C01R SST20-DR 660nm Deep RED Pre-order
C01R SST20-DR 660nm Deep RED Pre-order
SOFIRN83
color: Pack of 2
SST20 660nm version is a little brighter than the previous XPE2 660nm version.
hundreds of C01R with SST20-DR 660nm are in the warehouse now!
First come, first serve
SST-20 Deep Red is a bigger and more powerful led, so when comparing it in the same flashlight to XP-E2 Photo Red it should have a bigger hotspot and be somewhat brighter.
Received today via USPS. Seems like a good niche flashlight. Three levels, nice build, smooth threads.
My only other red flashlight is a 4Sevens Preon 0. The Preon is floody, whereas the Sofirn has a focused spot. The floody Preon will be more appropriate for reading a map or star chart at close distance, and the Sofirn will be better for distance work; hunting nightcrawlers, or navigating a trail. The Sofirn C01 build quality is wonderful. I lubed its threads with SuperLube, and it is very smooth. I might buy a couple more as gifts for my camping friends.
My two arrived today via Royal Mail, twelve days after Sofirn shipped it.
Lovely little light. Considering adding a red tritium capsule to one of them.
I put a little Nyogel 795A damping grease on the threads. That improves the feel of the switch. Worth doing if you have some on hand. Not worth it if you don’t already have some. Light works fine stock.
I have both and the SST-20 does indeed have a larger hotspot, but the difference in brightness is less than I expected. I will try to take a few pics after it gets a little darker.

Hi,
I just got my two C01 with Cree XP-E2 Photo Red (see photo) directly from the “Sofirn Official Store” on aliexpress.
The brightness is as expected and the colour seems really to be redder than standard red LEDs.
(Picture follows, if I know how to upload one …)

Very close to being the same at least to my old eyes. Sorry no beam shots - I managed to step on a nail and drove it deep into my heel - had to pry the board off - will be off of my feet for a couple of days
For me the perceived brightness goes to the XP-E2 because of the smaller hot spot and less spill, but that’s not the whole story. It would take a lumen tube for me to be sure.
Nothing bad happen at driver if I put White SST20 (2.5-2.7 Vf ) on C01R?
Need sublumen
I replaced the stock XPE2 Red with a SST20-2700K. The result - massive output drop - the HI is now about 2 lumens(with prolonged runtime about 30 hours). The lowest output is identical with “0.01 Lm” on Zebralight SC62W, and runtime about 4,5 days.
So Max is 2 lumens? Guess I’ll be leaving it as red.
So strange,maybe driver can’t deliver right Tension at Led,but I’m not expert.
Would be interesting know Vf and Led Current.
THX for report :+1:
SST-20 white @@@ 350mA 2.5V - 3.1V, 2.73V typical
SST-20 660nm @@@ 350mA 1.8v - 2.6V, 2.05V typical
Maybe this driver maintains a target output voltage rather than a target current, or output voltage is capped.
Can’t wait for mine to arrive. MixGlo is out of red tritiums for now so I went with a pink!
I wonder if that 3 mode driver with reversible modes will make it into the regular C01S.
Am I the only one feeling stressed under deep red light? I see stars before my eyes, and after exposure my perception for red is mostly gone. It doesn’t hurt, but just does not feel good. For reference, I used max intensity of the C01R indoors for not even a minute. Maybe too much.
Just curious how others feel.
I feel slightly disoriented when using red light.
It does that in the beginning. I had the same feeling but after few days I got used to it. Now I'm only using 660nm for night activity of any kind. White light got a big distraction now.
Maybe the cause is the Narrow band light that over some lumens alters your perception.
Hope your problem is momentary as I keep seeing red for a while.
Be cautious to use max power with C01R and others native colored Leds.
