Cheap 26650 flashlight defective

Bought on Alie this flashlight:

and stop working.Start only in SOS mode sometime and stops only removing battery.

Any suggestion for repair/replace the driver, the led is OK.
Thanks!


No one can help?

Don’t bother with that driver… Swap with the one you like. Since this is around 20mm driver you could use it as a host and piggy back 17mm fet driver for example.

He needs an e-switch driver for this light.
This could be good:

(edit) Hmm… that driver costs more than the light itself… :partying_face:
That’s really cheap though. :open_mouth:

Thanks!
On led is written : XPG - U2
Will work fine with that driver?
Or is better to buy also a good led and yes will cost quite enough but I will turn the cheapo into a real beast?

This LED isn’t a XP-G2, it’s not even a Cree LED.
It looks like a LG or generic 3535 LED.


That driver is made for 10W LEDs - the LED here is 3W at max.
3Amps and this thing will be dead in a very short time.


https://www.gearbest.com/led-flashlights/pp_536609.html?wid=21 + the code “harvest090” = 12.99$
Or this Convoy for under 10$: https://www.gearbest.com/led-flashlights/pp_44144.html?lkid=10940187

Both are waaaaayyyyy better that this generic AliExpress-Flashlight :wink:
I would get the Zanflare.
Newer LED, in built charger and nice tint.

I have Convoy S2 and C8 on the road in 2-3 days will arrive,Zanflare cost too much for a budget member, I don’t want to move on candle forum :slight_smile: but I don’t know why I fell the need to repair that cheapo, I hear my brothers in lights screaming : mod ,mod,mod,mod !!!

I have two identical flashlights; but be careful about the changes: the LED does not have a dissipation base, it is only held by a ring, and the LED rests on the edges of the ring; Pil, in practice, does not exist

Not to sound like a downer, but honestly, I wouldn’t even bother trying to fix it. Into the trash it goes…

But it is a Superlight! :slight_smile:

Just direct drive it and be happy with high mode only. It won’t cost you nothing but don’t use it more than a minute or two continuously or you’ll cook the emitter.

That’s what scares me… :o

LOL :smiley:

I would like to see a tear down of it.
Maybe it’s moddable.

This:

Best deal ever for the F1.

Did you see the price?
It’s a steal.

I have a weak spot for cheapo lights too.
And for that price this seems interesting, with its 26650 size and an e-switch.
But that’s where the problems begin: The driver obviously sucks… And now yours is broken.
The LED is a fake Cree of course, so that has to go too.
But is it worth the work as a host?
How is the anodizing? (but then again, you could always de-anodize it in a lye solution)
How are the threads?
Does it have a tail switch too? (pics on AE suggest there is a tail switch)

Could you take some pictures of the parts and post them here?

Finally somebody understand: is a SuperLight and I cannot put to trash a superlight.
Don’t have cooper pill or authentic cree but found thermal paste behinde led.

Now seriously works with 26650 and I have couple and have very nice beam and strong enough for a cheapo.
What I have in my mind ?
Because allready ordered S2 ,C8 and now F1 (12.99-thanks) I want to use spare parts that I have , to adapt driver , drill tail and put there ordinary switch and back to life that SuperLight.

Ah, thanks for the tear down picture. :+1:
I can’t really see it too well, but when you say the LED board has thermal grease on the back, it means the pill has a shelf, it is not hollow.
A plastic reflector, but those can be good too.
Enough threads on the battery tube too.
All the O-rings are there.
How about the lens? Is it glass or plastic?

With a normal driver you could use the side switch for “turbo blast” :smiley:
You could switch a FET with that, or an extra bunch of 7135. (for example, 6x 7135 driver and 6 extra 7135 for ‘turbo’)
Could be good with a SST-40 LED.

ifratos flashlight works only in SOS. SOS mode will enter only by holding down the side switch for a long time; so for me, the driver is good but the side switch is locked to “on”

Good idea , I will try to change the e-switch before any modding.There is some way to by-pass to be sure that is defective?

Yes; insert the battery and then make short contact with the negative pole; it should enter other modes (low, strobe) for about two seconds, after about two seconds, the switch in ON will have the upper hand.

I removed the switch and here is the result

Obvious the driver is damaged so I start to mod….

First test ,working and comparising with ultrafire C8 on high:
