MF01S Astrolux Problem

LED Flashlights – General Info 18650 Flashlights

Hey guys,

My MF01S has just stopped working. It was working last night no problem but today I tried to use it for a photo and it wont turn on.

I have fully charged batteries 30Q Samsungs they recommend. I actually charged the batteries last night after use at 3.8v according to my charger and didn’t use the light till this morning.

I always mechanical lockout with a twist of the head, when not in use.

The AUX lights work fine and the LEDS give off a quick flash when twisting the power back on.

The switch has a working light but doesn’t turn the light on. No combination of button presses make the light function in any way.

Quite sad as some highly respected names helped getting this flashlight in the works… and was my reason for buying this particular light expecting quality internals.

If yr within 30 days its time to open a banggood dispute

If not it may be a DIY project

Reliability, warranty, CS are generally not a concern of flashaholics …

Maybe try factory reset: loosen tailcap,hold button,tighten tailcap,release until led blinks about 3s

Nope, nothing… I am within the 30 days so fingers crossed.

They will ask for various vids of the issues and there will be a lot of back and forth

Just keep nice and cool and point out the light is not usable as shown in yr vid

They will try to offer banggood points or a partial refund

Just keep nice and cool and keep pointing out the main light isnt working

At some point you might get an email asking not to file a paypal dispute because of blah blah blah

Just reply and say you hope to resolve this nicely without going to paypal BUT if you can resolve this then its a paypal dispute

Eventually theyll give u a full refund, or a new part, if not go to paypal

Consider yourself LUCKY this happened within 30 days … 6 months down the road it would be a DIY fixer upper project :stuck_out_tongue:

Great news! Banggood has decided to send me out a replacement head for the flashlight. This truly is a great flashlight so I’m excited to be able to use it again!

It turns out initially my troubles getting in contact with Banggood was because their emails were going into my Spam folder and I didn’t realize they were trying to contact me.

I’d like to assure you that Banggood does have a great support team and had no hassles sending out a replacement once they had verification to their solutions. They also thanked me for bringing this matter to their attention.

So if you are considering the MF01S be sure you will have a quality light, after all it’s basically designed by legends of the BLF community.

and thanks for your advice guys

Hi guys, I have this mf01s flashlight, today I just didn’t want to turn it on, I teardown it because it smells burned, on the pcb there are 4 burned components, two resistors marked R5 and two capacitors marked C1 as well as the regulator marked LDO. please can tell me the values ​​of these components?

Thanks

I answer myself. It appears to be a pi RC filter with 4.7 ohm resistors and 10 uF capacitors. I already replaced them and it worked again. Apparently C1 was short.
