Thanks. I’ll have a look at what I’ve got in the shed.
Pretty sure it’ll just be normal, copper, or silicone.
Thinking about it red rubber grease is quite stickly and I’ve got a little pot of that. No idea what it’s like on metal threads though as I’ve never tried it (for the obvious reason).
I've just ordered three, total $20.97, and got free shipping.
I’ve been carrying one of my C01S lights in my pocket for months, and have never had the head come off. How often does this occur to you guys?
Never
Never for me
Like the new version of co1 better than old one.
I also like the newer 3,400k Sophia better than the 3,200k Yuji.
The Yuji Tint seems a bit “muddy” by comparison and my perception is that cri is lower.
Stoopid question - I’ve searched but can’t find the answer, how does one remove the ‘driver’ and LED from these?
I’d like to scuff up the LED on my C01R but can’t get it out!
Cheers!
It’s normal, except the hotspot is quite bright on my samples. It’s just very narrow.
It’s glued. Brute force helps.
Whoops, turns out it was potted, tore the PCB off. Bugger.
Potted? Then it’s a C01, not a C01R. Big difference.
Like this?
Exactly.
Would be nice if Sofirn would reserve a small batch of 5mm drivers to sell separately to the unlucky.
Yes. And some hosts. OTOH, they’re still at $3.99 (white) and $4.49 (red). I think they are gifts to the community and wouldn’t expect any kind of service or spare parts.
Ahhh I was under the impression the red 5mm led version was C01R, I now believe the C01R is actually the ?SST ?XPE Version!
Ah well, perhaps it will save someone else’s light
I previously posted this at CPF, but might as well reformat it for BLF’s forum software.

Common features:
Well… somehow my kids have managed to bust the inductor on my 3-month-old non-potted orange C01. The body is nearly perfect still, so either is was just destined to happen or that C01 took just the wrong drop. :-/ I can’t complain for the $4 I spent on the light, but I guess that goes to show that being potted is certainly a benefit.
I think the battery hammering on the bottom of PCB’s during head down drops flexes the PCB and can crack solder joints. Drivers with springs on them are better protected from this, but space and cost are reasons for not putting a spring on the head side of a light like this.
My Sunwayman R01A (unpotted) died from a head-down fall from about 5 feet.
