Yep.

Tail switches have one massive advantage compared to e-switches:
No standby drain.

There are some other advantages too, but less apparent and more complex to implement.

Maybe the e-switch part, mechanical switches are of course a thing.

But look what happened to the immensely popular H03 which costed only 25-30$. It seems as if they don’t produce it any more in favour of the magnetic charging version which cost a whopping 45$, that’s a 15$ extra for inbuild charging while a decent budget charger cost maybe 3$ and a DIY lipo charging module 50 cents.

S2+ 21700 quad: I’m in for it, should be a great fet host

I’m thinking the S2+ 21700 would be good with regulated buck driver. We already have the Emisars, Fireflies, FW3A for the high output FET lights. This can be a very efficient practical use light.

+1 on a 21700 with a solid regulated buck driver.

High output FET is fun for to play with for a while, but high sustainable output is what I’m looking for. Something like 500 to 1,000 lumens without throttling back due to heat would be outstanding.

These blunt statements seem more like opinions to me than they appear.

The part bout e-switches I probably said, or least was think'n, two years ago.

Our ATtiny designs still draw too much in parasitic drain, but if we turn off all the bling, the draw is so low, probably bout the same as leaving a cell in a power switch flashlight.

Here is the link to his AliExpress store. It shows a pic of it on the homepage but, it states “Coming Soon”. I think the Chinese New Year is winding down any day now so maybe it will show up for purchase soon.

BTW, I highly doubt he would email you from here, I could be totally wrong but, if you send him a message through his AliExpress store I am sure he will get back to you after the CNY.

https://convoy.aliexpress.com/store/330416?spm=2114.12010612.0.0.7ed3568...

BTW 2.0, I would remove your email address from your post. Might lead to a bit more spam than you bargained for.

I love the design and obvious Convoy quality of this S11, just wish it was an e-switch. This light is a no-go for me without one.


I’d also love the see the quality, low cost, and clean design of the S2+ or S3 lights as e-switches. Guess part of the problem is to many makers, the e-switch upgrade also implies USB charging, which it doesn’t have to. There’s also a lot of aspects to implementing a good e-switch:



  • consistent action and feel

  • placement

  • not too stiff but protected and stiff enough to not accidentally turn on

  • must be easy to locate by feel


The S9 is close but I don’t like the style,no ano color options, and think the switch could use improvements. I do though need to re-visit the S9. I bought one way back when they came out, but it’s sat on the shelf since. The switch design – feel and action were probably the biggest issues I had with it.


 

i’m ready to design another S11 version with side e-switch and micro usb port ,too

On the other hand, I love the reverse clicky mechanical switch of the S2+ and hope to see it back on one of the 21700 flashlights. And the bright colors of anodization too Smile

I’m very anxious to see the SST-40 and ramping driver, but SST40 is only cool white. I wish for warm tints. Hopefully it has a few useful mid-range currents (500, 800 mA) and not only fancy turbo.
Probably the ramping driver is suited for XML too, but more efficient than a 7135 Biscotti driver (Simon?). Then I can select the tints I like Smile

it’s ramping driver,so you can set whatever brightness you like.

26650… someone didn’t do his homework.

S2+ 21700 quad: I’m in for it, should be a great fet host, however knurling of any kind would be welcome, it’s a flashlight, not a dildo. Plus diamond knurling sells simply because it has a sexy premium look and feel.

E-switches are the future. USB charging is a gimmick that unnecessary rises the production cost. But as Tom E stated it’s difficult to make a good e-switch. Emisar and Zebralight are examples of (very) good e-switches. Fireflies however is an example how it went horribly wrong. The switch on their lights is so small and so mushy it’s almost impossible to use the light wearing winter gloves.

It’s a shame no producer yet has made a e-switch, ramping, single emitter non-hotrod light, with boost/buck driver as premium option.

ready to produce S2+ 21700,
no big difference from S2+ 18650,
diameter 24-24.5mm , almost the same as S2+ 18650
,but a little longer .
the reflector and pill are the same

So the quad Carclo optics will not fit in the 21700 S2+?

C8+ powered by a 35-40A 21700 modded with a FET and led4power spacer + 6x MCPCB gives some possibilities Evil

Simon, have you contacted Toykeeper about a ramping UI for that S11? I’m sure she can help you Wink

Simon, I’m very happy with your plans for the S2+ 21700 Smile
For me it is the extra stamina from the bigger battery that counts. For more power, the C8 21700 is a good candidate, and the S11 is a very good looking new flashlight too!

Hope they’ll arrive soon before the daylight time is getting too long Wink It feels like springtime in the Netherlands now (can still change any time though).

Simon are you planning to make quad emitter versions of the S2+ 21700 or will it be compatible with quad carclo optics?

yes ,i’m ready to buy some lens and make appropriate changes for the head,


A convoy S2+ for 21700 and quad emitters would be nice but I would suggest the convoy S3 base body for this new 21700 because of its front stainless steel bezel, easier for swaping TIR lens. It also has a head shelf for the LED’s MCPCB (a bit less easier for swapping MCPCB than with a S2+ pill).
The S2+ is probably more versatile concerning the height of the MCPCB + TIR lens which is nice for modders.

As long as the head front opening doesn’t cover the LEDs front reflectors of the TIR, a triple/quad S2+ or S3 for 21700 is fine.

I was expecting C8+ would have this feature.

I don’t care about E-Switch as I like rear clicky but I like USB port, preferably USB-C. Please make this compatible with carclo triple or quad optics too. Another idea is to have the USB driver and led driver separate like on the Nightwatch NA40
This way we can swap our own driver if we don’t like the stock driver. I don’t like the usb recharge in the Nightwatch NA40 hidden in the threads though. I rather it be exposed.

And like someone said, you can contact Toykeeper to help you design the UI. She designed the ones on the very popular Fireflies and I believe it is all for free. Also I like how Toykeeper’s Anduril has active temperature control. Only drawback is that when I gift Anduril lights to non flashlight people they often activate the many complex features and options by accidental clicking which can be annoying unless you are a flashaholic.

C8+ with 21700 with LED4Power’s 6x MCPCB would be freaking awesome.

I also won’t mind usb recharge since I gift alot of lights to family members and friends.

Poor Simon… Everyone wants knurling, and no knurling. USB charging and no USB charging. Metal button and rubber button. X and not X. Y and not Y. Z and not Z. Shocked

I think I’d just grab a coupla beers and slide down the emergency chute…

I can see the desire for USB charging, especially with 21700 lights and how it might be a tight fit on some chargers.

I’d just ask that it’s hidden in the threads so there’s no rubber flap to let in dirt, grit or water. A couple of my USB charging lights have pretty useless rubber plugs.

I’d agree with SKV89 about making it compatible with readily available triple or quad optics. The larger size (over an 18650 tube-style) could potentially make for a great modding platform.

Once again, I’m glad to hear news of new stuff around the corner.

That’s only 64 different configs so offer them all, i don’t see what the problem is. The easy way out is to just offer the best light ever. I’d buy that, the best light ever (as long as it can take a 21700).
Oh wait, you missed battery options, that’s 192 different configs… still doable imio.

(On a slightly more serious note i’m tempted by the S11 and am looking forward to the 21700 S2+, definitely going to get a couple of them.)

USB charging and no USB charging: See JKK26 Cree XP-L flashlight: a simple additional section can be screwed in between the reflector and the battery tube that contains charging and powerbank electronics. Simon can sell it as an add-on later.

My ramping driver is in production now ,It is controlled by a mechanical switch. I will describe the UI in detail later.
If Toykeeper has suitable solution, I will also produce the corresponding driver for BLFers
