Just acording to what the driver says - “HX-19023” - I found this russian site: Драйвер 32мм HX-19023 с мех. кнопкой 32mm 6A - 927 руб.

Thank you very much!

Kensun SST-20 → Wasserdichte starke Licht laterne Hochleistungs-LED-Taschenlampe mit fluor zieren dem Logo Typ C USB wiederauf ladbare ultra helle Taschenlampe - AliExpress 39
I really like the heatsink here, it just looks nice.
vs Convoy S3
The retaining ring was loose
Driver / charging circuit
SST-20 LED? With way too big gasket
The crown sticks above the case
The construction is a bit weird, it seems to be from a zoomy-light, because the pill isn’t screwed into the head, but into the body and then the head gets placed over it.
The heat has quite a way to travel to get to the heatsink
Pill itself
And this is where it dawned on me that in the back there is more than just a digital switch and charging circuit like I hoped, but also the whole driver. That makes a driver swap hard to impossible.
At least the original driver has no blinky modes in the normal switching.
Material: Yes, Heasink compund: No.
Beamshot:
Lens: 24.2x1.2
Reflector: 22 (W) x 20.8 (H) x 7mm (opening)
Place inside the head: D=23mm
I am thinking about a swap to a triple or quad-board with lens, but first I need to have a new driver in this thing.
I am currently evaluating if I could open up the switch-openings on my lathe and maybe with the help of a little 3D printing put in a normal switch…
For the money you get an OK light that looks different than others.
1 Thank
Neeeext!
No blinkies, modes are: low, med1, med2, high, double click goes to turbo which unfortunately is followed by strobo ans SOS. Long click from off or on goes to red light and red light strobo.
The LED Board sits on a pressed in disc. not super thick, but hey, it’s something!
even thermal paste was used.
I like it, it is short but thick and the 5 LED-optic looks nice, haven’t seen 5 LED-optics until now.
The cell, 18350, claims 1500 mAh, has 1057mAh after first charge.
1 Thank
Yeah…
Modes are: High, mid, low, double click is turbo, hold gets you to strobe
Cell, 18490, claims 1200mAh but has 1240mAh.
Since I ordered the next 2 flashlights just 2 days ago, there will be a longer waiting period…
Edit: Just remembered that a light each from Convoy and Firefly are on the way, phew!
Edit on 21.02.25:
Just discovered that the lenses that Convoy sells fit perfectly!
This is an awesome thread.

This time: 26650 Kensun Zoom-Lamp
Saw this light basically everytime I went on AliExpress, so when the price dropped to around $18 I bought one.
Put a battery in it and wanted to see with how much current the lamp charges - it was around 1.5A at 75%
Weirdly, the charger was still charging happily after the display showed me 100%… The battery was at 4.1V at this time.
This is NOT a 5050 or 3535 LED, this is a 7070 ON 20mm COPPER DTP Board! I couldn’t believe it!
Diameter of the LES is ~2.8mm
Printed something from Polycarbonat to unscrew the pill. Still had to use pliers, so no chance of disassembling this light with standard tools.
Thermal paste was in use.
Pill has around 5mm of aluminium under the LED.
I cannot show you the driver other than like that. The voltage display catches the rubber of the switch and it blocks it.
The driver has Hi, mid, lo and two blinky modes.
Quite a long way for the heat to travel until it’s at the heatsink…
I would say, one of the better lights for people that don’t want to bother about their flashlight and just want a bright zoom lamp.
The lens is made from plastic.
I will swap the LED for the “L75” from Kaidomain. THe LEM is a little bit smaller.
Maybe I order that 1mm² Osram on 20mm star…

Got an Convoy order with a bunch of lenses.
This one fits with a little bit of grinding, the height seems to be perfect.
Just the upper outer ring must be grinded smaller.
I had to repair a pcb track that blew because of a short that I somehow created, so while I was at the driver side, I changed the blue LEDs to white ones.
Looks bluer than it is, because the room light is 2700K.
Now the beam looks so much nicer than before and this light is actually very usable even with the original LED.
Sooo, I needed a new light for my keychain since the battery on mine was so weak that it didn’t turn on at all anymore.
I bought 3 lights this time.
This because Boruit is some sort of “brand” and I expected this to be the replacement that I will most likely use
This one because it looked nice and I wanted to see how good it was:
And this one because it has a zoom function.
Turns out, the Boruit was the worst of them all.
The beam pattern was super bad, inside was yellowish with a blueish ring around, just overall ugly.
I changed the LED with a 519A and took the lens from my old light and put it in. Now it is better.
The switch feels and sounds cheap. Is is kinda recessed and not easy to find.
UI is the same as they all have, one click gets you nothing, double click goes to Lo, Mid1, Mid2, Hi, Double click from on goes to Turbo, triple click activates the side lights in various order.
The second one was good without modification, but I still put in a 519A. Smallest light of them all, nice wide beam, even pattern.
UI is Low mid High, double click gets to turbo, Long click goes to white flash, one click more goes to red and blue flash
The zoomy one is my favorite. As long as the Boruit. The original LED was a generic 3535 round-die LED with horrible blue white low CRI tint. Now it has a SFT-25R 5000K.
The zoom function works great, but it has some artifacts in the beam because the ring that holds down the LED is silvery and reflects light.
UI is Hi mid Low, double click gets to turbo, long press white flash
The switches of the latter two are pronounced and easy to find but need some force to activate, which for me is a bonus since these are meant to be on your keychain and it is a good thing to not have a switch that activates easy there.

Yesterday, this light came:
Back then $16.79 with the cone
I like how it looks, nice green/bronze color, thick but short… And so is the light.
Well…
I tried it, didn’t work. Second mode - a friggin Laz0r, did work. So the driver and battery were fine.
opened it, solderpoint was loose:
After resoldering it, the light worked. Well, at least most of the LEDs did…
Then I tested the cell, claimed 2500mAh which is realistic for a 26350 - well, not even half of that, probably a 18350 repacked in a 26350 case?
I opened a refund and got ~$7 back.
Since I will cange te LEDs anyway, te defective (or probably just poorly soldered) one is no problem.

Love the numbers on the battery . I was looking at the pics to see what size the cell was and thought ok well you have a decent battery …. Until I read further . That’s pretty sad / and they took the extra effort to write such nice things on the side of it ….
Does the Laser work? I have a cheap seven 5mm AA light with a red laser that is fun for about 12 minutes every 6 months . If it didn’t have the 3400K hi cri 5mm leds it would be closer to 2 minutes .
- Note to self …Don’t buy lights you can’t pronounce. and of course >… kill bob mcbob
Next contestant:
Price paid: $17,88 incl. 1200mAh 18350 Cell
Cell arrived with 3.98V
What I don’t like is the color difference from head to tube. Quite noticable.
Some generic 3535
Having it on for some minutes shows a good heat dissipation throughout the lamp.
Turbo from 1m:
Lowest mode from 1m:
I am testing the cell and trying to fit a LMP LHP531 in there.
Edit:
Modification done.
Just perfect!
And if someone wants to see the OG LED up close…
The MCPCB is a copper DTP Board by the way! (That’s why it is scratched on the pictures)
Edit2:
Measured the modes @4V:
Low: 114mA / 0,45W
Mid1: 445mA / 1,78W
Mid2: 1,9A / 7,6W
High: 3,55A / 14,2W
Turbo: 6,1A / 24,4W - My PSU only can deliver 6,1A
Edit3:
It seems that the charging of this light just killed one of my Vapcell MII V2
Better glue the port shut…
Please read the next post for more information on this!
Edit4:
The cell has measured 1171mAh after first load

Ok, I have to make a new post because I must clarify something.
I don’t want to be unfair.
I did put in a different 18350 and the light heated up by itself.
Then I remembered, that I did use my Lab PSU that destroys drivers, as written in other posts in this threads.
So I used my other (Riden) Lab PSU and saw, that the driver draws 1 Watt while doing nothing.
Then I grabbed my IR cam with the Closeup Lens and located, that the 4056 charging chip was hitting 90° after a couple of seconds.
Again - the led was not on, just voltage to the driver while off and not charging anything.
So, I changed the chip and fixed the problem.
Draw in Idle was now not measurable.
Was.
Because when I checked the amperages again, the Chip drew 1A in Off and burned up again.
So then I decided to just remove the chip and the USB C Port and use the light as a light without USB charging.
I want to be very clear: I am 100% vertain that my faulty Lab PSU did this.

Looks more like a 3030 led on a 3535 MCPCB

@L4M4
I just want to appreciate all your posts here, the experiments and the lights you are showing and that probably wouldn’t shown if it was this thread!
I’m an avid AE searcher and find these lights often, but question myself about their quality. Turns out some of them are nice and have potential! Thanks for showing them !

Bezel can just be unscrewed with the friction of the fingertips, not waterproof!
Looks like a standard 20mm Lens
After unscrewing a aluminum ring the inside just pops out the front.
Not much meat for the heat, but a copper DTP-MCPCB, didn’t expect that.
Charging circuit and back-LED
Won’t take it apart further than this.
The LED on the back is so dim on the outside, some lightened up switches are much brighter. Don’t know what this is actually for, maybe they reused an IC from a light with a COB or something?
Maybe as a ultra-giga-low-powered night light?
Changed the LED for the LH351D that I pulled out the Sofirn HS22 earlier this day.
For the money it’s an OK system, ready to go, just won’t last too long. Not something for a night walk or so, more for people that use a flashlight every 3 months for 5 Minutes.

You described my impression when I came across this forum)) I also like to look for something interesting, and when it comes to live reviews… I’ve been reading the posts for about forty minutes, to be honest 
1 Thank
Last one for a while again:
“T13” from the world known famous brand “Aplos”
I paid 15.26$ for it with the cell.
Packing looks a bit like Sofirn, two instructions that you have to remove the little insulator
Fancy yellow protection on the lens - I like this more, on the Convoys it can be hard to see if there is any.
Quite a deep charging Port, small status light on the other side
Reflector and Gasket:
LED - the MCPCB reminds me of something, have seen that before. Sofirn? Wurkkos?
Cell will be tested (Edit: 2958mAh first test)
Switch, feels quite nice, it sticks out quite a bit, the light still tailstands, but not very stable.
Driver probably glued in? Not so nice…
Aside from the unreachable driver, this light seems to be a nice alternative to the classics in this size and brightness-class, just with USB charging.
3 Thanks
Reflector and MCPCB look just like the ones in my Sofirn SC31 Pro

You’re fulfilling a silent dream of mine, buying cheap AE lights and tearing them down. I really enjoy this. The diversity of the builds/quality are interesting.
