After checking just now it seems to be poor contact with the battery, strangely doesn’t affect High mode. When it starts to shimmer a good smack on the hand will stop it. I really hate that this battery can’t be removed now, it would be such an easy fix. There’s some movement / rattle inside from a little too much room for the cell.
I have a neighbors house at 1100m I plan on shining it on and could perhaps go for another neighbors wool shed at 800m. I’ll say that out with no light pollution it’s quite difficult to find the targets being such a tiny spot.
There’s a plate at the rear they have glued in place. Any ideas how I’d pull it off without gluing something on to pull? Can’t drill a hole since I’d hate to hit the cell
Yeah, the tiny spot size is why I haven’t been too interested in these overall, as impressive as they otherwise are. But if it can do a little at 700m then it might be worth it to me. Medium-compact throwers keep me happy now out to around 400-500.
If you have something furry to shine it on (without blinding the poor thing) at a good distance, that would be awesome, too…but not something too bright like a sheep.
Random note…have you ever seen the film/documentary called Sweetgrass? From some years back about herders in Montana…some of the last of the true mountain cowboy herders. I watched it last week for the first time and thought it was fascinating. I knew nothing about sheep other than a bit about wool fibers.
Maybe a soldering iron tip would loosen the glue? Is there any gap where a good thin spring steel hook/pick could fit…like the thin dental pick types but good quality.
Okay, this is a NCR 21700T which seems to be from Tesla.
There was a black sticker over the plate with holes to remove it. Not so good news is that it’s spot welder with wires, there’s no rear spring. I have a spot welder, so no issue for me, but everyone else won’t be able to replace it, should they ever need to.
I mean, I have the light right here in front of me - would NEVER have thought there was a sticker on the back. Perfectly applied i must say.
THANKS A LOT for taking it apart! Now I know exactly what to do, should I ever need it. :+1:
P.S. Regarding the replacement cells, if you’re EU based, NKON f.e. sells cells with tags already soldered on.
I got my SF2 in a week and half ago. Tested it on Medium and Low and I did get the shimmer you mentioned. It’s not as visible as yours though, and it’s not like PWM, but it is there. It does not do this on High mode. Not sure what it is? I don’t want to take it apart though.
Hmmm, well they’re sending me a replacement so I’ll be able to confirm whether it’s a fault on yours or it’s normal. They offered $5 usd per sale or a replacement once I reached $75, but they then offered one at only $25 in sales, so I grabbed it.
I don’t think there is any PWM, at least not visible with my camera up to 1/2000 shutter speed. My Armytek Wizard C2 Pro Nichia is visible at just 1/100.
