[Discussion] VEZERLEZER Tail Clicky Flashlight User Interface Discussion

Not sure if other members will agree with you.

Do you agree with Quadrupel about the switch, please comment below to let us know. Thanks.

How will this be different than all the other dual-switch lights available right now? Wowtac, Wurkkos, Sofirn, Thrunite, and many other brands have already saturated the market with $30-50 lights just like this, with a mechanical forward clicky switch on the tail for on/off, an electronic switch on the side for changing modes, and USB recharging. What features do you plan to add that will make this light competitive with what’s already available?

I think offering multiple, popular LED options would be a great start. Perhaps you could offer SFT40 for users who want maximum brightness and throw, and also offer Nichia 519A (de-domed) for users who want nice color temperature, tint (DUV), and CRI.

Offering this light at a low price point with a switching driver would be compelling too. The offerings from those other companies I mentioned mostly use low-efficiency direct drive.

The inclusion of a shortcut to moonlight (hold side switch while pressing tail switch) is a great idea. I had an Olight M1X years ago that had that feature. It’s very useful and none of the competitive options on the market currently have that feature.

The UI looks in line with other lights on the market, but I think the shortcut to Turbo from the tailswitch is a great idea!
I’m interested to see how you approach this, since lights that do this tend to have an e-switch/driver in the tail - but that’d require a signal tube if you had another e-switch in the head.
If you can make this work with a mechanical tailswitch, I think that’d give us the best of both worlds (0 parasitic drain and some shortcuts still available).

I don’t have much of an opinion on Strobe, but I know security employees sometimes like that.
If it can be hidden by switching between modes and it makes the light more marketable, then I’m all for it.

Now it is quite difficult to make innovation in flashlight, so user experience is the point we pay most attention to, and that is why we here to ask suggestion. Common flashlight users they don’t use flashlight as members here do, if you are quite satisfied with the user interface then, it should be okay for the common users.

Regards the emitter, SFT40 and Nichia 519A are both nice, this suggestion will inspire us when developing this flashlight.

Fact is a fact, mechanical switch increasing resistance in circuit. Try to make quality and sell it cheap. Copy Zebralight host and electronics, load Anduril and sell it for half price! :wink:

What do you like about Zebralight host and elctronics?

Yes and no. A forward clicky allows for momentary light, which is a typical ‘tactical’ feature. A reverse clicky would be nonsense along with a side switch.

An EDC light should not have a mechanical button imo.

A good FC+sideswitch UI includes switching the light off with the side switch. So:

FC on:

Click - on (memory) and off
Long press from off - Moon
Double click - switch between max and last mode
Hold - cycle through modes

However, lights with similar features are ubiquitious. Why should I buy your light? :slight_smile:

Invest in developing an efficient driver and take some more money for the expensive parts instead of competing with Sofirn/Wurkkos. That said, your temperature regulation algorithm is not bad. Response is a little slow, but better than the regulation (if there’s any) of many other lights. Congrats for this.

Think about energy management. You lights should not just go out. Calculate 10 to 20 minutes on low at the end of battery life.

Carefully design a clip. The light should point downwards, the clip should be fixed with screws.

Let it have a massive shelf to take some heat, a couple of mm length more is not important.

Forget pressing the last lumen out of it by using cw emitters. Choose SST40 in 5700 or, even better, 5000K.

Get yourself a TrustFire T11R and be better than this light. It is hard to beat, but if you manage to do it, you can sell it.

BTW, the collar-less switch is good. FC should always be freely accessible.

You’re welcome.

What’s not to like?

I disagree. Screws hold the clip firmly, but they also lock the clip down to a single position. Some users like to be able to adjust the clip’s position to align with the side switch, to be opposite the side switch, or anywhere in-between.

The best solution for a clip that can be adjusted but also stays firmly in place is a collar-style clip, paired with un-anodized tail threads. The tailcap can be loosened for clip adjustments, then tightened down to hold the clip just as firmly as screws.

It’s also difficult to have precise enough machining tolerances that a screw-in clip would always line up the same way on different samples. The only reason Zebralight can get away with it is that the clip attaches to the unibody head/tube.

In a crowded marketplace a small but distinct difference might ignite interest and spell success. I was thinking that an instant on feature is very different, none of the dozens I own has anything like it. From vertical to horizontal it switches on, like the light on my Casio watch. Give a little shake and it turns on. Gimmick? Gimmick is a nasty word for interesting.

For the last few years I carry what I think is the best duty light. Physical tail switch for strictly on/off and momentary use with pressure. Side switch for mode selection only with double tap for turbo and double tap again for strobe. Modes are moonlight, low, medium, high. I just retired after 27 years in law enforcement, physical tail switches on a duty belt light is very important. No accidental switching on, no parasitic drain, instant one handed finding and use. Really needs to stay in one mode only while working the tail switch. Scrolling through the modes while working traffic, building searches is not a good thing. I’ve never used S.O.S. but have used strobe to guide ambulances over, get peoples attention or signal where I’m at or where to look. In light rich areas like parking lots, streets and shopping centers strobe set you apart from other lights.

So I’m going to respectfully disagree with a few here and state that Physical tail switches are still important in tool lights.

Very interesting, imagine you raise a flashlight and then it turns on automatically.

You are right, physical tail switches features no accidental switching on, and no parasitic drain, instant one handed finding and use.

Accidental turn on depends on host construction not the button and with E-switch you can lock with soft. “Parasitic”(IC standby) drain is so low that will take years to deplete battery, same as self batt discharge.

People who actually need to use strobe like single click access to strobe, not fumbling through a user interface to find the hidden strobe as per most flashlight UIs at the moment.

Vezerlezer appears to be suggesting the use of different mode groups in the UI. Perhaps one group could be basic EDC style with a few different brightness levels and no blinkies. Then another group could be just Turbo and Strobe where they are memorized, then light painters could use that second mode group with strobe memorized.

- Tolerances are sometimes off. Glass may rattle. Switch cover may be overly squishy.

- Sometimes there’s high parasitic drain.

- User interface takes a bit of getting used to and is buggy. Both my HI and LE randomly get “stuck” on and the button becomes unresponsive.

  • A few customers allegedly received low CRI emitters in their SC64c LE when they should’ve been high CRI.

That said, I love how small the LE is and moonlight mode. The efficiency is nice.

This seems to be what they plan, a user interface that keeps everyone happy.

We hope so.

It’s hard if not impossible to design a UI that can please everyone. Ask 10 people for opinions on a UI and you’ll get 23 answers.

If you want to design a “tactical” or “duty” light, design the light with a UI geared towards that.

If you want an “EDC” light, design a UI geared towards that.

Nb: “UI” means both the software (“how many clicks”) and the hardware (side- and tailswitches).

A good compromise is the Sofirn C8F, which has both side-/tailswitch. The tailswitch is simple for hard on/off (plus momentary), and the sideswitch is only for mode-changes.

If you include a “standby” mode, you can have the tailswitch on but the light off, and be able to press’n’hold for moonlight, 2click for turbo, etc.
