Ordered one of each available for now, many thanks to all involved in making it happen. Looking forward to seeing them, I’ve an E01 i have always loved for it’s robustness but hated the tint, hopefully this will cure that!!

Had a first look at the potting, and it seems like there’s good news for potting fans (and bad news for modders) : I tried poking with a needle at the side of the driver where the compound is exposed, and into the insertion hole in the driver, and on both positions I hit hard solid stuff. So at least the driver/led cavity is fully watertight separated from the battery compartment and at best the whole cavity is one hard brick of potting stuff.

I’m not ready yet to break a C01 open to see which one it is.

I can confirm this as well with my production run C01s. When poking with a needle the white stuff feels hard and solid.
When comparing a Fenix E01 with a Sofirn C01 the potting material looks similarly white.

Did Sofirn ever communicate what material they actually use for potting the driver?
Some kind of epoxy, or some other material?

If it is white, it is usually thermal epoxy.

If it is transparent, it is usually potting compound.

Hopefully Sofirn did the same as Fenix.

Edit: I mean in terms of reliability, not in terms of moddability.

Somebody should nudge Sofirn about communication.
BLF isn’t just a place to harvest potentially profitable design ideas and ignore what people want.

Have they been doing that??

I am under the impression Sofirn has been very responsive & open to what people want.

But maybe it is I who am uninformed?? Are you referring to anything specific??

There is of course a large overlap between harvested ideas and what people want. And communication with the chinese manufacturers will always be difficult, for numerous reasons. I can’t exclude stealing ideas without giving back proportionally as a motivation for contact but as far as I was involved with Thorfire and Sofirn, there’s more going on, not just profit, it is combined with a will to make a good product too.

Received my three samples 3200K today. Very nice, good anodisation, I can see the potting over the side of the driver and trough the hole of the PCB, it seem very robust. I can’t (at the moment) pull out the driver. The clip is very strong, and it is not dificult to remove it.

Very good keychain, very good purchase, it’s a shame it’s not easily modifiable Smile

Yeah, potting that prevents modding is a misfeature.
It’d be a favor if they’d offer hosts or moddable lights.

As noted above,

Because of the potting of the electronics….

It’s good though.

I ordered the 2 C01’s when they were announced available in this thread, it was spotted by d_t_a, 10-11 probably.

After the comments by you and djozz I looked closely at the clip on the production C01.
So regarding communication: it seems Sofirn listened to feedback by djozz and improved its design.

However I would still advice to remove it the correct way: at the ring where it attaches to the flashlight, either by using a small screwdriver or by using both thumbs to push it off at the open side of the attachment ring.

And not like I did by using the “tip” of the clip as a lever to push it off (learning moment…) Facepalm

I wish they (or someone) would make inexpensive* addon clips like those made for the 4sevensPrion or the Solarforce lights —attached by dropping a complete ring over the tailcap threads.

*Here’s an expensive, likely bombproof, version: https://darksucks.com/products/eiger-titanium-clip

I like those clips too, but the C01 has no tail cap. An advantage of the current clamping type is that it can be reversed.

> no tailcap
Yeah, those also fit over the head end threads.
But yes, agreed, reversible is nice.

I’ve just snapped too many belt clips by carelessly getting too close to something that grabs, torquing/twisting the flashlight.

I ordered the lights at AliExpress on 2018-11-10, and received them on 2018-11-26 in the Netherlands.

With a clip attached this way to the C01 it would not turn on as the driver board would not make contact with the inner ring inside the battery tube.

 

Perhaps an Arc AAA clip might fit? That design looks quite bomb proof and reversible (source).

 

 

The GIU uses a similar design.

Thanks for pointing this out. I edited the Specifications post accordingly.
Perhaps in the future Sofirn might share with us the potting material of the C01.

I had some trouble opening the test videos uploaded by Sofirn to YOUKU.
Great videos so I reposted them on Youtube, and added the links to the Opening Post.

I am still amazed at how ingenious the Sofirn C01 tailcap design is given the size constraints and all the included optional functionality. Thanks djozz and Noir! I presume this is the most advanced tail cap design of any currently available AAA flashlight.

Like djozz stated earlier:

Quote:
I honestly also think the tailcap is not really important for a 6 dollar light, but because we may have the opportunity to take part in the design of it I think it is fun and worthwile hobbytime to spend a lot of thinking time on it and see if we can do it better than all other manufacturers who also do not take the time to think long about the tailcap of their 6 dollar lights.
And the best fun is if our tailcap design makes its way in other manufacturer’s designs.

Ordered november 10, received today 28 in Spain, it is a very decent waiting time. With tracking number.

When i saw the first image of the tailcap, I thought it seems ugly, but now I love that little tailcup LOL

To set history straight, the idea of this tail is all Noir actually, I just took part in the discussion about it and translated his drawing into accurate dimensions to be sent to Sofirn. Here’s his drawing that had all the details already:

Ha. I actually just posted in the other forum and asked Fenix Store if the E01 has been disco’d. Still waiting on my Sofirn and good to hear that the “frosting” has hardened up nicely Big Smile
