2 pk description states
Simple 2 Modes: High: 100 lm(1h, 25min), low: 3 lm (25h, 15min). Twist the light head to switch the mode (high - low)

so which are these lo hi or hi lo?

Sounds like low-high, but perhaps Sofirn can confirm?

I recently received a high > low version, ordered from Amazon since I was already putting in another order.

I would normally strongly dislike this mode order, but I wanted a small light to carry at work for unexpected inspection needs. Basically, all I need for that is 50-100 lumens as conveniently accessible as possible. I tried just using the light on the expensive phone they issued me, but it doesn’t cut it.

The C01s is perfect for this need.

The tint looks ok - definitely better than the Fenix E05 I was using before, and high CRI. There is ring around the beam when staring at a white wall, but so far I don’t notice it in use.

The only flaw is that over time the moment comes that when trying to twist the light off, instead the bezel comes off. I know it is blasphemy, but the bezel threads need a drop of glue.

Seems to be more common to the BLF version. Have there been reports of this problem for the anodized version also? Thus far I was lucky with them.

Why is low 5 lumens now?

Just screw on the bezel first as hard as you can, then screw the head on.

No, you should not do that, already tried that, the bezel will reach so far over the pill that when twisting the light on, the bezel will touch the battery tube before the driver does, so it will not light anymore.

I’ve had this happen on both of mine. Stuck on in FET until I got pliers to get pill out. Can’t tighten body too much or else bezel will give in first like you say. I sort of agree but would never be the first to mention it

Interesting, I don’t have that issue with mine. You could try filing the bezel down a bit.

I thought about filing the bezel too, but I prefer a bit of glue in the threads instead.

Good to know. I will wait to loctite mine until I decide if I want to try any other emitters in it.

Asked via eBay if they were default low. Was told that they are default high

Edit: Asked if they had an ETA on default low and they gave me this answer:

“my friend, in November, C01S will have this version. (there be a version in default low mode)”

Please check my new interest check for a small-size batch of C01R (red light keychain light):

I asked about the posibility of new low/high batch yesterday and here’s the answer:

:wink: :+1:

Thanks for the info P33!!

anyone know any tricks to replacing the tail spring in these?

I ended up bypassing the stock spring for basically no gain. I did drop in a stiffer BeCu spring loose before I did that and got some gain (between like 5-10%) so I think the limiting factor is just the weak pressure of the spring which also makes it more smooth for a twisty so I decided not to go that route.

I bought this light, in blue color, directly from Sofirn 22 days ago, 2 days after I complete the purchase it said that it was “Shipped” and I received the tracking number. All good,nice.
But to my surprise after all this time the tracking number still shows “Logistic order has been created”. This is strange, so I messaged Sofirn asking about it and a lady said: “C01s is short of stock, so we have not send it yet”.

It’s not my first time buying from them and I never had a problem, but I think this is not the most correct way, they should have told me that before I complete the purchase. Or am I wrong? Did it ever happened to any of you before? On their page it says that they have 40’s units of each color, except red… strange.

Yes, it happened to me twice with Sofirn. Same situation has happened with BLF edition of C01S, they essentially told me where to stick it, didn’t even say they’re sorry. I understand that they are mainly wholesaler and manufacture for different brands but it would be nice if they would work on their customer service a bit.
