I received my extension tube yesterday. The contact plate actually looks different than on the Astrolux fotos.
The new battery carrier is made of aluminium (the plates and the sticks) instead of brass, so it weighs only 59g while the older version weighs 137g. I’m not sure if the conductivity is influenced or stays the same.
The extension tube was wrapped with bubble wrap and newspaper but there was a dent on one end that needed to be cut away with pliers. Otherwise the carrier would not exit on that end.
Same lousy packing, no damage though, some scratches of course.
Not work first try, need to cut a thin cardboard, put inside tail cap then tighten. Bingo, green led on. :+1:
Brass battery carrier design has replaced with aluminium since MF04 model (early 2018). Not much difference in terms of performance.
I agreed, bubble wrap plus newspaper might not be sufficient. I left a feedback to Banggood few weeks ago. Hope manufacturer could come out with a solution with increasing the price.
So someone tell me, on the MF01, does this add run time, brightness, or both?
Looks like the original tube as two sets of batteries in parallel, so does this double the voltage?
Operating voltage is still the same as single carrier.

I am a newbie, so help me out here. The extension appears to load the battery carriers in series, won’t that double the voltage?
If not, what is the point of the tube? What does it do besides add 4 batteries?
Thanks
Really awesome, the twin saved my arse on car project I needed a big light.It gave all my Astrolux lights extra points amongst the larger lights I own.
