Can anyone help me on how to dismantle a Convoy C8?
I just purchased one in a lovely warm tint, and am thrilled with it in all ways except that it won’t let me shut off the blinky modes.
The seller suggests that the best solution would be to solder the 3rd star on the Nanjg 105c driver (as explained here), to lock out the blinky modes permanently. I am happy to lock them out rather than just disabling them, so the mod is fine, and I have no problem doing a little soldering. It seems like less hassle and expense than sending the torch all the way back to China.
However, the driver on the C8 is partially covered by a sortofa ring, which means I can’t see the stars let alone get access to them with a soldering iron. So I guess some further dismantling is needed.
On the other end of the head, I can unscrew the lens, which allows me to remove the reflector and expose the LED. There are two screws which secure the emitter’s mount, but that’s all. Will removing them help at all?
I am beginning to think that this is a more difficult job than I thought, and that maybe I just ask the seller to take the light back. But can anyone explain how to get a soldering iron in at the stars if I do try to fix it myself?
Hi Jim, I know that. I have several other Convoy torches which work that way (S1, M1, another c8) , and this one is supposed to work that way.
The problem is that it doesn’t work that way. I have tried repeatedly to find a blink in low mode (waiting for up to 60 seconds), and tried switching it on and off in low mode after various intervals. All no go, which is why the sller eventually suggested soldering it.
Also, on the Convoy C8 I got, I had a heck of a time getting the bezel off. I thought that it was glued, so I opened a ticket with FT and they claimed they contacted the mfr and that the mfr said that they didn’t glue it. I think put more effort into getting the bezel off and eventually came off with nitrile gloves and a LOT of grunting :)…
I've had trouble unscrewing the bezel off Convoy lights before too. At a grocery store or place like Walgreens, or even Amazon, you can find a gadget that helps unscrew over-tight jar lids. Usually called something like "Rubber Jar Grip". It is basically a thin square or round piece of flexible rubber. It gives you a very good grip without marring the finish. Get two. One for each hand. Never fails.
I’m at the same stage Bean. I can’t tell if the retaining ring over the driver is screwed on or slides on , but it definitely has a ton of white glue all up in it.
I seem to recall a good strategy for unscrewing glued bezels involving dropping the item into a ziplock bag and dropping the sealed bag into hot water for a bit, then using gloves to twist them apart… No idea if this would work on thermal glue seeing as it is designed to withstand heat.
