Sofirn C01R deep red [sold out, discontinued]

good observation

there are several factors in play
1st, technically, the reading on my meter, when measuring Red, should be increased by 62%. I did not do that, as it adds complexity that I did not want to discuss too soon. Now that you bring it up, consider 42 lumens of red is roughtly equivalent to 68 lumens of white. That accounts for your correct observation that red looks brighter than the lumens straight off my meter calibrated for white light.

Another factor is the size of the head. My meter underestimates the output of small sofirn AAA…

these variables are part of the complexity, that a deeper study of Red light will encompass.
These two lights have almost the same output, on my meter… both are on maximum…

(again bear in mind my meter underestimates the small lights, but in this case, both are the same size… for example, the C01S is actually supposed to be making 100 lumens on an intergrating tube)… I think the red does look brighter than the C01S, despite what the meter reading would suggest.

Since I am experimenting with Red Light Therapy on my eyes, for me the important thing is to not use Red that is more than 40% the brightness of noonday sun. I believe staying below 20 lumens of red on my meter, unadjusted for spectrum differences, is similar to the level used in the vision study. So I use medium on my C01R.

Marc E great photos and info, thanks

great option, thanks for sharing info and photos

I do think a pebbled optic, with a nice diffused beam, would be a nice option… depends what we use the light for. Certainly the focused red beam works very well for seeing across a room, while the diffused beam is more suited for close use, at arms length.

choices vary by application…

me too!
Instant cult classic here :+1:

and I like the stock beam too… because the hotspot is wider than on my Tool/Maratac aaa reflector lights

Will there be another preorder discount, Lux?

I will do my best asking Barry for a nice BLF discount to preorder C01R (with SST20-DR). Not sure though if we can expect a bargain price of $ 7.99 plus shipping again. I hope Sofirn will also be able to supply a microlensed/pebbled optic suitable for C01R. Awaiting news from Barry anytime soon.

Not sure if I speak for anyone but myself, but I’d love to have two (or more) optic choices than a discount on an already well priced light. :smiley:

Imagine if Sofirn offered a combo accessory pack of 2-3 additional optics for a reasonable price. Of course these optics could possibly fit every C01S/R/??? including the hopefully upcoming E21A version, so it would be quite versatile and not limited to the R. Emisar does this with one alternative optic you can add to the D4V2 upon purchase and Convoy has a 5 pack of different optics you can buy for the S2+.

Wouldn’t that kind of accessory pack completely set the C01S apart from the competition? Don’t get me wrong, even ONE extra pebble optic along with the flashlight would be wonderful.

How much would be nice an Headlamp Red version or 2000k E21A
with programmable moon mode
like E02H

I thought I had ordered one also, but when I received it today,I saw that it is the C01S with a white led in it.Of course,the aluminium was painted red… :person_facepalming:
I don’t understand who’s the fault is,so,I keep it for a keychain light,waiting the new red led light with the SST led.

Where did you order from Theodore41? Sofirn does offer the C01S in red anodization, too.

However, everyone with a C01R should also have a C01S and vice versa. :-))

By the end of september I hope Barry or I will be able to post a new update on C01R using SST20-DR. Stay tuned...

I ordered from a shop in Aliexpress.The name is Beamax lighting store.

I believe Beamax is also Sofirn’s “other” store, because when I tried ordering something from Beamax, and was asking some questions, the same person replied to my inquiry as in Sofirn’s AliExpress store. :slight_smile:

For anyone that missed out on the C01R, it appears to be in stock at Amazon. Maybe that’s why all the official store inventory disappeared?
Sofirn C01R at Amazon US

Nice!!
Any group code?

Well indeed it is, thanks for the heads up!!

I’m not sure if that applies on Amazon? In any case, I don’t have any codes. But for what it’s worth, the price on Sofirn Official was $9-$10 iirc. Only $2 more and you get it in less than a week.

Wish for C01R SST20 670nm

Actually, there is no true 670nm chromaticity bin of Luminus's SST20-DR. The good news is that Sofirn told me they were able to get some with a standard wavelength of 660nm peaking up to 670nm. That should be something in that yellow highlighted bins.

What is the difference between the today existing light and the one with the SST led?

Even deeper red, and SST20 presumably fits the optics better.

First of all, I do not expect any huge differences between those LEDs. They will probably be barely visible. I suppose you may notice a slightly better beam pattern and a bit more brightness on high mode. XP-E2 photo red has a smaller die area than SST20-DR, so the hotspot of the new version should look a bit wider.

I hope to receiving some news from Barry after the national holiday.

Amen… :slight_smile:

Barry was so kind to send me a quick whitewall-shot from his smartphone camera.

Sofirn C01R XP-E2 PR 660nm (series version)

Comments based upon some feedback from Barry:

  • actual perception of deep red color is more intense than indicated here
  • C01R SST20-DR is quite similar in maximum brightness - although actual brightness may differ but needs to be measured using a lux meter
  • hotspot beam shape/profile of C01R SST20-DR is yet to be reviewed in detail as any artifacts cannot be assessed on that picture - for now it looks quite similar to XP-E2 PR
  • production of C01 using the 670nm 5mm emitter may be revoked as the beam shows significant distortions - final decision is not made yet
