Looks fantastic in raw aluminium. You can see all the machining marks, especially on the tail. Beam is very focused for an AAA light; im surprised. I really like the tint. Mode spacing is indeed low - high
For me itās great in stock formā¦ I could imagine others wanting to make it floodier or put in a warmer emitter though. 3000k SST-20s in particular.
Did Sofirn ever make a Low-High version? Thought that was in the works at some point. Doesnāt bother me too much, just thought it would be more practical.
Itās set up exactly as it is stock, except with a glass lens to keep it waterproof. The TIR optic is within the plastic insert (I assume to reflect light that escapes the optic) so all I had to do was remove the optic and add a lens.
Arrived my new C01S raw Alu, nice ānudeā lights.
The new arrived:
With her systers:
By the way, at this moment all my Sofirn lights work perfectly with 10440 of 3,7V.
C01 gives the same light with alkaline as with lithium. I have only tested momentarily. C01S and SF01 are transformed into small cannons of light, with fantastic WOW effect. I have been using C01S and SF01 with lithium for several days at home for many minutes every day and they work perfectly and they also continue to work with alkaline batteries and with ni-mh, although I like them much more with lithium!
The C01S supports āhoneycombā lenses that smooth the contour of the light beam, such as the old Fenix E05 of 27 lumens:
