Pre production sample [Review] Astrolux MF-01 4x18650 flashlight supplied by Banggood

the LEDs are wired in 3 pairs of 2S3P

the box is also coated with plastic the tape gets off without any residue or damage

Kids in the building traumatised thinking aliens are going to abduct them.

But these was not coated

Sorry about this off topic but I am too pissed because all the boxes that come from BG come that tape stuck

12000lm is rated for the XP-G3…I wonder what the actual output is for the Nichia 219C.

I did a 20x timelapse for the thermal stepdown

Looks like a good product so far, i am torn between this and Haikelite MT03.

Nice light, it may even give the meteor a run for its money. Many details can be improved, such as having the MCPCB wire a bit further away from the edge to avoid shorting, and better application of thermal paste (Although for this size it should not matter much, the light will heat up quickly anyways).

Swi from Banggood told me this morning this is a pre production sample Banggood received from the company producing them

none of the regular lights will go in production till the improvements and changes are clear

they seem to have reacted after the S42 issues to put more efford to improve the lights handing out pre production samples for testing, rather than go too early in production and find out later which issues the lights have when the first reviews show issues

the switch ’s light is not…perfect for me, it’s kind of unbalance

Nice review!
thanks

I find thesetemps a major problem.
They did build in thermal step down but it seems to protect the hardware and not the user, this is literally burning hot, unscceptable imho for a production light, for a modded hotrod it is ok but for something one buys stock a no go.

I’m pleasantly surprised, it seems like they did the details quite right. And I’m curious about the output too, the 12.000 lumen is for XP-G3 of course, the high CRI Nichia version is not specified but will be more like 9000. I like the looks too. And the beam is nice.
Still the first thing I do with any Astrolux light is take it fully apart and check, check, check! :expressionless:

Only recommended for the experts... Else risk catastrophic result...

That’s great to hear. I’m glad they’re taking the extra steps to make sure everything is right from the start. I really like the looks of this light and will end up getting one as long as there’s no known issues.

We have identified several issues back in June. Several parts will undergo redesign, and i am awaiting for their test results.

That’s very cool to work with the manufacturer for redesign and the best for Chinese products to get feedback for improvements…
I’m amused the way Chinese people adapt their way of thinking

Anyway can’t wait for this flashlight
Groupbuy Groupbuy…

Thanks for the review Lexel. Looks like a nice light once the kinks are worked out.

Quick learners. Definitely a good sign for Astrolux/Banggood. :+1:

@Lexel
Please tell Banggood their lamps would gain a lot if they use atiny chips or tell how to flash each light.
Some Astrolux lights could be brilliant lights with the right software. They should enable the flashaholics to fix their errors easy.

2S battery config with buck driver feeding 2S emitters? 2S li-ion operative voltage window (8.x down to 5.4V in this case) overlaps with 2S emitters driving voltage, which means you lose regulation early at some point. Stupid decision imho.

Dealing with certain limitations can be understandable with cheap flashlights in the name of cost. This is not the case.

Good for ANSI lumen rating, and good for ANSI runtime rating. So yeah, I want to know what output you get at 4.2V, 3.8V and let’s say 3.5V.

P.S. It’s not just 2S emitters, but those 2S are in 9P, so you have a lot more voltage sag.
