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.

Would be nice if Sofirn would reserve a small batch of 5mm drivers to sell separately to the unlucky.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

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.

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.

for future, the C01 w 5mm 670nm Red LED can be scuffed up without removing it from the light, since there is no glass lens.

imo, the C01 Red is pretty useless, has a low output, and terrible beam.. scuffing just makes it dimmer

I do not recommend the single mode C01 Red 5mm 670nm LED,
otoh

I Highly recommend the C01R xpe/sst 660nm red LED, it has a great beam, with 3 well spaced modes.

sorry to hear the light is broken

would have thought djozz son would have managed to break the unpotted C01 he tested…

Either your light was destined to fail, or your kids have more destructive skills than djozz’s boy

sad.. maybe it can be repaired, if its a solder joint failure…

gchart’s failure sounds like a broken component, not just a solder joint.. not sure

fwiw, the body colors of the 2020 C01 w 5mm 3400k High CRI Sophia LED that are potted are the
:
*black
* and *green
* models

Yeah, the ferrite broke in half. I’ll likely pick up a new inductor on my next Mouser order. Too bad, I just placed an order like 2 days ago.

I agree but using the diffuser makes C01 670nm much more sexy.

  • AAA-powered (Lithium-ion not supported. Unsure if it’s been tested)

I dropped an NiMH AAA cell into one of my C01s lights, thinking to see how well it worked, with the idea of saving a little on cells. It lights up, but only on low. I’m guessing the 1.2v is just too low to power the high mode. It will work great if all you are interested in is using the low for nighttime navigation around the house.

You don't really need a parachute to skydive. But you DO need one if you want to skydive twice!

The C01S works fine with NiMH. No problems with high.

Yes I use mine with only NiMH rechargables. I use the C01S daily and if the high mode starts to dim very fast after I put the light in high I just put in a new NiMH battery and recharge the old one. The light maybe doesn’t get as bright or works as long compared to non-rechargeable batteries but that’s fine by me. I always got some spares in my backpack anyway.

NiMH batteries have better performance than alkaline.

Do you know if this broke with the light off or on?

The djozz torture video has the light switched on, if I remember – with the light switched off, the cell can then move inside the tube and act like a hammer, perhaps what happened with your light?

Pretty amazing that that happened with such a small and shallow inductor. But children have special talents for these things Party

OK, I did my test with a cell straight from the package, so the voltage may have been down a little. I’ll throw the cells in the charger for a while, then test again.

I am embarrassed to admit this, but it wasn’t a C01S, it was just a C01. No wonder it would only have one output level! Dropped a NiMH into a real C01S and it works fine.

No need to be embarrassed. Thanks for clarification Thumbs Up
