ENEDED

I’m guessing it’s a poor photoshop job. The S41s has a crooked head/body as well. :slight_smile:

I’m not lucky with s41s. Ordered 2 times, got problems both times.
First time, ordered S41a head. Arrived 4 days ago. Led’s dome damaged eventhough I haven’t unscrew it’s head(may accidentally unscrew the bezel when I unscrew the head but I’ts just 1/4 turn at most). I can noticed it only in moonlight mode. 4 leds still work fine. This may reduce it’s efficient a little but still work fine in real life. I contacted banggood for compensation and still waiting for result.


From the picture, it’s in moonlight mode.

Second order, I ordered SS body tube and SS tail cap(they’re out of stock when I order the head). Got them today. Tail cap is fine but body tube has strange color. Don’t know why, may be because they forgetting something or do coating before machining or whatever. I ordered it because of it’s looks, though. I contacted them and waiting for reply.


Sorry for low quality pics. My cheap cellphone’s camera just died and these pics were taken by a cheaper one. lol

TIR can be easily replaced. PM me if you need help for your order.

Thanks. I contacted banggood and they gave me a refund. It’s not worth much but better than nothing. w

Apologies if this is not the right thread for this, but I have a question about how to configure the S41S.

Just got a S41S from banggood and I can’t seem to change the mode grouping or toggle memory mode. I turn it on, click 15 times, wait for the 2 blinks then turn it off after the two blinks to toggle that specific option. Is that the correct procedure to set the configuration? Is there some trick to it? I’ve tried this 4 or 5 times now and can’t change the mode grouping or toggle memory mode. Light seem stuck in group 1 with memory mode off.

Edit: Looks like it was my error. I needed to turn off between the two blinks not after than.

Does the S41 have Bistro or A6 UI?

A6 firmware for S41/ S41S, according to their product descriptions.

+1

I have the S41s and I can confirm that it has A6 firmware

I’ve occasionally heard that the later batches of S41 may have had bistro, but I’m not sure. Originally it was going to use bistro, but the drivers were too sensitive to voltage spikes and couldn’t handle the amps of a multi-emitter light. So they used the older blf-a6 drivers instead, which are more tolerant.

The voltage-spike thing has been fixed in later BLF drivers, but last I heard, it was still a problem on banggood’s bistro drivers.

I can confirm that my S41 which i received a week or two weeks ago and it uses the same firmware as the BLF A6 firmware.

Thought I read this somewhere too, but wasn’t sure if I had it confused with another light.

Thanks! I was wondering why it would have A6 since this came out after the X6 II, but that explains it.

Ordered one of these:

It was delivered today, but the embroidered name is not Astrolux, it’s MATEMINCO.
Makes it kinda obvious who is producing Astrolux for BangGood.

And MATEMINCO still is…

Hello toykeeper, thanks for pointing that out :wink: do you know what kind of problems do that caused? I mean, is it some obvious malfunction or is it more about working regularly for a while and then risking to fail later?

What happens is that the driver reboots. When the FET opens it lets current through, then when it closes it causes kind of a shockwave strong enough to reboot the MCU. So, in the strobe mode, for example, it’ll flash once or twice and then go directly to moon. Or it can go from turbo to moon, or one of the higher FET modes to moon, on its own.

Basically, if it runs at full power it reboots itself and goes to moon.

The attiny13a is tolerant enough to keep running regardless, even when it’s getting far more voltage than it’s spec’d for. But the attiny25v doesn’t respond well to these voltage spikes, and it reboots.

Newer driver designs eliminated the voltage spikes, but I don’t think banggood has any of those newer designs.

I got one of those too. Ordered 2 of the holsters, one had astrolux, the other has mateminco on it.

I see, that’s good to know, thanks a lot for the explanation and for your awesome work! :wink:

Any chance we could get new deal for Astrolux S41S SS ?

This is the one I know: Banggood : Global Leading Online Shop for Gadgets and Fashion

Thanks g_sintornillos ,
anything I should be aware before ordering? I see that many people were not satisfied with QC, mostly damaged emitters, leds with different tint etc!
I wanted to go for Nichia version.
