of it should be shown at the top. Here’s an embedded version of it:

In Germany we have them everywhere. When I look out the window I see at least 10 of them.

When I count up to 100 I’d be able to count much further. In practice I’d just use my phone or a dedicated GPS receiver.

They are recalling the H150 and will exchange them for a fixed version. It’s a huge financial loss, though. And I don’t want to be the engineer who caused this trouble.

Probably yes, if you were able to unscrew the head (they use very good glue). Also there are several other components at the battery side of the driver. Lastly there’s always the chance other components fall off from the heat, maybe at the back side.

So yes, it’s possible, but difficult. The good thing: You don’t have to worry about it, Skilhunt is recalling the H150 and will exchange them for a fixed version!

Practicality depends on your preference. It’s heavy, some people say it stinks. But scratches don’t make it look ugly and it ages nicely with time.

I guess tailcap current measurements with a DMM are good enough for my purposes.

Only as long as you use a clamp meter.

Reading a voltage would be possible (but the ADC code is already very complex and messy). Some types of drivers have a sense resistor already, but usually it is connected to an opamp and adding another load might cause visible fluctuations in the output.

So yes, it could be possible, but requires a driver redesign and lots of refactoring of Anduril.

It looks like a rebranded Yinding or Rayten LED that is already used for a while in other flashlights. It’s definitely not their own development or production.

As already mentioned, this is the post-off voltage display. Depending on your firmware version, its time can be changed from the battcheck menu. Set to 0 to turn it off.

The red flash is a bug that already got fixed (together with several other bugs). Do you have a flashing kit for updating the firmware?

I don’t have one, but I’m pretty sure it has a different driver. Never seen a Chinese flashlight engineer using an AVR microcontroller for their work.

My review includes a photo of the disassembled head. It’s an easy reflow.

The IF22A has a completely different driver.
