XHP70.2 in a 18650 headlamp, it will be “hot” model. Aux red light is not the first time mentioned here, so I think we will see this feature in the headlamp.
I’m just referring to a headlamp with a more central emitter like the Nitecore HC65 or Acebeam H30.
If you have spot and flood emitter, please use a throwier LED like SFT40 for the spot. The HD20 fails by using xp-l and not xpl hi version for the spot
“Digital” zoom?
Snap on diffuser.
I think we can think about using SFT40 in HD20, as it is bigger with better heat dissipation.
In a headlight in particular we want high cri and good tint. We don’t care as much about higher brightness if it’s low cri and green!
My headlight Priorities:
Cri/tint, UI/ergonomics
High brightness is worthless if it’s ugly
If you want a diffuser, I would prefer the H04F type, but not swivel from bottom as in H04F, but swivel from side, it could be locking on the head, if not in use. (the button would be on the side, as in H04F, so it won't interfere with anything)
For the cooling fins, why not just turn the tube from that wave pattern, to actual heatsink (make the tube thick, and cut fins into it).
It's a headlamp, so the tube is not cover by hand, why not make use of if, and make actually good heatsink, out of it.
And not just one side of the tube, but do it the same length all around.
Since this will be a BLF-Wurkkos in the making..
Why not using a very high CRI of R9080 quadrix E17A and E21A with varying CCT of 2200k, 2700k,3000k up to 6500K. SKV89 has a bunch of these emitters maybe we could get his ideas....
Hello,
I’m a newbie when it comes to flashlights (just bought an FC11) but I thought I would thrown in my 2 cents anyway.
I’m interested in a flashlight with an angled head that I could use for multiple use cases:
- I could clip it to my backpack while hiking, using the detachable pocket clip. In this configuration one of the emitter would be used as a flood, wide angle light (need to see where i’m stepping). Could also be used as headlamp in this use case.
- I could then clip the light to my bike using a third party accessory. In this configuration i would need more throw to see in the distance (using the second emitter in combination with the first)
- As an occasional work lamp I could quickly attach to the headstrap
Like I said I’m a newbie (so please correct me if I’m wrong) but from the above use cases I’m thinking the following features would be a winner for the HD15:
- One emitter (with high CRI) and a lot of throw, similar to the FC11 (or even more throw since there is a second emitter?)
- One wide angle flood beam
- No magnet (not great for hiking use), or make the magnet somewhat removable (even if a little DIY is required). Even better if the tailcap is swappable with the FC11, this way I could have the choice to swap the tailcap for a magnetic one if I need it for work use.
- If the weight of the flashlight allows it, make the top strap on the headstrap removable.
- for the headstrap, use an open o-clip instead of the rubber collars used on the HD20. This looks like it makes it a pain to attach/detach the flashlight to/from the headlamp and also means the pocket clip needs to be removed which is not handy at all. With an open o-clip the pocket clip could stay on, facing forward. Or maybe use the pocket clip to attach the lamp to the headstrap, by sliding it into a sleeve so it would stay horizontal? My point is, either it is a headlamp and nothing else, in this case it would be better as “T” shaped flashlight, or you make it an anglehead (which is what i’m looking for) but it needs to detach/attach easily.
- Similar UI to the FC11, I find it easy to use/remember. A must for me is the hold feature to start in eco mode as well as the ramping mode. Maybe use double click to switch from 1st emitter/2nd emitter/Both. In any case switching between emitters should be easily accessible, way more useful than easy access to turbo mode in my opinion
- I have no use for a red light. Maybe make it an alternate version or have a detachable red filter (not sure if this give acceptable results?)
- Definitely 18650 battery with usb-c charging just like the FC11
- Would be fun to have a short tube option for a 18530 battery, compatible with the FC11 (just like the Sofirn SP40). Especially if that makes it lighter when used as a headlamp and make it possible to get rid of the top strap.
I was outside experimenting with the WK30 last night. Sure wish that was 18650 headlamp.

Voted! CE combination, C. SST20(4000k)-CRI95-TIR(flood) + E. SST20 Red-TIR(flood) seems to be the most useful thing for me 
Voted, thank you!
Voted - AD. I mostly sell to hunters, so a bit of distance on the White & Red would be ideal
Voted. BC for me.
