I don’t remember there being any discs that screwed into the carrier. Are you talking about the ones that are soldered in? It was mentioned on the MF01 thread that those discs were not soldered very well and it was fixed by heating it up and soldering it back in place.
If you can’t solder than they can probably replace that battery carrier under warranty.
It also sounds like there is still an issue with the driver or a bad ground or something. You might try loosening the driver ring (or screws, we have not seen this lights internals) and poke around. Then put it back together. Sometimes that can get things working.
Hopefully this is not going to be a big issue requiring the light to be replaced.
No, i haven’t received mine. But i am alarmed to see it can’t be switched off. Just like something happened to MF01 that i read previously. I haven’t used any flashlight that can’t be switched off, to me, that’s very unacceptable.
Oh, your easily alarmed. You gotta take risks if you wanna save a few dollars with these preorders. Otherwise, it’s best to wait for reviews and such to see that everything is okay.
You can still buy the lights later on with coupon codes, but it might be a little more expensive. Like instead of $78 now, it might be $84 to $88 later with a coupon.
Sometimes I’ll take a risk if I know I can get a replacment driver for it. With this light, it’s a special boost driver and neither Lexel or anyone else has a replacement for it.
This is the small disc that I mean, inside the plastic ring. As I said, it can’t be the problem, as the light shows the same problem with both carriers (MF-01 & MF-02). But I wonder whether maybe the disc or the screw caused a short when they became loose?
Switching on and off is the most basic and important feature. Because I don’t follow MF01 thread anymore, I don’t know is the root cause identified. But I don’t expect to see it in this MF02. That’s also why I don’t buy a 2nd UT01 that’s having switch on problem…
I believe that someone had previously posted pictures of the disassembled carrier in one if the threads. On my phone right now, but maybe someone can post the link.
It IS up to you, though. It’s part of the process. You check all screws and rings to make sure everything is tight.
The quality control on Chinese flashlights can be iffy, plus the long distance travel can cause things to loosen up. I do it on every light I purchase. You learn this from experience and it’s passed down to others so they can learn before a bad thing happens to them.
No worries, though. It’s not your fault. The driver problem may not even be related to that brass cap.
Here is a picture that Lexel posted on his mf01 preproduction review.
I never realized what that little piece was in his picture. Now it makes perfect sense. The pcb’s on the end make the center rod and the brass caps all positive. The outer rings and 4 outer posts are negative. Hence why they are covered in insulating heat shrink.
Just a comment for any UK buyers here. My MF02 which is being shipped from Singapore is being held by DHL customs because the shipping company is under HMRC investigation for customs evasion. This is because they declare a lower value on the package. I have to send proof of purchase price (and obviously pay a charge) before I can get the torch.
It’s a hassle I don’t need.
Strange that my light was already at the Royal Mail delivery office in Birmingham on the same day that it was marked as ‘shipped’ by BG (which was later verified later by Royal Mail tracking).
To use the GT driver on the MF02 and MT35 would require rewiring the battery carrier to all series to get 12v. I’m not sure how hard or easy that will be.
All right, that’s good news. Do you know of any threads showing how to do it? Is it just cutting traces and soldering wires or do you have to order new custom pcb’s for the carriers?
