Thanks TK.
Lvp will work with other firmwares or it will need modification?

Depends on which firmware. In most cases though, you’ll at least need to set the LVP threshold to match the physical driver it’s running on. Those values change from one model to another, between brands, etc.

Thanks to DB Custom (and other posters that I can’t locate) for tips on improving my bypass:

Turning off the turbo timer on the BLF-A6 requires flashing modded code onto the driver. The code is available, but it needs about $10 or $20 worth of other hardware for the flashing process.

I have the Astrolux version and it recently gets a spring bypass upgrade.

It gets hot much faster now and gets uncomfortably hot after putting usage.

Is that normal it there’s something I’m missing?

So… it sounds like the spring bypass worked. Thumbs Up

Looking to do the Spring mod but notice something odd with my tail cap switch… It has the main spring as it should do but the is a smaller spring made if thinner wire loose (see attached image)https://1drv.ms/i/s!AmKZHSJEsyYco00q9s6AvQ0_K6eu

Anyone know why or what it’s there for????

The inner spring is for lower resistance and higher amps / lumens. But it should be soldered to the board of cause.

If you do the spring mod (bypass with a wire), the inner spring is not needed, it will not do much. You can just remove it if it is loose already.

What is soldered can be unsoldered no problem.

Sometimes the answer is in plain sight. Big Smile

I still think for that specific light, your firmware is just about perfect. If that light is putting out 1500 or 1600 lumens and is triggered by accident in your pocket, 30 seconds step is very much appreciated. Fun fact: my mother in-law saw my a6 sitting on the coffee table and turned it on and didn’t see any light so clicked it on off, then looked into the end of it and clicked it again. That was honestly a slow motion train wreck that I had no intention of stopping. Priceless!!
Thanks TK, I love Bistro but the blf a6 and associated mother in-law stunning will forever hold a place in my hall of fame!

As it turns out, the mother-in-law stunning is a pretty well-documented part of that light.

I did that to my sister with an Astrolux S41S. I was wearing it on my belt, she was curious about it, so I handed it over. Never even thought about what would happen next.

click puzzled look click pause click
NOOB COUNTERMEASURES ACTIVATED

Once and once only. I simply don’t let anyone touch my A6-class lights now.

After all, I have plenty of nice, safe BLF-348s and sub-500 lumen Convoy S2+ lights for them to play with instead Smile

Bistro requires tiny25/45/85, and won’t fit on a tiny13.

BLF-A6 works on tiny13 drivers but requires an offtime capacitor (OTC), and prefers two power channels.

Biscotti works on single-channel tiny13 drivers like Convoy uses (nanjg/qlite/FX-12), with no extra hardware. There are also a bunch of others which work on Convoy drivers, like gchart’s “babka” and _the_’s “TheStar”.

The “INDEX” file in the firmware repository has more detailed information on all this.

No problem, no mod
The Bistro has the bleeder resistor

It is the 470R (471) on top, beside to red wire

In the BLF A6 you must add the bleeder resistor

Sorry for my bad English (gogole transtorla)

But it does have the NMM with the lighted tailcap, works fine with normal one.

I’m unsure of the o-ring size but the A6 uses 14mm tail caps.

I have one of the above installed and it glows brighter than Convoy’s glow-in-the-dark tail caps.

Hi, my first post.

I recently got 2 A6 from banggood on sale (16€ I think)
I got the warm and the white version. Now the white verson blinks much slower (strobe,bikeflash, bat check)
I seem to recal reading something about old drivers beeing under-clocked when i did my research, but i can’t find it anymore.

Is there a fix? did banggood just dump some old stock on me?

If I would replace the driver, is there a ramping alternative? (I really like the Q8 software)
