Sofirn C01R deep red [sold out, discontinued]

Interested

A deep red matte finish sounds amazing. :money_mouth_face: Please bump me up to three.

TLF member oOFOXOo from Austria did a great job and put a new tint look onto the illustration, see picture in the OP. This is „Crimson Red“ (RAL color code 030 30 40).

Interested!

I can even see 730nm (which is called ‘Far red’), but my eye sensitivity is noticeably worse there (but I can still pick up that distinct deep red color very easily - and it is still much-much better than looking into 780nm near-IR LEDs). But, when I compare it to an ordinary 625nm red, the latter just looks like a very deep orange (or ‘light red’).

660nm could be a sweet spot, as the human eye still has fairly good sensitivity to that - despite it is a ‘redder’ red.

Speaking about special light sources, there are even less ‘lava’ or ‘ultra warm white’ flashlights around.

But there could be a potential, I mean, the BLF community already accessed and tested a few very good emitters:
Luminus Xnova Cube (1800K, 90CRI)
Nichia E21A (which has 2000K CCT variant with CRI 95 and R9 above 90)

For some applications, I could even imagine using a 1300K to 1600K CCT emitter, but unfortunately I haven’t see a good one yet. The trick in having a non-monochrome (but still very ‘dark adapted eye friendly’) light source, that one still can perceive colors (just blue light is making up a very tiny part of the emitted spectrum, and cyan/green light is still rather slim), and it covers most of the situations, where previously 625nm red lights were used, but it is easier to see with.

So, if I think about alternative C01 versions (just hypothetically, based on my needs/preferences/wishes), I would be in for C01L (‘Lava’), and C01DR (‘Deep red’).

By the way, I do know, that doing negotiations with flashlight manufacturers is a meticulous task, so I thank you for your efforts.

Muito obrigado, Thomas!
Danke sehr!! :wink:

Interested, prefer Deep Red, but would buy a “normal” red.

Count me in for one

I think it should be noted that the definitions of the lumens and lux already take into account the varying sensitivity of the human eye to different wavelengths. In contrast, the related terms radiant flux and irradiance do not take that into account.

So 100 lumens of 660nm deep red should appear the same intensity as 100 lumens of 625nm red.

The difference in practice is you get fewer lumens for the same power.

So while Cree rates the red XP-E2 for up to 80 lumens at 350mA, based on the function that approximates the sensitivity of the human eye, the photo red XP-E2 probably only puts out about 15 lumens (Cree only rates it in mW, not lumens).

Interested, in for 2

Also interested in one.

I’m interested in red and deep red.

Add 1 for me please
Cheers

One more for me plz, total of 2 :smiley:

This is an acceptable trade-off for me. It would make it appear approximately half as bright, which is noticeable, but this was never meant to be a powerful red flooder, just a dedicated red flashlight for use in low light conditions.

Perhaps offering the option of XP-E2 Red and XP-E2 Photo Red would be easier for Sofirn? Unlike XP-G3, these 2 emitters seem to be very similar. No additional effort may be needed to offer both as an option, it would probably be a straightforward emitter swap.

I’m also interested in 2.
Thanks!

84 pcs accounted for already. :+1:
Only 116 pcs left to make it happen. :wink:
