BLF A6 FET+7135 Light Troubleshooting and Mod thread

You are already in mode memory by the “second” set of 2-blinks. The “first” set of 2-blinks toggles the 7/4 modes. Turn off after the first blink of the first set of 2-blinks for the 4-mode.

Got it!

Thanks for the tip.

Shutting the light off during the 2 blinks in the configuration mode enables that option. So if you want to toggle between 7 and 4 modes, turn it off during the blinks on the first set. To enable or disable memory, turn the light off during the second set of blinks. I usually click it off between the two blinks, but even immediately after the second blink will do the job.

4/7 and memory are independent of each other, but it does take entering the configuration mode a second time to access either or.

I received my A6 and had the same issue with the switch never disconnecting, so the light was always on. Switch worked fine outside of the tailcap, but once any pressure was applied to the switch housing, which happens when the retaining ring is tightened in the tailcap, it never disconnects. Luckily I had a spare switch lying around that I swapped onto the board (no clue how many amps it can handle) to make the light work correctly.

I'm contacting the email address in the first post to see if they can send out a replacement. However, is this the best switch to go with? Is there a better one I can swap in there?

Side note: huge thanks to everyone involved. I honestly didn't read much about the light, just saw the specs and the huge amount of people in the group buy, so I ordered. I'm seriously impressed with the firmware, makes me jealous that TK was able to pack so much logic into one tiny 13a :)

This sounds like something we saw in our get-together in Oakland on Sunday. The rubber switch cover is too tight, so it presses ever so slightly on the switch, breaking the connection.

That's what I thought at first too, but it was actually a faulty switch. Just giving a heads up in case anyone else has the problem. I ordered a few switches from Mtn Electronics, so we'll see how they do (although the one I swapped in seems to be holding up fine so far).

Not sure if this is the right size. Pretty sure it would work. But I’m guessing if RMM carries it that it will handle direct drive. I also keep hearing about omten. But someone more experienced will know what you need.

Seems to have large traces :wink: and some via’s to help out the load.

I went with this, the Omten 1288, and will solder it to the included board.

Too tall by almost 5 mm. The mini omten is only 8 mm tall. It might work if you trim the rubber post in the cap.

Is there a red filter similar to the one below that fits the BLF A6? I think it’ll be useful with moonlight mode for stargazing or astrophotography.

I’m interested as well; with the 18350 tube it would be especially useful to use while fishing. I’ve looked around a little, but since I don’t know all the places to look for parts, I have no idea whether something is available or not.

Good Day Roadie, & Herb Tarlek,

Have a look here:

Nitecore Filters

Btw, Banggood & Fasttech usually sell them.

Good day George! Thanks for your reply. I found a 23mm inner diameter one for nite core, but the BLF A6 is 24mm. Are those thing somewhat stretchable? Or is there one for 24mm light?

G'Day Roadie,

I have the 40mm one, and it is made with a soft thick slightly stretchable black silicone rubber material.

Best Regards,

George

That’s awesome George! Thank you for your help!

Is this driver suitable for a (paralel) triple? The fet part probably is, but I doubt the other modes will be handled correctly.

It runs my triple fine.

I learned a few things. Get the proper copper spacer (heat management is very important for this driver), I probably won’t be running it with my 30q’s anymore (too many amps), don’t run d.d. too long.

I’m not sure if I have a defected A6 or if I just activated some type of mode I was unaware about. I seem to have lost the full click and release feature to turn the light off. Whenever I fully click to attempt to turn off the light the modes either downgrade to a lower level or upgrade to a higher level. The light will not turn off until the modes are cycled through. Then sometimes the light will turn off on a full click like I was expecting it to. Im just not seeing any consistency with the modes and it’s becoming very confusing. Does anyone have any thoughts about these issues I am having? Any help would be greatly appreciate it. Thanks

First check that the tailcap is not putting constant pressure on the switch. However for me the switch was bad and I had to swap it out with something else.

EDIT: Look at the previous page in this thread to find discussions about it.
