The rear button is not the power switch for the main light. I believe it is meant for signal purpose , or act as a flashlight location beacon?
Bruno28, have you tried different batteries?
The LED looks centered to me, but maybe the white insulator is not. Do you manage to correct it?
Its not batteries issue.
If you read my post I explain that its got flickering issues after I manage to disassemble the light and put it back which miraculously made it work.
I was able to correct a bit of the centring of LED. You can remove the whole Reflector head and get straight to the LED and MPCB.
Yes its only a Beacon, not very useful. Would have been best if it was a tail click switch like the older model. To be honest I think the older model is a bit better as it has a click switch and a magnetic rotating mode switch. So much easier to use.
Ill try both lights tonight, but seems like they are about the same in throw (even though the old has 200lumens more) and spot size when I tried inside, making the older model much more compact as its a smaller head.
I will see how they differ in throw tonight.
Yes, I understand that you dismantle and put it back, and it start to work, but it has flickering issue for mode 4 and 5.
I meant to ask do you try different batteries to troubleshoot the flickering issue.
So I tried my brand new batteries that I got with the BLF GT. It was better. But mode 5 had hissing sounds. Mode 4 didn’t seem to have issues and it was smoother during mode change.
Since its not perfect does it mean that there could still be some issue that’s not battery related? Or is the hissing sound normal?
I am not sure. Looks like mode 4 and 5 are regulated and battery age or contact will play a factor.
Highest mode is not regulated so it will just draw as much current from batteries as possible.
Ya, the hissing sound is mentioned in review posted in BLF.
hi my friend group by.I have a question How long after pay to receive a tracking number?. i select shiped by registed air mail
I purchased two BK-FA30S and first one arrived today.
I had a closer inspection and the LED is well centre also no mark on reflector.
Im very happy with the light and it’s a definitely thrower killer vs Astrolux MF02 :smiling_imp:
I will forward your issue to manufacturer.
I received my MM18III today and i am totaly satisfied!!! Now I’m waiting for my Vostro 
But i have a problem. The Charger is not for the EU. Is there a posibility to get one for the EU (Germany)?
Thank you freeme and Niwalker for the possibility of this Groupbuy!!!
Thanks Freeme:)
I got a mail from niwalker, that there are no chargers available for the EU.
But I found an adapter and it works fine.
Again thanks to freeme and niwalker!!
Ok so I got my second BK-FA30s. Anddddd it doesn’t work too. This one has over 15 imperfections on the reflectors, its so bad that my other BK-Fa30s reflector looks quite good. 
whats going on Niwalker!
The Nova MM18III I got today at least seems to be working perfectly.
