Not on a deep-red light, though.
It’s nowhere near as visible as a more orangey red (“Portland orange”, “traffic-red”), so the purpose of the light (red-light stimulation, not ruining night-vision, etc.) is counter to the idea of bright and visible, like for a warning-beacon.
It’s like using a MT-09R to roast marshmallows. It can be done, but it’s hardly the most efficient way to do it.
Interesting and fair point. I’m kinda new here on the forum and I certainly don’t know a lot about red tints 
There is a use case for a strobe as some publications show better results with pulses in the 1-10 Hz range (50% duty cycle is a common value), but the specific frequencies used need a deeper reading.
I’m given to understand that part of this project was ostensibly to have a light with a deep-red/photo-red/far-red emitter, vs The Usual Red, for the above reasons.
So… gotta stick with the spirit of the project.
And sometimes simplicity is best. Eg, fairly recently (ie, this past year) I got a few AAA lights: Thrunite, Glaree, Skilhunt, Oilight, etc. Most have multiple modes, except the Skilhunt.
Guess what? The one I use the most is the Skilhunt. When I just need Some Light, it’s right there, 100lemons worth, and it’s on and off.
If I want half-a-lemon worth of light, I can always grab one of my other lights off the table, then ramp up or whatever as needed.
I suppose someone might want a photo-red candle or sunset or strobe and also want Andouille in a light with that emitter to get it, but WHY??
Important update [10/23/2020]:
Sofirn informed me they will work on a new AA flashlight design, replacing the SP10S design. Consequently, SP10R will be shifted onto the new AA schedule.
Due to large-scale launches of other new models, SP10R will need to be postponed until further notice. Please stay tuned for any future updates.
Will we be able to give feedback on the new AA flashlight design?
Yes sure. But Sofirn did not disclose their new AA design yet.
I will also keep on collecting your interest here.
Add me to the interest list - ty.
I just received a Kdlitker P60 host with a 660mn triple P60 drop-in. It has 4 levels (moonlight/very low, low, medium, and high), and a hidden (double-click) 8hz strobe. It’s listed as 800 lumens, and though I have no way to measure sure how accurate it is, the output appears bright enough to be in the neighborhood. 620mn and 730mn are also available, as well as blue, green, and amber. As well as a wide variety of Cree, Nichia, and Luminus white in various tints. KDLITKER Photo Red 660nm
Here’s a vid of the strobe mode in action, compared to the Class 1 amber strobes (same brightness as emergency vehicles, tow trucks, ect.) on my explorer:
As is common with many phone cameras, the night vid is a bit dimmer than in real world. For reference, the porch light is a 60 watt equivalent LED bulb.
Hmm, 8Hz is a bit too fast for what I would like to use it for but thanks for sharing
interested!
my suggestions:
continuous 3 levels (sustainable) + turbo (non-sustainable/too hot)
around 10Hz strobe apparently had best healing effect iirc from the 670nm thread
reasonable runtime and output from 1.2V AA NiMH
prevents draining NiMH below 0.9V either by switching off or first lowering output at 1.0V, then switching off at 0.9V
lockout function, if side switch
maybe also a mode-order-change like C01R has
flood beam like C01R
as always, waterproof (I wash my lights and hands with soap after I was outside / if hands got dirty)
so basically the SP10, in 660nm, with a floody beam and 10Hz strobe
Interested
I’ll take 2 more, so 3 in total
interested
any news on this one?
I’d love to get this one after Sofirn finished their SP10S Andruil version!
Interested in two (2).
Thank you.
Interested
Interested.
By the way, how about using far red LED (720-740 nm) like Cree XPEBFR ?
