Upcoming Astrolux S42 18350/18650 quad w side button and usb charging

and for pre-buying w/o reviews ! :person_facepalming:

And what makes it worse is that it wasn’t the first time.

Yeah, I fell for it too…

Yeah, both sides haven’t learned form their mistakes… :person_facepalming: :confounded: :stuck_out_tongue: :partying_face:

has anyone tried removing the brass retainer ring from their S41 and installing in the S42?

It lives!

The mode changing is kill'n me! Guess this is why I wrote my own firmware... Why the delays? Ugh...

Any battery rattle or anything with the fix? Does it still want to crush the negative side?
Horrible with this lights regular price that this has been overlooked to begin with

Oh boy, definitely no rattle. Crushing the Batt- end? Well, maybe... It's darn tight in there. These are older EFEST cells, so might have been already some crushing. But it you see the cell sitting in the tube, just a little under the end, and knowing the tail spring has to completely collapse down to ~2 mm maybe, it doesn't look good.

So, the solder blob is probably not enough...

Could it be an assembling mistake?
Maybe that spring should have been put inside the larger one in the tailcap?

(edit) O, so it’s still a little tight in there?

I’m expecting mine any day now… :person_facepalming:

After the S41S crushed leds, now the S42 too short battery tube or whatever…

However, i ended up with a somewhat ‘free’ S41S after BG sent back a new head and agreed to sell the tail/switch part. Maybe we’re headed the same way again? Glad i didn’t pay the full price on this one.

I’ve no idea how to unsolder the driver spring without overheating the whole assembly… Can you share some tips?

Just do it.
Pull the spring while heating.
It takes a long time before the other side of the PCB is hot enough to de-solder parts, if ever.

sounds exciting….

Has there been ANY response from Astrolux/Bangood on these issues?

My buying habits hinge on good feedback…hint…hint.

I’m only VIP3 butt I might downsize next year

More pics.

Uh ohh -

Fits well using the S41 tailcap. The spring is soft and maybe set deeper:

That's about 1.5 mm clearance with the solder blob job:

Now we're cranking... A BLF A6 tube fits, reversed, then need to add a washer in the tail:

My S41 head is glued up real tight, never was able to get it apart. Least I can't break posts...

The tail spring is 1 mm diameter wire, sits in a 2 mm depth machined out depression. Full compressed it's still about 2.5 mm above the base (~4.5 mm compressed total).

Actually for mine, things are even worse. I tried bypassing the tailcap with a paper clip between the battery and the battery tube, and it still would not power up. The problem is that the *front*(emitter) end of the battery tube is too short (or the threads in the head are too long), so it never touches the negative contact ring on the board itself. I proved that by screwing the battery tube in *backwards* so that it made contact, and then I was able to get it to power up using the paper clip on the negative side. Inserting a circular shim in *front* of the battery tube, just ahead of the emitter board, yields a working flashlight which can also be tightened without further compression damage to the battery. This is clearly a design/fabrication issue, and I told Banggood in my latest email. Awaiting a response.

This setup works well for me. The o-ring is exposed though. With the solder blob on the driver, and the 1.4 mm thick copper washer shown above in the tailcap, the battery is not under stress.

Ohh - I managed to re-assemble the head w/optic with only one leg!

Oy vey, man, what a mad mod world :facepalm:

all of these work-arounds seem to skirt the issue of warranty (implied or otherwise)
we paid for working light, right?

Exactly!! Yet to receive mine but if it too is faulty I have neither the time, tools, skills or inclination to bodge it together just to make it function.

Still haven’t got mine, but i’m already preparing to write BG about it… Curious to see how it turns out.

damn.

Postman bought one today, but I ordered another as a present for someone…. which they finally shipped a few days ago and is on the way.

Not opened it yet, if it doesn’t work will be very unhappy as BG customer services seems to have disappeared of late - they canceled my order for the tubes with loads of points and still won’t give me the points back or even answer emails!

My first email to them was answered within 24h.

On their request I uploaded and linked to a YouTube video demonstrating the identity of the product and that it would not power up. Now, no response after the same period of time.

I had posted a negative review on the Banggood web site which they responded with a message indicating that this was a rare occurrence, and that CS would work with me to find a solution. Having additional information on the exact cause of the problem, I added a comment to my own review this morning. My comment was posted, and then disappeared several hours later. Perhaps there is a rule against commenting on your own review?
