[Postponed] Sofirn SP10R - deep red AA/14500 EDC

Interested.

Like this?

Well, this would mean a complete new host and reflector design which is probably too much an effort. However, I will keep your idea in mind as it's interesting.

Alternatively, you could try looking for a flashlight like EagleTac D25LC2 Color using the (rather old) XM-L Color LED, with RGBW tints in one LED.

I'm not sure if a red SP40 would get a lot of interest. But Wurkkos's HD20 with dual emitter layout might be a good host for using both white and red light in one headlamp.

That's the right attitude! :-D Buying just another one exclusively for your wife might let her forget any objections. ;-)

I am afraid there's not much to compare this LED with. Cree's XP-E2 photo red is (presumably) less powerful and smaller in die size. Luminus has its direct competitor, SST10-DR with similar characteristics. My hopes are that SST20-DR will sustain more current, have more output at slightly larger dome size and will fit better to the SP10S driver supporting li-ion batteries.

Interested

In for two :slight_smile:

Interested. I hope if this project does go through some of its improvements can trickle over to the SP10S.

SOS in a red-only AA light? Really? :person_facepalming:

Pass.

The far red light is only medically useful for people over 40 years old, according to the published research.

I’m interested, but whether or not I purchase one will depend on the UI.

I think the draft UI looks similar to the Olight Baton UI, which is one of my favourites, but I do have some concerns:

  1. A single click from turbo returning to the previous mode rather than off is inconsistent. I think a single click from on should always switch the light off, regardless of mode. I suggest using a double-clicl from turbo to return to the previous mode.
  2. I think it should be possible to progress to the next mode from both firefly and turbo by holding the button. I think the C8F locks you into moonlight when you access it via the hold from off shortcut and it’s really annoying.
  3. I would really prefer not to have an SOS mode. At least with a red light I think a strobe or beacon would be much more useful, but I could do without those too.

What's the matter with SOS in a red light? Actually, SOS and maybe Beacon are the only modes that make sense to me. But, it's not up to me and as stated in the OP this is a draft UI, so suggestions are always appreciated.

That would be inconsistent with any of the other Sofirn flashlight UIs. One click from Turbo always gets you back to the previous (standard) mode, if I recall correctly. So far, I did not receive or see any significant feedback that this behaviour should really be changed. I remember that we had a brief discussion about this on Wurkkos's new HD20 headlamp thread. If the majority here wants this to be changed, I will be glad to discuss it with Sofirn.

Agreed, thanks. I will update the draft UI.

I understand that the entire strobe modes are open for discussion. IMHO, I could live without any strobe modes but it seems I underestimated the demand for these modes. So, maybe let's just use the classic option of all three modes (Buzzing Strobe - SOS - Beacon).

Anyway, OP is updated accordingly.

Fortunately, I have no use case for another deep red light. Might be interested nontheless if this one has much more power.

Depends on what you expect as "much more". ;-) If you want it reeeaaally bright and deep red, then Hank's Noctigon KR4 or Emisar D4v2 with 4x SST20-DR might be the right thing.

Nah, since I have no real use, it must be inexpensive :wink: .

Much more power = notably brighter. I know the battery format is very limiting.

Actually, I was rather impressed with the maximum brightness of XP-E2 photo red in C01R. Let's see what Sofirn can squeeze out of an SST20-DR using the SP10S driver (with some adjustments, of course).

The firefly in my SP10S is absurdly low. But I guess that the modes will be made again for this version :slight_smile:

It’s just retarded to stick SOS into every light ever made, even AA- and AAA lights. It’s like walking around with a parachute strapped to your back all the time, because “you never know when you might need it”. :confounded:

Interested for the LED :slight_smile:

I doubt I’d use SOS and strobe modes.

Different blink intervals and intensities may be useful when using this red light with a diffuser as a Rear Light on a bicycle. Too complicated?

I would one with Ramping UI and E21A

Not even remotely. I'm open for all kinds of suggestions in order to get SP10R as good as it gets. Can you please elaborate what kind of blink intervalls were useful?

It seems there are two opinions here: Those who more or less want to get rid of any strobe modes and those who have very precise ideas what strobe modes are good for a (deep red) EDC light. One thing in life is for sure: You can't please everyone. For now, I will leave things as they were ever since, i.e. triple click will get you those three classic strobes ("angry buzz", S-O-S and Beacon mode). I look forward to seeing further feedback.

Agreed but unfortunately, that's not gonna happen in this thread. ;-)
