That’s a great idea. At the driver end you’d probably want something quite soft so it can deform around any smd components on the driver PCB and spread the impact. Some kind of dense foam maybe? I’ve got a convoy s11 that changes mode every time its shaken/bumped and would like to solve that.

Oh, cheers, I could actually cut it out of foam rubber, without even firing up CAD or printing soft stuff! I might need new cells before doing that though >.>

Hi Hank,

Any chance the new SST12 is offered in your Quad boost driver lights?

2 Thanks

+1 to that. My Wurkkos FC13 with the 18350 tube was suffering from the maraca’s syndrome – shake it and off it goes. Hopefully fixed now after almost effing the light (pulled on the tailcap spring with pliers to try and get it to distend a couple of mm more, just to have it come off in my hand – and it was not either easy or fun getting it back stuck in again).

After all, what’s the problem with dented / “concave top” (LOL) batteries apart from the aesthetics?

I am planning to order a Noctigon M44 as soon as it’s released. I really want a high output, high CRI, lumen-sustaining light. I don’t care much about the dual channel functionality. Can’t decide between 519A 5700K de-domed or 519A 4500K or 5000K domed.

Random thought: it would be incredible if Hank made a high-end light that had active cooling like Acebeam X75 or Wuben X1.

6250

Does active cooling make a real difference at such a scale?

My only wish for Hank’s lights is that they wouldn’t use PWM at all. I just realized, captured by my phone’s slow motion camera, that Hanklights use PWM to control brightness. Very disappointing, as I absolutely hate the use of PWM to control brightness in flashlights, lightbulbs, phone displays, televisions, computer monitors, car headlights, street lights, and so on…

Using my D4V2, for example, I can read PWM on everything but the top 3 brightness ramps. It may exist on the top light, but the PWM frequency is too high for my phone’s camera to see. Such a bummer. (I use an app called Illuminance Pulsation Meter.)

If you can’t see the PWM with your eyes because the frequency is way too high (which it is in Hanklights) I fail to see the significance in complaining about it.

PS: this is coming from someone who absolutely despises visible PWM

It’s extremely high rate relative to every other light I’ve seen to the point that I cannot discern it. A review with actual testing figures measured 16kHz.

Same. Cheap LED Christmas light strings are irritating with their sharp 120Hz full-wave rectified AC. LED taillights that use PWM for running lights are similarly annoying with their stroboscopic trails.

Both is good. I love the 5700/5700DD mix so much I have three single-channel lights with it. The combination turns out about where the 4500 should’ve been; ~4500K with optic (the 4500K Domed drops to ~4200) and while not exactly rosy, there is a profound lack of green. Nice beam pattern too. I also have 4500/4500DD DW4.

Yeah I see modern expensive cars driving down the road and they have crappy flickery lights. If you wiggle your eyes they leave a flickery trail.

1 Thank
6256

You can’t see any flicker whatsoever as you are trying to imply.
Even the need of a tool to “see” PWM is saying the same thing, that you don’t actually see anyting.

On the other hand smartphones using OLED at low brightness, you see the image being chopped when moving the display fast or the eye left to right because they all use 240Hz PWM, even the Iphone 14 Pro use the same low frequency.

One cannot conflate all PWM as being the same, because it is not.

For the M44, you can forget that it’s a dual channel light, but a single channel light with dual channel functions, since with the new UI written by TK, it can work as a single channel light competely.

Driver can be chosen?
If I understand correctly the light work with a double LEDs but in a single channel?

6259

driver can not be chosen, but you can choose the single channel mode via UI, which the light will act like a total single channel light.

2 Thanks
6260

So it’s like a D18?

1 Thank
6261

M44 is a dual channel boost driver light, you can choose the single mode function via UI, so that is will act like a single channel light, you can also choose the dual channel function via UI.
D18 uses linear+FET driver, which is a total single channel light, it does not have dual channl funtion.
They are totally different lights.

6262

No, there is not currently a d18 dual.channel

The new version on the anduril ui moved ramp shape (smooth vs stepped) to 6C for now.

3C is now used to switch between different modes. There’s a new menu to select the modes you want: in the case of 16x the same led, you would choose the “both channels on” mode so it acts like single channel flashlight.

Other modes include tint ramping, auto tint, ch1 only, ch2 only, and any of the aux colors (nice!).

Actually people who exemplify Sofirn as taking button top cells, well…

  1. Because I have flat top 14500 cells I can’t turn on my Sofirn SP10 PRO, so now I have to buy button top cells, because they use a mechanical reverse polarity protection where you can Only use Button top cells and impossible to turn on the light with flat top cells.
    So are they great for not allowing me to use flat top cells? Since no one else has this problem is not a problem.

  2. Some like Fenix E09R can’t even replace the cell. Or Olight’s proprietary system of cells.

  3. The D2 unlike Sofirn SP10 Pro has components on the bottom of the PCB, so it can’t go with the same reverse polarity protection as on the model and force to only use Button top cells, they don’t have room.

Definitely a spring in the front and a spring in the back is a good solution to not have your flashlight turn off when you shake it or you are on a bike which is highly annoying, especially for beryllium copper less “springy” springs, but the issue here is the tube is too short, that would be what the dented cells indicate.
