Ok. Great. That’s what I’ll do. I love this little light. It’s a perfect put in your pocket everyday and tell friends, look how bright this light is for its size. Will this affect any dust ingress?
Agreed. Great pocket power light. This should keep all dust out that may otherwise enter due to the loose lens. If you touch the lens in the process, you’ll want to wipe it clean. Be sure you use a LINT-FREE cloth, or you’ll end up placing micro lint particles on the inside of the lens.
So I got a pretty difficult request.
Does anyone on here have the CAD drawing for the BLF A6, and the Astrolux S41? Even just the head and bezel.
Sorry in advance if this is way out of line to ask for
Hi all,
I just received a BLF A6 driver from banggood, and I just have a couple of user questions, as I think my driver is not working properly. It seems to be in the 4 mode at the moment, so Low,Medium,High, Turbo.( Comes on in low I think, not moonlight) I can’t seem to access the config modes with 15 clicks, the light just keeps changing modes, I have tried both full clicks( ON/Off), and half clicks, but I never get to those 2 blinks that signifies config mode, am I doing something wrong?
If I do the medium press from the first Low, I get Turbo, and subsequently Strobe,Battery Level,Bike Flasher. Battery Level doesn’t blink, just constant low, so I guess it doesn’t work properly?
Any help/advice will be appreciated, thanks!
Flitsmal,
turn on the flashlight first (full-press)
then half-press 15 or more times, until the flashlight will do a sequence of 2 blinks. (observe first, don’t do anything yet).
Be observant when it does that “blink — blink”, pause a short while, then another “blink — blink”.
You need to turn off (full press) during the first “blink — blink” (after the 1st blink but before the 2nd blink) = this will switch from 7-modes to 4-modes or vice versa. (ie. blink — [turn off])
Now, to toggle mode memory, do the configuration again, wait for the “blink — blink”, then “blink — blink”)
(ie. blink — blink, pause, blink — [turn off])
Hi d_t_a,
Thanks for the quick reply, I have tried thanks, but it will not go to those blinks, it just continues to go through,low,medium,high,turbo. And like I said, there seems to be no moonlight
Don’t bother counting 15 clicks out, power it on and just half press it until it stops getting brighter.
From memory you have to start the quick presses from low mode and moonlight was only on the seven modes. Keep pressing quickly until the light stops responding to your presses.
On further reflection,I might have damaged the driver with over voltage, I was testing with a power supply, and a battery, and instead of using a multimeter on Amps, I accidentally added 4V from the power supply to the back of the battery… 
the bond wires on the led blew, but I am lucky enough to have those fixed at work 
So, I fixed the led, but maybe the driver was damaged in some way with the 8 V I combined whenI added the power supply to the battery.
It’s just the moonlight I miss really, as I still have at least 4 modes, with the quick access to Turbo….
Thanks for the inputs
If you’ve still got modes its still working.
Does this light have a lighted tail cap?
The modes were doing really weird things on one my lights after I did a spring bypass. I reflashed the driver and that fixed the issues. If you have the know-how perhaps you should consider doing that.
No lighted tail cap that I am aware of. I put the driver in my old BLF Eagle Eye X6.
No, I don’t re flash drivers, that’s just creepy/weird 
But it definitely has no moonlight now, I can’t get to the 7 modes or the configure modes, and the battery checker doesn’t blink, it just stays low( But I know it’s the battery checker mode, because it has the strobe before, and the bike flasher after…)
Cheers
Sounds like maybe the 7135 chip died, which would also cause the battery check mode and config mode to not look like they work. The amc7135 chips don’t respond well to excess voltage, even if other components survive.
I see. how do AMC7135 chips usually die? Aside from over-voltage? How about over-current? or other scenarios?
Usually just from excess voltage, which makes them overheat and burn out. Afterward they usually stop responding to the MCU and let a constant amount of current leak through. This would make all the 7135-only blinky modes stop blinking, and would make moon and other 7135-only levels all look the same.
Anybody know where I can get a new reflector? I had a little accident with mine I’m currently using a smooth S2+ one but it doesn’t have a groove for the oring.
I’ve killed more with excess heat [during soldering] than any other way.
I ONLY reflow 7135’s now, not that you can’t still overheat them but I find I have a whole heck of a lot lower failure rate with hot air then I ever did with an iron.
Is there a way to test the 7135 is ok, say with a multimeter? I suspect mine may have also gone as it appears to be stuck in the highest 4 brightest modes and I can’t cycle to the config menu.
You didn’t try to put a lighted tail cap in it did you? I know that will cause that problem if a bleeder resistor isn’t used when installing the lighted cap.
Nope, everything as standard. I believe the lighted tailcap issue is that mode memory won’t work correctly, i.e. mode memory will be on even if set to off.
