My goodness. Reading this review really makes me fall in love with this light over and over… You have measured one gripe that I have with this light. I personally have noticed on my light that when it steps down, it does this all the way to about 1500~2000 lumens roughly according to my eyes. You have measured 1700 lumens from high and 2150 from turbo. The light should be able to put out more lumens. But then again, after a long period of using the light at this reduced output gives you sufficient temperature head room again for the next turbo output. This light is just awesome! 
Well , thermal stepdown is really good for occasions like this , to maintain your hand in excellent condition
Awesome budget super bright flashlight .-
Hmmm… 3,5 lumens on low? That means they have changed low mode, in mine it was ~80…
Also, I strongly suggest unscrewing the light when transported. Should something fail, having 4 high current batteries shorted won’t be pretty.
Nichia 219C has good color rendering, very worthy. Good flashlight with good price
Hmm that’s interesting . I’ll check my notes and measure it again tomorrow…
Is this light the first batch ?
my only wish is that they regulate the output after 2.5minute drop down 
So glad that I picked Nichia, it looks awesome! In the very beginning I was leaning toward the XP-G3 because it’s brighter. And that is what most of new flashlight people are looking for. However, after sticking around BLF and found that a lot of people would rather pick high CRI over high lumens according to my observation.
So this is what I do… I have one big lumen light (HaikeLite MT03 in CW) and have one high CRI light (Astrolux MF01 in Nichia) just to balanced things out…
Plus, the holiday season is coming… if I really like this MF01 then I certainly will be looking for another one in XP-G3 and see if there are any specials going on during those holidays (Christmas, New Years/ Chinese New Years etc.)
seems as though this may be a heavier flashlight (with cells installed) when compared to other comparable sized “pop-can” style lights that are currently on the market, yes ? just curious, thanks.
btw : would there happen to be any other sellers besides banggood (within the states) possibly carrying this model ?
“Here is the tripod mount . It’s probably 1/4”
I think 3/4”.
George, please fix the photos. They are too heavy and I cant download full page with 4G.
Yes !
BLF Q8 weighs 588gr with batteries , while MF01 weighs 730gr with batteries . For me , it doesn’t feel a lot different when i hold both .
Hmm , i have made a mistake . Flashlight has a 3/8” mount , and with the adapter it is 1/4” ? I think it is that way
Thanks for the review George. Appreciate the runtime graphs!
It woluld be nice a 2-2,5K lumen mode. It can hold constantly.
thanks very much George, appreciate all the great info, and all the hard work on your excellent review :)

FreeMagenta, do you have a MF-01 with 6 wires to the MCPCB or a revised MF-01 with 2 wires. I don’t understand why you are saying that they changed the low mode since the MF-01 reviewed here is the old one.
I wonder if bypassing the springs on the battery carrier would result in any performance increase. :sunglasses:
I bypassed carrier springs and it made very little difference. If a a light isn’t fet direct drive it doesn’t help much.
+1 the pictures on the large/heavy size. And my take just a little too many as well ;-)
