Nice design. What’s the length? And does it comes with pocket clip?
Interested.
I strongly suspect it’s 160g for just the light + cell. No 21700 light I know of gets anywhere close to 120g loaded with that size of cell. For that matter 160g isn’t even bad for a light of with that cell format, but it’s way past suboptimal for a headlamp IMHO.
That means something like 130g when using an 18650 cell, so not as bad in that case assuming it has dual springs and/or a cell spacer included to operate with them.
Neat design! Can you run both flood and spot at the same time? If so, why not aim for making both LEDs the same tint? (5000-5700k)
and output? looks interesting
1600lm max for throw light and 600lm max for floodlight

Yes, both flood and spot could be turn on at the same time, and adjust different modes when both turn on

the length is 12.1cm and yes it comes with a pocket clip
6500K - please forget about such led! 4000-5000K and the same CCT for both led.
21700 why? 21700 good for EDC , pocket-roket… but not for 1000lm range L-shaped hadlamp. with 18650 you can get good weight and dimensions it is one of the most important things for headlamp!
Don’t try to make ‘laser’ from throw. Pay attention to shape of spot.Design looks good but I not sure that it is convenient to use headlamp with big center of mass offset.
yes, that is the point about size and weight when we decide to use a 21700, for a input and output 21700 with more power and runtime, here is beam for test sample, 4000k tint floodlight and 6000k spot
6000k spot beam
4000k floodlight beam on and off
Stuff like this makes me wish that Wurkkos had a website. Though if someone from Wurkkos does read this: I know you are close with Sofirn but please don’t use whoever did Sofirn’s website.
Yes, thank you, we will do a own website soon, till now our products are not rich enough
Looks like a good flood and spot! Definitely need to go for the same tint though for when both are used.
Yep, looks a bit heavy for a headlamp, but I’d certainly use it as a right-angle flashlight.
As mentioned, it’s best to have both flood/throw match. You don’t want something lit up blue at a distance, then be lit yellower as you get closer.
And yes yes yes to that mount. I hate plastic C-clip holders, because they can snap, and the light often pulls out way too easily.
Rubber-loop mounts are the best. Easy to use, the light doesn’t fall out accidentally, and stays in place with the rubbery grip vs hard slippery plastic.
I’m scared to think about the UI, though. :laughing:
will update the UI soon
Please no 6000K for throw!
Stick with 5000K and below. High color temperatures for throw are useless when there is a lot of dust or moisture in the air. Please HiCri for the flood. I’d say do a 5000K XPL Hi or SST for Throw and a 4000K Nichia or Samsung for the flood.
This is look'n pretty good. The UI and switch (switch is really part of the UI) are very important to me - makes all the difference and so often it's done wrong.

Optics are good :+1:
But of course warmer tint for throw needed.
Similar to Nitecore H35. Made like EDC- headlamp, but L shape uncomfortable for use as EDC and too heavy as headlamp
Being 40-50g lighter with 18650 and 1-1.5cm shorter it would be much interesting as headlamp. For 2000lm output(in turbo) not necessary to use 21700. Maximum stable output for such host about 600 lm (with hicri flood , and neutral throw) so it is at least 2h runtime.
Or maybe more interesting… 18650 battery, buck -boost driver , 3500K Hi-cri LED with 60 degree main optic and 30 degree small optic with a deep red LED
hmm. may consider use both 5000k for main light and floodlight
Why not several 26650’s on your head?
Does anyone ever used the head lamps they design?

My vote would be 4000K for flood though.
For weight reduction, adding more finning, and finer finning would help with the heat, as well as reduce weight. I would think that tube design results in excessive weight as well - might consider more cut-in's to reduce weight with the tube. I think the overall design is good - it can be done with a 21700. An example of a very lightweight light is the Skilhunt M200 - I weighed it at 44.6 grams, about the same as an 18650 cell. It has a very thin battery tube wall, thin head with some decent finning in the head.
