Buy a Nitecore Tube. It even has ramping and can take one of rngwn’s power LEDs without modification. Beautiful light, btw.

In tiny 5mm hosts i personaly don’t want extra electronics to fail on my keychain.
Simple as possible, one mode.
Better look for C10S
Please Sofirn: with memory mode, forward clickie, support 3.7V, no visible PWM: Sofirn SF01A was a perfect mini-tactical light!
Why C01 does not use socket pin for hold and swap easy Led Intead of solder?
Anyone know an amber emitter suitable to swap into a C01R? (Or anyone interested in doing a mod for me, as my old hands have gotten shaky for small size work)
Mtn Electronics sells the Cree XP-E2 Amber and PC Amber on 16mm and 20mm MCPCB. These two are in the same family as the current C01R LED.
It was made for maximum durability, and hence it was potted. So, no luck replacing the LED easily (yes, can be done, did it with a Fenix E01, but it’s not funny). In addition, a socket (part and work) would have added to the cost.
New C01 will not have a potted driver, but I guess cost is still too much. But a really good idea to get people without soldering iron interested in hosts.
Din’t watch inner head of C01.
I would liked Led can be placed like incan. bulb.
Considering the small space using pliers instead solder.
There are host like that for 5 or 3mm Leds?
Hope there will be one day
kaidomain offers them reflowed onto a 10mm mcpcb
I would be interested in seeing some photos of a C01R teardown, and to learn if 10mm fits, though I dont mind reflowing onto a stock board if necessary
I note this C01 thread is about 5mm LEDs. I welcome a more link to a more appropriate place to discuss the power LED version, such as C01R
Looks like C01 with emitter pre-installed is coming out in a week or so.
Very exciting news!
Sad however that the thread also appears to confirm that there are no immediate plans to release a host version
Sofirn replied in that thread that 5mm emitters will be swapable...wink, wink
I intended to offer 30 or so Yuji-C01 and a couple of warmer tints. Not sure it pays considering desoldering the LED first. But for sure, I’ll buy some for myself, and I’m especially happy the 670nm version makes it into production.
Definitely in for three of these.
Sofirn said they are not making a C01 host, and that other led’s were a matter of swapping.
I just ordered a couple of C01’s with “standard” led, and will do the swapping myself.
So I unsubcribe from this thread. I would like to thank djozz for all the effort he put into it.
Thanks from me, too!
You are welcome 
Since the new C01 is not potted, the relevance of a host version, although it would still be convenient, has become less: swapping the led can likely be done by prying the driver/led out, solder in a new led with a common solder iron, and pushing it all back in place.
Only thing: there was some confusion about wether a o-ring around the led is in place to waterproof the driver cavity, I hope that this is not true, at least the original prototypes of the C01 that I own do have that o-ring.
