After chatting with my friend in Mateminco (who also makes all the Astrolux MF series lights) he confirmed that the 911 unbranded version is made by them for a customer who wants to sell in Amazon but decided to take a loss on the first few units he sold at $49 just to bump up pucblicity of his store.
In short, that light in Amazon is a real Mateminco product.
I prefer the modes on the 911 over my Version 1 MF01. And the slight difference in lumens on turbo is very hard to notice with the naked eye when you are already in the 10k+ lumens range.
Received the Amazon light today, exact same as Astrolux, price is now $109.95.
That’s going to be a slow sale at $109.00 when the group buy is still going on.

How are your MF01 keeping?I heard some quality issues, some driver problems?
Coupon please
it wont ship until april 3 ?
Processing time:Expected on April 3, 2018
April 3, but some time it can be a few days earlier.
Well that was quite early
If you could test the runtime on high and measure lumens/temperature that’ll be amazing. Just ordered a nichia one a few days ago. I’m really curious to know if V2 steps down on high as there doesn’t seem to be any runtime graphs of it.
Runtime on high of 219C V2, so that is about 3000 lumens right? Complete runtime test will be done indoors at room temperature, so there is good chance it will step down. Is this what you want to have tested? With Samsung 30Q?

Yes, with head temperature measured after 10-30 minutes if possible.

Sure. I’ll probably have time tomorrow, so you should see results within two days.
I can also do with cooling if you want. I assume you don’t want the total run time until batteries are depleted; battery of my lux meter was about to die as well so I had to stop anyway.
I've never noticed a graph like that before...
It looks like 100% Relative Lux = 50°C
and 50% Relative Lux = 25°C
See the problem there?
The Y-Axis represents two different things.
It’s a little bit more puzzling indeed. The black line is relative lux, so use left Y-axis. Red line is temperature, so use right Y-axis. The common variable is time.
Nice work! I did actually want it till the cells are almost empty. How long do you think it would’ve run. Maybe another 70 minutes? And was the head actually that cool. If that temperature reading is right this has a lot more potential.
Well steady state is about 1500 lumens, and after 70 minutes cells were at 3.82V, so only a drop of 0.35V. So it would take definitely a lot more time than 70 minutes for fully depleted cells.
But the real run time would only be useful if you leave the light unattended. And if you intend to do so, then I see no reason to use level 4 of ~3000 lumens, as it’s going to step down anyway after 10 minutes.
If you really want the actual run time until battery depletion I can redo the test tomorrow.
I would love see the full test. my guess is 3:30 mins. Also is the lower mode 1650 or less?
