[Update]Wurkkos dual LEDs 21700 Headlamp design Photos/UI update~

Thank you for this details, we are talking with the factory now to make the UI better. Can’t wait to see the final version and start production.

Long press is very valuable do not waste it for not very often used batt check.
2*click in many lights is turbo. It will be inconvenient.

So
Long press - moonlight
2 * click turbo.
3 * click batt check
4 * click lockout

I think convenient control of two leds is impossible using one button.

The Astrolux HL01 (in 18650 format) weighs even heavier than the Fireflies PL47, so I think that’s one downside of the HL01…
I’ve also gotten the PL47 (Nichia 219B very nice tint), but as Tom E mentions, use it mostly as a flashlight rather than in headlamp format…

I suppose headlamps will really have a weight limit to be useful (and not feel too heavy)…

Good point, agreed. I will check with Wurkkos if they can use this scheme. Спасибо :-)

Strobes sometimes are really useful for locate yourself. But you can make strob with any light just waving or covering the light with your palm

I‘m not against having strobe modes included but I guess the majority here will agree to have them hidden in the UI to prevent accidental activation. Strobe modes are often advertised to drive away / disorientate people or animals assaulting oneself. This has been more or less proven to be quite ineffective. However, to catch someone else’s attention as illustrated above, I agree that SOS and Beacon can be useful.

Yes, please keep them hidden but available.

If you are lucky you will never need SOS, beacon, or strobe as an emergency signal.

But if you are not lucky, it is very valuable to have all three of these features as they each provide a unique capability for very different situations.

It would be helpful to have some hints in the instruction manual so people can better understand when to use these features because while most people know what SOS is for, many have never used a beacon or realize how visible a strobe would be during daylight hours.

Include LOL mode, too. It’s only 1 extra blink.

Intrested please LH351D 5000k for flood and SST20 5000k for throw.

I tried to tweak the UI a little bit, put a bit more emphasis on accessing Moonlight and Turbo mode more easily as well as keeping strobe modes available but hidden. I hope this chart is easy to follow. Any feedback is welcome. THX.

Can the light be locked out with a quick half-twist of the tailcap? If so, just put the battery-check on first-connection, just like my MH20. Why waste a 3click or 4click for that?

My GTmicro, ’mini, Q8, etc., all doubleblink on first connection to power. Just swap that with blinking out the cell voltage instead. Like with my MH20, a quick untwist-then-retwist blinks out the voltage and it’s done. No wasted clickyslots.

Frankly, I wish that would’ve been done on all my doubleblink lights…

I guess so, as I assume the threads are anodized as usual in Sofirn‘s/Wurkkos’s products. I also agree that it would be nice if the battery status is being indicated when the tailcap is tightened. This should be feasible for Sofirn to manage but it depends on their engineer‘s and Mark‘s decision.

HD20 will not blink out the voltage. It is meant to indicate its battery status by a colorful illuminated switch button (as many of Sofirn‘s lights). Personally, I would not want a flashlight to blink out the voltage automatically. There might be certain situations where starting a flashlight needs to be unobtrusive (e.g. during night and you just want to check something by using moonlight mode without waking up your spouse). Most people here will probably know what I mean. :-D

Turbo should be kiked out from cycle low~~med~~>hi.
Changing of flood/throw is difficult and takes a lot of time.

For example I walk using flood light, then I want to look further, and turn on max throw.and than go back to flood.

Combination click+hold can be used for changing light type. Flood>throw>both

thank you for the feedback, we will think about it and adjust the UI better

Thank you for all your efforts. They are greatly appreciated as I have learned from your posts and studied the manuals (even for lights I do not own) which you have provided at:

https://drive.google.com/drive/folders/1e1IWuBMaDQu-YjuigGpMwdUPErdUrMhe

Below are my personal opinions, but please take them as advisement only and make your own final decision, as I am not aware of everything you took into consideration before making your decisions.

"1x click" could be more clearly be stated as "1 click"

"2x click" could be more clearly be stated as "2 clicks"

"3x click" could be more clearly be stated as "3 clicks"

"4x click" could be more clearly be stated as "4 clicks"

"Cycle to standard strobe mode" could be more simply be stated as "Cycle to Strobe mode"

"Cycle to SOS strobe mode" could be more simply be stated as"Cycle to SOS mode"

"Cycle to Beacon strobe mode" could be more simply be stated as"Cycle to Beacon mode"

In the section "When the headlamp is OFF", after using "2x click" to Strobe, SOS, or Beacon mode I am assuming it is "1x click" to "Turn OFF" but this was not clearly stated for those modes. Maybe to be more clear the"1x click" "Turn OFF" line in the chart should be the bottom line of that section and state "1 click" "Turn OFF from any of these modes" and use a similar type wording ("1 click" "Return to previous standard mode from any of these modes") in the "When the headlamp is ON" section. Or have both the original "1x click" line and also a bottom "1x click" line in the chart so it is very clear (but that would be more words which is not always best). But it is OK as is, it just was not as obvious to me as your instructions for the rest of the chart were.

It was not clear if both LEDs are on at full power in Strobe, SOS, and Beacon mode like they are in the Turbo mode.

It would not be a true "Electronic Lockout" if moonlight remains on after a "Long press" while in "4x click" lockout mode. I would not want my headlamp to discharge unexpectedly while in my backpack. I would have it locked out mechanically by un-twisting the tail cap or head but others may not. The mechanical un-twist lockout method should also be mentioned in the manual as some may not know about that.

Your choice for the sequential order of "Strobe, SOS, and Beacon" is the best compromise. Strobe is the mode most people expect first. SOS would be the most important emergency mode. Beacon is the mode probably used the most but the order you have chosen is easy to remember and what most people would probably expect.

"Click" or "Long Press" to change brightness levels is the most difficult decision as there are pros and cons for each method. With a flashlight I can live with either but with a headlamp I would probably prefer "Click" to change brightness levels because (in the most difficult situations where I may be using a headlamp) I have an easier time getting to the correct level I want when doing it this way while wearing a headlamp which is moving around on my head while I "Click" or "Long Press". But if you use "Click" for brightness level changes then you must also use "Long Press" for OFF. It is probably best to choose the most common method as you have done because that is what most people expect and would want.

I do not know the specific mechanism as to how the proposed "3x click" "Check battery function" will operate (maybe different colors and/or blink patterns on the switch's internal LEDs to indicate the voltage) but In addition to that I would also like to have a low voltage battery warning that occurs automatically while the headlamp is on and is also very noticeable while I am wearing the headlamp on my head (as I will not be able to see the switch). Maybe something like a blink sequence that occurs occasionally as low voltage is approached and then more frequently and finally almost continuously right before the headlamp light cuts out due to low voltage (and I hope this headlamp will have true built-in low voltage protection besides just a low voltage warning).

I do like lights that have a way to keep the switch's internal LED illuminated while the light is off because it helps me find the light in the dark. But please provide an option to turn this feature on and off and do not make it too bright or breathing.

I also agree with forum member AEDe that Turbo should not be in the standard mode cycle (unless is it sustainable for more than a few minutes) and agree with AEDe that it would be innovative to have a more convenient way to very easily change between "Spotlight and Floodlight on" "Spotlight only", or "Floodlight only".

Oh I like this alot. Ive been waiting for a new headlamp and this one hits all the marks so far.

I didnt read the whole thread, but was the flood emitter a high CRI SST20?

Thank you AEDe and roostre for your valuable feedback. I take your suggestions seriously as you probably have much more experience with headlamps than I do. AEDe for instance, you provided us with some great on-site pictures using your Panda headlamp some months ago. So, to make a long story short: I have tried to simplify the UI according to your input as well as to make HD20 more convenient to operate.

I had the idea to include an "off mode" for each LED in the standard mode order. The benefit is that we can spare the triple click to adjust between spotlight, floodlight or both. Each LED can be accessed and controlled easily in its brightness by two commands: Hold or Click'n Hold. What do you guys think of that? Would that be convenient and easy to memorize at the same time without losing too much functionality that a dual emitter light can provide?

I also agree that an accidentally triggered moonlight from lockout is not what we want. So, I would change that to a temporary or momentary moonlight as long as someone keeps the button pressed.

@Mark (Wurkkos):

I hope you and Sofirn will be able to wait things out until we have a decent UI that most customers will feel happy with. I think we are very close to saying "Yep, that's what we want." :-) Without meaning to be nitpicking I think that some former lights were launched a bit too early in the first place and fortunately became much better afterwards due to reasonable UI changes, e.g. Wurkkos FC11. I would like HD20 to start with a great UI from the very beginning.

Would sure like to see this UI in an FSM implementation. Should not be difficult to do, being so close to how Anduril works.

For the UI why not use anduril? It has a verry nice way of handeling 2 led channels, and would be a selling point to everyone familiar with it. putting anduril on it would probably tip me personally into buying it.

This UI is looking pretty fantastic so far.

My concern is that if both LEDs are cycled to the “Off” mode, will the light itself technically still be on? How will that be handled in mode memory - for example will turning it “On” not activate either emitter then?
