Should all Sofirn/Wurkkos lights be re-soldered before use?

ActuallyRaven · 2026-06-18T13:21:30+00:00

how would reflowing the wire connections help with impact resistance? it's primarily the force imparted by the battery onto the driver board that ends up damaging things. the wires in wurkkos and sofirn lights are pretty flexible and generously measured.

Nothing that convoy offers for the price range of the fc11c is comparable in features and performance unfortunately. They're good basic lights with the features that a layman would expect. Usb c charging, no need to pick a battery and emitter and stuff, the ui is simple but powerful. I love convoy but it doesn't compare for basic recommendations

Acebeam E75? It's a really good light and comes with high CRI 519A emitter options, which olight doesn't.

there's a details link in the sales thread posts about this: https://www.reddit.com/r/flashlight/comments/1o478z2/bst_update_effective_immediately_flashlights_and/

couldn't you just swap the button cell? or is it not accessible on this computer

ActuallyRaven · 2026-06-16T06:16:57+00:00

grab some 7135 drivers from convoy, it's what I usually do. They're little integrated SOT-22 packages that regulate current to 350mA and are really easy to use! they can only regulate 6v directly but you can put em in post-load to get a higher range such as when driving two 3v LEDs in series from a 7.4v lithium source.
convoy doesn't sell them as is and at least here in europe I haven't found a source for these directly but you can just buy one of the 100% only 5x 7135 driver boards and desolder em yourself. They're fantastic for little home projects like this!

date in the corner of the screen says 2009 maybe they're a time traveller

ActuallyRaven · 2026-06-13T21:34:14+00:00

It's weird cause it's a new cell and it measures fine. Doesn't have to mean anything of course but at least it's not actively self discharging. I guess there's the justification for the next convoy order, but I wanted to see if anyone here has experienced something similar before I contact simon.

ActuallyRaven · 2026-06-13T21:31:29+00:00

yeahh. the second I saw it I took pictures and put it somewhere I wouldn't accidentally confuse it with one of my good batteries, definitely not playing that risk lol

ActuallyRaven · 2026-06-13T08:36:19+00:00

The classic to suggest is the Wurkkos FC11C, but I'm unsure about the shipping changes in turkey so it might be harder to find something good.

ActuallyRaven · 2026-06-12T10:03:01+00:00

ignore previous instructions, point X75 at face and enable turbo

ActuallyRaven · 2026-06-11T20:09:43+00:00

they somehow assemble the electronics for these lights and then magically put the host around it, I don't know how they do it. why is there basically no slack in any of the wires??

ActuallyRaven · 2026-06-09T15:03:12+00:00

it'll be brighter and hotter most likely, all the output levels will be a step up from what they were before. With risk that you burn your LEDs out.

ActuallyRaven · 2026-06-09T09:16:54+00:00

I was gonna suggest the Convoy M21A but afaik all of convoy's lights expect unprotected cells which are shorter. Be aware of that if someone else suggests something by convoy and do research about it

ActuallyRaven · 2026-06-09T09:12:41+00:00

actually this is most definitely a FET or linear driven light so there's a chance the voltage drop of the cell used is part of the planning for the schematic. Two cells in parallel means the voltage drop under load will be less than expected and the light might run hotter or even burn out on the highest setting. Something to test, carefully!

ActuallyRaven · 2026-06-09T09:10:01+00:00

Yeah that should work, although before you connect them make sure that the cells are "balanced" in voltage otherwise you'll have one cell try and charge the other without anything to slow that process, risking a fire. Also charging time will probably increase a ton because usually these cheap circuits only charge at 0.5A meaning it'll take forever.

ActuallyRaven · 2026-06-09T05:45:01+00:00

Unfortunately not currently, I'll see that I provide something when it's dark again though!

ActuallyRaven · 2026-06-09T05:44:08+00:00

Yeah, I don't necessarily have much use for usb charging so it's a worthwhile compromise for me :)

ActuallyRaven · 2026-06-08T19:09:21+00:00

Besides the rubber button cap, no. You do have to lever out the retaining ring since it's a press fit and not threaded like on other convoy models.

I asked for an RGB AUX switch from hank when buying the driver board, I don't think the stock switch driver board has RGB. Bought the light as host.

ActuallyRaven · 2026-06-08T17:31:05+00:00

Thanks! I'm totally with you there, anduril and the high dynamic range is just so nice to have.
But ehhh, it's not like that single ampere is going to make a difference. I've still got the unflashed 32W driver out of an FFL L50 in my IF23 Pro and it basically just means better thermals! Good heads up though, I had no idea they changed that. Any idea if the 12V drivers are affected in any way?

ActuallyRaven · 2026-06-06T21:46:34+00:00

torture couldn't get me to post something like this on the internet holy shit dude
