Good to be here, and sorry for ambushing you with so many letters … .

I believe it’s because his first post on BLF was via PM.
A warm welcome @Lumenix to BLF!

What’s what happens when people have no point and direction. All in 1 and gets 0 at the end.
What about this light seems unrealistic to you ?. I just described it stupidly detailled.
Hard to disagree. You are welcome.
BTW how much it will weight? … and why you prefer vertical T shape instead of horizontal?
It would probably weight a bit more than the “D25”, since having many more components inside, but for all normal activities, it would still be perfectly useable. For more demanding sports that involve extreme climate, like climbing, mountaineering or trailrunning, there should be a dedicated design, possibly optical parts only, with an external battery that can be body-worn and connected via a magnetic cable.
It’s actually horizontal-t-shape, and I found that to be more stable on the head due to the lamp usually getting angled down 30-45 degrees for optimal illumination. A vertical-t-shape like the “Sofirn HS20” would then stand out quite far. Also it is really unergonomic when handheld.

There is a lot models of “Allin1foreveryone” headlamps. Like i asked before whats the purpose of new light?
Have you consider add variable tint?
Looks chunky but good.
Swap the red LEDs out for 1800K or something and I’d buy something similar. The low build quality of the D25 lights puts me off, photos make them look less nice than e.g. convoy headlamps.
Oh and just to add, Cree claims the XE-G LED’s offer the most colour options in a single footprint format. They’re also rated to 3A, double the XQ-E… The reason nobody seems to use them is that they have a weird footprint.
I am with you, there are already quite a few 18650-headlamps with more than one channel out there. And it surprised me that after the apperance of the “HS41” and “HS42”, another headlamp is to be designed.
What I miss with all those options is modularity, for all the enthusiasts among us, and i miss multicannel-“Andùril 2” since so many non-standard UI’s appeared. It should also be a bit more affordable than those options from Acebeam, Skilhunt or Wurkkos.
But yeah, could have been done right from the beginning.
In a configuration with daylight-white low-CRI-main-emitters and an ultra-warmwhite second channel, it would be kind of able to tint-ramp with “Andùril 2”, but I think only the very enthusiastic will need real tint-ramping on a headlight, which the “Emisar D4” is already for.
I would absolutely love to see the “XE-G”-emitters make an entry in the flashlight-market, and the first thing I would build would be a 40W full-cyan “Emisar-D1”.
I suggested the “XQ-E”'s for cost reasons and footprint-compatibility only.

Would all be possible. But you would need a 2-channel buck-driver, and a 3rd linear channel if there’s red light aswell, which wouldn’t be very affordable anymore. Or do you know a more compact and easy driver-solution ?.
2 channel. Buck is good for red. But yes its getting more complex. A year latter Nitecore H68 made it and patented too 
Here is my input on your questions Sofirn:
- I prefer 18650, due to the extended capacity/runtime. For me the 18650 is the optimal combination for a headlamp, in terms of enough capacity/runtime, without getting to heavy and/or big. An optional 18350 tube would be a nice addition though!
- For close up work I think I prefer 4000K, but I could also live with a good 5000K LED. For a (white) ‘thrower’ LED it doesn’t matter all that much to me.
- T-shape or L-shape isn’t all that important to me for a headlamp, but I could imagine that for people that also want to use the light without the headband, the L-shape might be a bit more convenient. (Especially if you can choose/switch between an 18350 and 18650 battery tube!)
- I could imagine that leaving the pocket clip on in the headband could be usefull, if you can find a way to make that easily possible, but for me it’s not so important; I use a headlamp almost only with the headband and store the pocket clip in a fixed place. In the rare occasion that I might need to use it with the pocket clip, I just switch them out.
- The arrangement of the LED’s isn’t all that important to me, just as long as the right reflector or TIR is used for each LED; A good wide (beaded) TIR for the wide angle LED, a good narrow TIR or reflector for the spot LED and also a good wide/floody optic for the red LED, although that one isn’t all that important to me.
All in all I think I just prefer a versatile as possible headlamp; a choice between 18350 or 18650 batteries and a good UI, to switch between several options of flood and throw (or a combination of both).
I changed my reply from 18650 to 14500 and AA.
I don’t need the additional runtime and would prefer lighter.

Agree, there are plenty 18xx lamps.
The design that Lumenix have posted would be nice for Ni-Mh/14500
I considered it, but integrating all those features in a 14500-host would be extremely difficult, or come with barely any weightsavings compared to using a 16340-cell with an adapter.
What do you guys think of a design with an external battery on a magnetic cable ?. That could solve the weight-issue once and for all.
