Considering, what thoughts are shared recently, I would vote for some details as below (and would suggest name alternatives as well):
- Factory emitter dedome would be awesome (add a T letter suffix to the name, if the emitter is dedomed)
- If emitter is not dedomed, I'd prefer these tints: 80CRI 4500K/5000K or 90CRI 4500K/5000K/5700K
- If dedomed, original tint of the emitter may change (it is a guess, not experience, would need some backup), so probably a cooler white emitter would be better then
Edit: factory dedome does not worth it.
SP70-70:
- single XHP70.2
- dual 26650 with 21700 adapters (I hope, this would be a great opportunity for using cells like Samsung 21700-40T)
- reflector diameter would be best in 87-100 mm range
- 12A max current on turbo, 8A as top level of ramping
SP70-50:
- same CCT and CRI, same battery configuration, same reflector as above, but single XHP50.2 instead
- as I remember, if properly heatsinked, that emitter would be capable of fairly high candelas especially, if dedomed
- proportionally, a little bit harder driven, 9A max current on turbo, 6A as top level of ramping
- less output, but more runtime for the same candela numbers
SP70-35F:
- same CCT and CRI, same battery configuration
- this could be the one, which Sofirn has mentioned with multiple XHP35 HD emitter
- this would need a shorter, but larger diameter head design to keep the reflectors for each emitters as separate, as possible
I think, your thoughts about the UI are much preferable.
I would just add these:
- in Group 1, after activating strobe, press and hold could loop additional special modes (1 change per completed 1 second while holding the press, just like changing normal output levels), as someone here voted for additional special modes - I think, that would not be a bad idea, if they are hidden enough
(fast strobe /10Hz or 18Hz/ would be the entry point, followed by SOS signal, 0.5Hz (once per 2s) beacon and 0.2Hz (once per 5s) beacon)
- I'd chose triple click in Group 2 to enter to/exit from momentary on/off mode with the last used output setting. That would be sort of awesome, I think ;)
Edit: Yes, probably blinky modes won't be used too frequently (I accept Sofirn's opinion on this). A momentary on/off could be still handy, though.
Regarding switches, I would choose single side switch or dual side switch. Please, no tail switch for me.
Very much agreed.
P.S.: For the current flashlight development, please ignore a few of my previous posts in this thread, as they were meant for another model, which I would happy to see manufactured by Sofirn.
