Got my second MF-01 today. It is v2. The tint is a little less pink, more yellowish compared to v1, though the difference is really small, I can’t see it on photos.

Don’t have an integrating sphere but my impromptu meter (luxmeter in Xperia Z3 Compact + ceiling bounce) showed (med1 / / med2 / / high/high after stepdown / / turbo) 43 / / 82 / / 201/120 / / 625 lux. On nearly drained battery it was 26 / / 64 / / 181 / / 420.

12cm fan with 9V placed close to light was enough to keep it on turbo without much reduction in brightness: The brightness during discharging: Imgur: The magic of the Internet (in a slightly different place, so the lux values are slightly lower). The batteries weren’t fully charged, I have realized it after starting test… I will repeat it after with 4,20V 30Qs

I don’t exactly know if the overdischarge protection works well - after inserting nearly depleted batteries (3,05V without load) breathing light started on green, only after turning on suddenly dropped to blinkling red. And still was able to get 2/3 of total turbo output, so the voltage on load should drop below 5,8V… unfortunately can’t measure exact voltage on load. But it should be ~0.5V drop at least…

The button is only a battery indicator when the light is on. In off it is only a locator breathing light that is always green. I find this to be an unfortunate feature.

but with turbo output and ~6000 lumens (2/3 of turbo output on full batteries) batteries that have 3,05V without load surely drop way below 2,9. And on 2,9 per cell it should turn off.

With a little cooling (a 120mm computer fan, driven with 9V, close to light) it can sustain close to 3000 lumens output with only a slight drop (rather due to voltage drop than thermal stepdown).
This is the output chart (same cheap method as before phone luxmeter + ceiling bounce) on high with fully charged 30Qs . Two last spikes are from mode cycling, first is a fluke. After last mode cycle the light started to blink red, so I turned the light off. The battery voltage was 3,1 unloaded, so I assume the light start to blink red below advertised 6,1V… unfortunately I don’t have lab PSU, and can’t check it exactly.

Not fitting.

Hmmm. On my V2 the light turns red at 3.7V resting voltage + turbo = 3.4V (=0.3V sag). which is good. There is red and red blinking. Red blinking should occur under 3.05V, so does this mean your light does not turn red at all (3.05 < V < 3.4)? LVP kicks in at 2.8V from what I’ve read, and according to HKJ’s comparator at 10A with 30Q, you can get turbo output (close call though) with 3.05V resting voltage, resulting in a tad over 2.8V (with turbo).

The lower opening is too small. these are conical holsters for long flashlights that come out from the bottom hole: https://www.aliexpress.com/item-img/MAXTOCH-Flashlght-Flexible-Size-Nylon-Holster-Flashlight-Bag-Suitable-for-Most-Large-Size-Flashlights-Free-shipping/32601427375.html?spm=a219c.10010108.1000017.2.37b29a39QEYBSh#

It is a nice explanation :+1: 219C is out of stock.Will the hits come next product? :smiley:
We purchased the XP-G3 that we had stock in the meantime.Thank you freeme.

Thank you for letting me know :slight_smile:

219c will be again available on Nov.29

I bought XP-G3 yesterday, are they already shipped the version without problems?

Well, I will purchase it on arrival.I’m wish is Astrolux to make a holster for MF01.

XP-G3 V1, Intelligent temperature control setting was high :frowning: The possibility that XP-G3 V2 is getting better is high.

219C V1, Intelligent temperature control setting was optimal.
219C V2 is set down, and turbo step down is done immediately.
219C V1, the coloration of LED is also wonderful, it is the best thing if it works normally :slight_smile:

Personally I liked the v1 tint a little more. Though there isn’t as much difference between v1 and v2 - camera can’t see it, eye can… a little. Color rrendering is nice on v2 as well, so it looks like is still 90 CRI.

v2 - Turbo is stepping down after ~80-90 seconds and pretty slowly. I like the 3000lm High mode - wit a little wind and not too high temperature it can run for ~90 minutes straight, without stepdown. With the computer fan I mentioned it was ~37-38 Celsius.
Also, while the body temperature was controlled nicely in v1, the driver temperature was another matter, my light was capable of runniong few minutes on turbo without stepdown, but after that it was shorted - I could not turn it off. So I suppose ‘better darker than sorry’ :slight_smile:

Thank,
Are they sending the v2 XP-G3 ??

Do PROTECTED cells fit in this battery carrier? I was told that the Mateminco MT35 and this light use the same carrier.

What are the LONGEST cells that will fit in the carrier?

I want to use either MJ1 or Panny/Sanyo GA’S BT. It will be modded and he states: Protected cells Only

GA Dimensions: Dimensions (including button): 69.7mm length (±0.2mm) x 18.55 mm diameter (+0.1 / –0.3 mm)

MJ1 Dimensions:Dimensions:[Including Button] 69.6mm length (±0.3mm) x 18.6 mm diameter (+0.1 / –0.3 mm)

Thanks

its won’t fit, if you not remove plastic disc

Would they fit if you remove the white plastic rings or are they just too long?

I suppose if you were going to use protected cells only you could swap to a shorter spring.

Mtn Elec sells a nice spring that compresses really well. I’ve used these when I needed to fit a long cell and the stock spring just did not compress enough.

This is a new spring that is quite short. It looks great for long, protected cells, but might not be long enough for short, unprotected cells. I have not tried this one.

You could buy 4 or 5 of each and try them out, assuming you can solder.

OK,Thanks XXX and Jason.

I have a nichia v2 and can confirm, that on high (2nd highest level-3000lm?) it will run for around 45 minutes until first recognizable step down.
Lamp was tail standing during test run in my bed at 23°C ambient temp.
Just touched it shortly now and then to feel the temperature…
It was almost cool, and heating up very very slowly but constantly until step down.

On highest level step down happened after 2 or 3 minutes… Did not measure that time…

Do you think this is it?
