I bought a bunch of cheap flashlights from AliExpress - Thoughts

I paid $24.10/20,69€ here: Neue Edelstahl-Taschenlampe, hohe Helligkeit, 3000 Lumen, Metall, für den Außenbereich, große Reichweite, superhell, lange Akkulaufzeit - AliExpress 39

The reflector is aluminium, yes.
There is not enough room to put one extra driver into there to still have charging but a different driver and I couldn’t find anything for the used chip.
I was able to do that to other lights, but this one will be impossible.

The cell… it’s still testing, but my charger decided to charge it with 250mA because the internal resistance is so high (255mOhms in the beginning, after several new starts of charging/discharging it’s now at 139mOhms). That tells us that it’s far from being a high drain battery.

I’m looking for a cheap 16340 flashlight to use as host for mods. Preferably which can fit a 17mm driver. The Yemao looks good but it sounds too heavy. Anybody have any recommendations?

$13, battery included, easy to remove the mcpcb, not certain about the driver.

https://www.sofirnlight.com/products/sofirn-hs10-mini-headlamp-1100lm They’re great little lights, especially after an emitter swap!

Just opened up the battery cap, and on the end I measure an I.D. of exactly 17.00mm on my unit - the driver does not have any retaining ring, so I assume is glued in place, and can be popped out once the mcpcb is removed

Sorry right angle not suitable sorry.

I don’t really like 16340 lights, they are too small for my hands.
The only 16340 light in this thread is this one: 6500K Mini Taschenlampe Hohe Helle P50 LED Palm Taschenlampe Typ-C USB Taschenlampe Licht kind dame Rucksack Tasche outdoor Home Arbeit lampe - AliExpress 39
And with this lens it’s decent: I bought a bunch of cheap flashlights from AliExpress - Thoughts - #48 by L4M4

But this thing is not really a “good” host. If you switch to 18350 you have plenty of OK lights in this thread.

Yemao G40ProMAX

price paid: $24.50

Battery still on test, but the internal resistance is too high for it being a usable cell (~120mOhm) (Edit: Measured 4791mAh)
Also the top is dented quite badly (even though the light has two springs), it has been used before I got it so I don’t expect much capacity.

Other than the cell: Quite a nice light!


28mm Copper DTP Board with 3V 9-Chip 7070 LED



DUV: 0.0048 - It’s a nice cold white, no changes needes except you want a different CCT of course.


I quite like the switch style, feels and looks so nice!

I love that they used white LEDs for the battery indicator. Had a light or two with blue LEDs that were annoyingly bright.

UI:
1 Click: Low - Mid1 - Mid2 - High with memory
2 Clicks: Turbo
3 Clicks: Flashing

All I will do to this light is to change the LED to an LMP LHP73B 5000K - not because it is needed but because I have so much of them here.
Edit: LHP73B fits nicely, beam has no donut or other artifacts

Thanks for all that input. I find it very useful. Very thankful for your investing both, time and money.

Recently hits our local online shop, looking forward for the outcome after the led swap.
It does have a bigger brother; yemao 98K pro max, larger reflector (close to FT03 pro) and a 18650 and 21700 tactical with similar UI as Acebeam’s L16’s with independent electrical front and tailswitch; yemao A6 and A7
:flashlight:

I already had this one in my shopping cart, but since it is essencially the same light, just with a bigger reflector, I didn’t buy it.
Didn’t know about the A6 and A7 - but I have seen similar lights for less money, but since I am a big disliker of dual switches, I won’t spend my money on those lights.

Did anyone buy this light?

I like the concept a lot! Magnetic tail, adjustable angle, dual CCT (I think), constant current drive, IP67, but a little expensive for a cheap brand. Maybe it’s cheaper elsewhere…

What are your thoughts about this light?
