It’s seems crazy to say a light with 18 power leds needs a lower low but it would have been nice here. The UI isn’t anything fancy but compared to the mess of their S42, where you couldn’t turn it off without going to level 2 and if you try it goes to turbo and if you try at that point to switch modes you get strobe. Yeah, way better than that but not a big fan of the hold and wait to turn off but have been getting used to it in their lights and the Manker ones. Maybe it’s just their thing.
With my Nichia I messured only the following:
| Low | Mid | Mid1 | High | Turbo | |
| Specs | 70 | 700 | 1100 | 6800 | 11526 |
| Measured | 50,4 | 614,2 | 1168,7 | 3471,9 | 7425,0 |
Only measured turbo, but the XP-G3 measured at 11,900 at 30 secs with my PVC lightbox method, and throw was actually a little higher than spec'd.
Just got my Nichia! One bank is a noticeably dimmer than the other two in Low and Med (not enough to be noticeable to the casual observer on Med), but seemed to be gone by Med1. To get a good look (without frying my retinas out) I used a Shade 12 welding mask to look directly at the light at all levels 
. I could then see that the one bank is still dimmer on Med1, but only slightly so. On High and Turbo, all banks appear to be emitting at equal levels.
Only one little nick at the base of the head. I installed then took out the tripod mount, as the hole for it seems to be the natural spot to rest the head on your index finger.
Dedicated Extension Tube and additional battery holder doubling capacity??
One of troubles of this model.
After contacting BG, it seems to send a battery holder.
It becomes two battery holders, it is used for spare use or for verification, it is a meaning hit.
As soon as both heads are turbo with 2 heads it will be red indicator.
The battery is Samsung 30Q.
Once turned on, it became a green indicator with one head.
In the outdoors, the XP-G3 also showed no unevenness and was not bad.
I also feel a little bright.
I took some beamshot last night. Both Q8 & MF01 is very impressive based on cost–performance ratio! I estimate MF01 is over 10000lm. MF01 UI really bug me… it works, but I much prefer Acebeam, Olight or Q8 ’s UI.
:exclamation: *Sorry guys, I decide to take off some of my beamshot photos. I was so exciting about new MF01 & BLF Q8, I forgot to check the batteries in the lights before taking the beamshot photo. I recheck all batteries & found out none of them is fully charge 4.20V; only MF01 & BLF Q8 used fully charge batteries.
I’ll post new beamshot soon* :exclamation:

Just using a ceiling bounce test I’m reading the MF01 34.8% higher than my M43 meteor. So if the meteor Nichia 219c is 6600 then that would make the MF01 around 8897 or so. I had used it a little earlier in the day so the cells were prob at 90%. But I’m happy with a 9000L OTF NW. Also, I’m just using a cheap Lux meter and they don’t measure NW as high as CW since I understand they are more sensitive to more blue vs reds.
Also, I meant to mention like other Astrolux lights with the green eye, you can turn off the green dragon breathing light and lock it out by holding down the button for 2 sec. Then, unlocking it by hold it again for 2 sec.
Mine just arrived (219c), cosmetically perfect except for a very tiny scratch ~0.5mm long. Have to be looking for it. Functioning perfectly but only 5 minutes playing with it in full sunlight so far. Think I’m going to love the beacon.
Just hold the button down for < 2 sec. to turn it off / on. This is the lockout.
It would be great if you could measure all brightness levels too. Than we can compare it.
Perhaps I will open a ticket on banggood and ask for a new driver of the XP-G3 Version.
It is not good if the XP-G3 reaches almost the output of the specs and the Nichia reaches only 65% of it.
Thank you.It was very helpful :+1:
So what is your overall impression of Q8 vs MF-01 ?
I just got my Q8 as well and love it….BUT you can never have too many lumens right?
[quote=Gj]
Just noticed earlier that the light stopped breathing because of contact problems 
Thanks for that. Such an easy solution :+1:
I went out an hour ago (21:00 or 9:00PM) … Money well spent!
The downside is, that a FET driven XP-L seems to be very dim now 
Really wanna see legit calibrated lumen readings of all modes to see how they compare vs specs.
I just received my Nichia-equipped light and can’t wait to see what a quad of VTC6 cells does to the neighborhood night sky. Only a few more hours until we see.
I bought some smoke grenade pouches for my soon-to-arrive Q8 lights and the main body of the light fits but the top-heavy bright end sticks out and it doesn’t reach the bottom. There’s a lot of velcro holding the flap on so I guess it could work, but I’ve got a couple other larger pouches ordered that will most likely work better.
I also added a screw-in thingy inside the tripod mount so I can attach a sturdy strap. It sticks out kinda far but it keeps it from rolling. Here’s the link to see what I mean:
Searched the box thoroughly, I’m missing the pocket clip! 
2 questions:
1) Is it still possible to get a code?
2) how is the lamp stepping down, when set to turbo?
What’s the maximum constant output
(How it temperature compared to a Acebeam X80 ?)
(please send me both codes!
219C and XPG3 )
- Unavailable for order now.
- MF-01 has temperature stepdown function.
- Will leave it to the other buyers to answer this.
I swapped out the 30Qs that I ordered for this light, with the HG2s in my HaikeLite MT07. Seemed to get quite a performance bump over the 30Qs. Also, it heats up a bit quicker, and the power level does not go to red as quickly in Turbo. I had previously tried out the 30Qs in the MT07, while I waited for the MF-01 to arrive, with no noticeable difference in output.
I think I would go through all the carrier buttons and check that they are all soldered securely so I know I’m getting full power through them.
