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

The light is a pre production sample, so there might be improvements for the final light

Update:
I did today a measurement of the beam intensity of this light

measured @5m 2080 Lux cold start

so I get 52000 Lux @1m for the Nichia pre production light

this is just the Luxmeter set to show save max.
starting the light, 3 clicks to highest mode
then move the light a bit to get its peak output

The light seems to have a slow temperature protection, when it is cold it takes about 2 minutes to reach the level

the temperature sensor seems to be on the driver, which is not good on the MCPCB would be more precise and quicker regulation

as I got no manual I cant check if its specified there

I will do a timelapse to show how the light does thermal regulation

nice teardown !

but i am very interested in the UI and output...

Lexel, did you get a chance to use it outside? Thoughts?
(Edit; this post was originally made before any outdoor shots were posted, lol)

No reverse polarity protection, no space for protected cells… This might be a deal breaker… Thanks for the review Lexel! :+1:

Pretty cool light. So are the LEDs wired 2s9p?

Too bad cool white XPG2 is not an option. I would dedome them and put in a FET driver and that would be a nice beam.

What a stupid craze to attach that tape right in the box!

Please do not use tape directly on the box

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.
