Does MF01-S work with the 8×18650 tube? I don’t have tube, but does it put out 9v? I assume it puts the two sets of 4 in series.. the MF01 non-S input voltage has a range up to 9v so that’d make sense. MF01-S doesn’t have any input range given?

This light is 6v (8.4v).

An 8 cell battery tube would need to maintain 6v.

The existing Astrolux extender works in parallel not series with MF01S just like with original MF01. You will need to buy additional one end cap and have two loose battery cages since new MF01S changed design with integrated battery holder.

are you alone in the house?

Does an expanded tube help with heat dissipation?
Or, with 8 batteries, does the lamp adjust in high / turbo mode just as fast?

The vast majority of the heat is at the far end of the head, above the switch level. So the battery tube heat dissipation is very small. I doubt you will see much heat related difference with a longer battery tube. Any difference will be tiny and you might not notice.

Turbo stepdown should not change.

Depending on batteries, you might see brighter Turbo output which means it could heat up faster.

I think the main goal of using 8 cells is just longer runtime. All run times double, except where heat might cause it to ramp down.

I have two MF01S (4000K and 5000K) using the astrolux extender tube (about 20€) and they work nicely! The original MF01 worsk with it as well and the MF04 ditto.
No Problems whatsoever.
The main advantage is longer runtime. In real world I don’t see an output advantage (i.e. more light on turbo) but turbo can be maintained a little longer…

But be aware, this then is a heavy flashlight and no beauty since the tube is nearly as thick as the emitter end Wink

Cool just extender tube, extra caddy, and tailcap in.. hooked it all up and yeah works just great. Yeah its mostly about runtime.. I’m pretty sure output is a bit higher as well. I can’t really see a difference, so its not huge deal, but just based off heat its driving leds harder. I had setup ceiling to be at point where light just was slightly warm in hand, was like level 100/150 or something. Switching to extender tube same level is now noticabely warmer, so more amps must be flowing due to smaller voltage drop with twice batteries in parallel.

My Mf01s came without the physical reverse polarity protection rings.
Did they change the design? Does anybody else have a Mf01s without it?


In this vietnamese youtube review of the Mf01s it seems to be the same:

Mine came also without reverse polarity protection rings.
Was delivered early december. So it seems they changed it quite a while ago.

Thanks for checking.
I bought four Samsung 30Q button top because I thought it would come with the protection. Would have taken flat tops if I knew before.

Well, I’m happy they work both, so I can use my Sony button top or Samsung flat top.

Mine was an early MF01S and it has the protection rings.
Thats not good that the newer do not have it. That was the best polarity protection rings on the market, because they works also with all flat top batteries. E.g. from Samsung, which has the contact lower than the heatshrinktube around the flat top.

My MF01S was purchased after the first round of colors was long sold out. I bought purple when the colored became restocked in Beginning of December so mine is very newer. I use flattops VTC5A. Mine has two rings down inside battery tubes on positive posts, but none on the tailcap’s end. I watched Flashaholics video and his had two on the tailcaps positive posts. It seems Astrolux did this inconsistency and should send ones missed. Every time I read threads on this forum I find more issues with their stuff.

I dont see the problem, everybody buying this light should be able to insert 4 batteries correctly. Otherwise this light is too dangerous anyway.
Make sure for instance all 4 batteries are fully charged to the same level when you insert them, otherwise it could get really nasty…

People expect to get what they paid for. Surely you understand what it’s like to buy something and parts are missing. It’s irritating.
