A pleasant surprise was found in my mailbox today. Just nine days after the shipping notice from Sofirn, the little deep red light arrived today. For the price an absolute AWESOME little torch. Well packaged, two O-rings included and and even the detailed manual. I couldn't be happier and will test it at my next telescope watch night. The spill is very even and I absolutely like the low-mid-high mode. The first will probably be enough for my purpose, high is pretty bright, even under daylight conditions. Once it's gettin dark I will disco today! Wink A big thank you goes out to Lux-Perpetua, Barry and Sofirn. After the delightful LT1 now this little gem - I absolutely appreciate the fruitful cooperation between BLF and Sofirn (and of course spread the word)! :-)

Thanks for the credits and many thanks to all of you for your confidence in this whole idea of a deep red keychain light. Without your interest this light would not have come to existence.

My C01R is still en route, so you will probably have the great honor to be the first to share some impressions with us on BLF. Smile

I'm not sure if it is allowed to link - just google: taschenlampen-forum c01r and use the link in post #124. High mode indeed gets warm very quickly.

I just read that this user measured following currents with an 1.45V AAA Eneloop battery and a Mastech MS8268 multimeter:

Low = 15mA

Medium = 105mA

High = 2.500 - 2.800mA Shocked (no error with the decimal point)

I’m flattered! Wink
Being not completely infected with the virus, I have just a limited number of lights to compare. On the left the SP32A V2 as low as possible (XP-L2 5350-5700K), the C01R on medium power and on the right the SP40 as low as possible (XPL 4000K). I did what I could do to capture the correct color impression of the anodized C01R body.

Why should it not allowed to direct link?

Seems like Barry liked my idea of “multipack of C01R” Party and he is including a discount. Smile

I was just wondering why the C01S says “ Maximum purchases of 1” when you try to get more.

I tried adding multiple C01S to cart and it seems that you can order one of each color in the same order if you want more than one.

Received mine yesterday (13/07 in Australia). Shipped on 04/07.
Great light, thanks Lux-Perpetua for the project.

The shipping is much faster from Sofirns website than the Aliexpress store.
Purchased a SP40 and it was shipped on 30/06 and still not in the country according to the tracking.

Alll the red body is made for C01R, there is no C01S in red body now. 

 

It was supposed to be "wine red" but the anodizing factory told not possible,

 

but I ask them to make it as close as they can, here is what we have: not as deep as "wine red" but deeper than the former red body.

 

Please know that the color varys in different screen.

Also there are new colors: Orange, Blue (deeper), Desert Tan, Green(picture will be updated soon)

Unluckily, my country is not applicable for the discounted Sofirn C01R (I ordered when it was priced at $7.99)..

I went to SofirnLight.com to purchase the Sofirn C01R, but also saw some other items there, and purchase those other items.
Now the other items are shipped out (but not yet arrived), there is a message that the C01R is not yet ready to ship.

But now, Sofirn emailed me that they cannot ship the C01R to my country, and instead I need to purchase using another Southeast Asian portal site, which has a higher price (equivalent to the $9.99 price). I’m not sure if the $7.99 will be refunded to me, or they will find another way to ship to me.. Sad

Barry and Sofirn's engineer were so kind to check these observations. Their feedback is as follows:

The maximum current is a little more than 1A. The lower the voltage is, the higher the current gets. The multimeter makes the voltage much lower, that is why the current is higher.

 

My lay assumptions along with their feedback:

  • The current was not measured directly at the LED (i.e. behind the boost circuit which regulates voltage and current to meet the XP-E2 photo red forward voltage of 2.4V) but via bypassing C01R's tube.
  • The current was not measured with a clamp meter but with a standard multimeter. Most probably the voltage significantly dropped as the multimeter has an internal resistance which effectively distorts the measurement. Eventually, the boost driver had to regulate this lowered voltage by increasing the current up to 2.8A (which is the typical behaviour of boost drivers).

Maybe there’s a difference, hard to see. But thanks for fast shipping!

Edit: The high mode is blinding. Good job Thumbs Up Beer

As long as there’s something red coming out of the front it’s fine with me. Mission accomplished.

Hi, I am the_holodoc from TLF,

I have got my light yesterday and posted a bit about it over at the TLF: https://www.taschenlampen-forum.de/threads/sofirn-c01r-1xaaa-rotlicht-66...

I will try to repost an English version of this over here, so that you can see the pictures as well. I am sorry if this post is a little rough on the edges, it’s my first post over here.

This is the packaging content:

Among 1xAAA colleagues: from left to right: Olight i3E EOS, Sofirn C01R, Olight i3UV EOS

Comparison of beamcolor: left: Sunwayman C21C, right: Sofirn C01R

Brightness comparison: left: Olight i3E EOS, right: Sofirn C01R on on its highest level

Brightness comparison: Zebralight SC600 with some diffusion on its 0.2 Lumen level, right: Sofirn C01R on its lowest level

Beamprofile:

Bounced flash:

Sofirn C01R:

Current measurements:
AAA white Eneloop (800 mAh), charged to 1.45 V and Multimeter (Mastech MS8268) with just the original cables and tips. At high currents some deviations due to contacts resistances adding up are to be expected, so take my result for the highest level with a grain of salt!

Low mode: 15 mA

Medium mode: 105 mA

High mode: 2.5-2.8 A

Today I improvised a little to obtain a brightness-runtime-graph for the highest mode.
I used the following setup: The light is surrounded on five sides with A4 sheets of white paper, it is tailstanding to light up the white “ceiling”. Next to it I put my smartphone (Pocophone F1) using the App “Physics Toolbox Sensor Suite” (mode: light metering, digital display, I recorded the data during the measurement, but I ended up not using these records), the automatic switch-off of the display was disabled.
I photographed this setup with my Olympus OM-D EM5II using the built-in Intervallometer every twelve seconds with fixed exposure settings (ISO 200, F/5.6, 0.5 s).

Setup without the light with room lights switched on:

Setup at work: roomlight is off, reading of remaining ambient brightness is 0 Lux

The Sofirn C01R was equipped with a white Eneloop (1xAAA, 800mAh, 10 years old). The Eneloop was charged fully half an hour before the measurement. Right before the measurement it had a resting voltage of 1.47 V. After the run the hot cell had 1.12 V. After letting the cel cool down I charged it with my Miboxer C4 V3 which showed, that it had charged 720 mAh.

Overview of every third image with each also showing the time when it was recorded:

The resulting brightness-runtime graph (readings from the images, sthe steps apparently stem from a low measurement resolution of the phone):

After a little over 15 minutes the light switched down to its lowest mode, which ended the measurement. The light was pretty toasty afterwards.

The readings for the current draw on the highest mode where apparently not that far off. It drains over 2 A from the cell to deliver that much power to the LED. On the highest mode it’s a nice little red dragster and on the lowest mode it is a sensible choice for preserving the eyes dark adaptation.

I had expected a bigger visual difference between the Sunwayman C21C red (most likely around 625-630 nm) and the Sofirn C01R with it’s 660 nm emitter.

During a round of urban astrophotography last night the lowest mode proved to be not to bright although it could be a little lower for that purpose. I guess I will have to get one more C01R for a colleague of mine…

Resume: I like what came out of this project! Good job to all contributors!

Kind regards
Frederick

Got mine today. Shipped at 4th of July so shipping was fast. Going to keep this beautiful light right next to my bed:

Also works great with Thrunite’s diffuser cap on backpacks when going outside when its dark. Its only on low mode, but more than enough for cars to spot me and runtime should be great.
Lovely little night light this is:

Not sure if I’m going to need high mode because medium is pretty bright already:

Well high mode has a bit of wow effect though and maybe useful when navigating outside just with red light. Thanks for everyone who made this light possible! Thumbs Up

Despite no updates from USPS tracking saying it had even showed up in the U.S., my C01R lights showed up today. Very cool little lights, bright is quite bright as others have said, excited for night to roll around Thumbs Up

I had to create 2 separate orders to get 2 lights (one for me, one for the brother-in-law). I guess that’s to double the take on shipping cost?

I think it’s an issue with their website to be honest. I just went to the cart and adjusted the quantity as desired from there. Same trick worked for the new colors of the C01S that were just posted.

My little redhead was shipped on July 4th, but is since 6 days living a quiet life in Luxembourg (?).

.

Edit: after 6 days, and almost 3 hours of R&R it appears to be on the move again.

.

Edit 2: Ahem, it only apperared to move. After 10 days Luxemburg and 1 day The Hague it’s now in Amsterdam since July 22nd. PostNL says they (still) have not received it.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

Glad you worked it out!

Forgot about the eBay store.

I wouldn’t worry about AE. I haven’t had any problems with them. The search sucks but as long as you know which store you want to buy from then the rest is easy. I’ve only had one faulty item that I had to claim through AE, it was very smooth and painless. For extra protection you can use PayPal, they charge a small fee but then you have added buyer protection with PayPal. I used to use PayPal, but now use a prepaid USD credit card to save a bit on the FX. No problems.

Thanks for this, i didn’t think AE accepted Paypal so this makes it more accessible to me. Just ordered the C01R direct from Sofirn’s website though so don’t need to sign up just yet Smile

Received mine today on the US east coast after shipping on July 4. Fun little light – thanks to Sofirn for producing and the principals here for getting the project together!

I have noticed that my emitter or reflector has a slight flaw that creates a small dark blemish close to the center of the beam. It’s visible on medium in dark rooms or high in brighter rooms. Has anyone else observed this?
