I am absolutely interested in such a light (esp. useful for astrophotography, where red doesn’t inflict with night vision and the brightness should not be high, and the light is small enough to hold it with the mouth as headlamps are often uncomfortable and interferer with telescope viewing)
I am also very interested in the XP-G3 Version as it is deep red. I would pay the higher price (as 625nm vs. 660nm do make a difference)
Yes, I would also prefer some darker red with a matte finish as red is used for C01S already. Let's see what Sofirn can do about it. Another option could be "no ano" clear aluminum but I think this would interfere too much with the C01S "BLF edition".
Interfere? It would likely be the other way around. The C01S “BLF edition” is rarely available, it may have to do with Sofirn ordering scarce and small batches of un-anodized C01S bodies. If we give 'em more incentive to order un-anodized bodies we would have both red and 4000K versions more readily available.
Interesting point Barkuti. You could be right about that since Sofirn is waiting for their C01S stock to deplete, so that the next batch can be offered with most wanted features (low-high mode order, for instance). I don't know what they are up to next but this could be a great opportunity for joint activities, i.e. reconsider the entire C01S production schedule and integrate the red so called C01R into the whole sales strategy. I'll check with them tomorrow again.
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).
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.
