✌ FREEME - ASTROLUX MF01S 15000lm Flashlight Group Buy - ENDED

Thank you so much! Cheers!

You got mail.

I may be a bit out of touch these days, but can someone tell if the overheating and quick lumen dial down has been resolved for MF01s mini? Also I saw someone was offering copper heat sink cover plate separately. Is this still a separate thing that has to be separately installed or do the stock models now come with this copper cover plate ?
Thanks !

Hi everyone, my first post here. I just read all 49 pages of this thread, quite the journey!

I ordered my first “non-typical” light! Should arrive in the next few days. (MF01S Sand 6500K ordered on BG)

I saw some posts and threads that advised pre-use actions ranging from cleaning to led-reflow and repaste, to ensure it does not burn LED’s due to low thermal conductivity from bad solder job.

I have’t taken apart any flashlights before, but have some limited experience with a soldering iron etc.

I was hoping some of the experienced users could give me advise as to what you think I should do before first use:
1: Disassemble main components and clean with alcohol?
2: Lift LED board, clean factory thermal grease, and apply high end CPU thermal grease? (Non electrical conducting Grizzly Kryonaut)
3: Attempt to reflow LED’s. (Very scared of this)

Also, I already bought 4 VTC6 flat top batteries, planning to remove the reverse polarity protection rings (If they are even still included with the light?) and just being VERY careful when inserting the cells.

The brightest light I own right now is an Olight H2R that I edc, so looking forward to some “real” power!
Thanks in advance,
Cheers

I would just use it normally.

Don't fix something that's not broken.

Instead, simply give it 5-10mins visual inspection to look out for:

  1. Loose or missing parts for springs and connectors.
  2. Perform continuity test for battery carrier/ compartment.
  3. Condition of flashlight threads. Clean off any residues to reduce wear and tear.
  4. LEDs for dirt, burn marks or chip off parts.
  5. Solder joints leading to mcpcb, and leftover solder blobs which might potentially cause short-circuit.

Thermal paste upgrade doable but only if you are very keen to push the limit of the light and some spare time for it. Probably it is about 20mins job?

I am quite sure less than 1% of the buyers would attempt to reflow of those LEDs.

Thanks @freeme,

Yeah, I hear you. I am not planning to run it particularly hard or anything. I just want to to A: Not kill itself the first time I go to Turbo and B: Last a long time.
(From all the posts I read, I realised I should not expect Olight quality/reliability, but then again, the output and price/performance is also a lot better with a light like this. (Not to mention the UI, looking forward to that a lot!) So just trying to give it the best chance at lasting I can)

Think I will probably do the clean and thermal paste. I am under the impression I would not need to de-solder any wires or anything to get the LED board lifted to do the repaste? (I hope that is the case!)
Will turn it on before doing anything, just not go to high/turbo.

Will try to take pics and document the process, maybe someone else here finds it interesting.

Cheers
Q

Not that I’ve seen. This light uses Anduril which means it will adjust itself up or down based on it’s temperature. Other lights this size using Anduril tend to average about three thousand to four thousand lumen continuous. Maybe an owner can give us a more accurate reading.

You’ll definitely need to unsolder 5 wires if you plan to lift the MCPCB to change the thermal paste.

Dammit, that makes me more hesitant. Will check what it looks like when I do the cleaning, and make a call then.

Thanks

I’ve been planning to import these to sell, what’s everyone’s thoughts on reliability?

Have there been many issues? The last thing I want is have to be constantly repairing them

Group buy coupon please, plus diffuser and holster, whatever is available.

Could I please get a coupon as well? And ones for the diffuser and holster? Thanks!

Coupon please if still available, thanks

I am pretty sure that the thread is dead.
I am still waiting for the code myself from freeme, so I went ahead and bought the MF01S with batteries during the 9.9 sale. Diffuser and holster were bought seperately.

Probably for the best… I just found this site a month ago and I’m already out of control. My wife asked me yesterday “why do we have 40 flashlights?”

I had originally dismissed the idea of owning an MF01S when it came out as I regarded it as too expensive , so I bought three other lights instead :smiley:

Big difference in brightness 5000K vs 4000K? Color rendering much worse in 5000K? Is it true you can see the green glow at 5000K?

Do you realize that you are asking someone who posted that 9 months ago?
There is a big difference in brightness. 4000K is rated as 11000 lumens, while 5000K and 6500K are rated as 14000 and 15000 lumens respectively.
I just bought the 5000K version, much better tint than the MF01 mini 6500K (SST20x7) I have, no more green shift at low, its more yellow, than green. On the other hand, both flashlights pale in comparison to my Nichia 219c (astrolux s43).

Thank you for the information. I had the opportunity to compare personally. In fact, the 5000K seems a little brighter, but the 4000K CRI makes up for it. I choose 4000K.

can i still request a Group buy Coupon here?
