Excellently. There will be an opportunity to purchase a second perfect copy Thumbs Up

MF-01 in turbo mode, it seems that the camera sensor doesn’t like it.

I feel that the driver could be the issue with my MF-01. The inital problem was uneveness in one bank, before becoming a continuous Turbo issue with the same bank. In very brief testing, I have been able to get it to operate as it initially did. However, after only one cycle through the modes, the bank returns to it’s current constant Turbo state.

So, my light’s issue does no appear to be grounding/shorting, as JasonWW speculated. Just a more extreme case of the driver issue.

I have yet to receive any further communication from BG. So, I continue to wait…and wait, and wait, and wait.

Forgive me, all. I’m really not trying to be a buzzkill on here. It’s just that it’s a little more than frustrating that after a week, my MF-01 still sits idle, and I still have no resolution for my light.

What did Banggood say? Did they want you to send the light back for repair? Did they offer you a partial refund and you keep the light? Have they ignored you?

You have an interesting device. Thank you for posting Thumbs Up
Compared to sunlight, 219C seems to be higher in color temperature.
People’s eyes get used to it, so it looks different from the one you see at night at different impressions.

The last valid response from BG, is that that they had contacted the MFG and were waiting for a reply. Freeme stated that the head of the MF-01 project would contact me soon, but that was two days ago.

I have the same problem. Probably not just a handful of us …

2 days? I’d wait at least 2 weeks and if they got back to me before then, I’d consider it a win. Smile

It’s possible they might want you to send the light back to them and they send you a new one. So maybe you’ll have a working light in 6 to 8 weeks maybe? I would not be holding my breath.

It was sitting in one of the many cardboard boxes I never opened for about 3 years, since my last move in a new apartment.
I really don’t know if it is still accurate but I used it a lot, long time ago with a toyo-view D45M and an old rolleiflex, both almost beated to death…but all is a matter of good lenses. Japaneses and germans were the best at making great tools, lenses, cameras.

I tried to measure the temperature of the MF-01’s beam but there is too much variations over the beam to have something relevant.

Here’s mine in lowest mode.

There are some slight differences (that I really don’t care) in tint and brightness but nothing that follow the pattern of the 3 banks of 8 LEDs. Probably only the small difference/tolerance within a batch of LEDs. Or two different batches mixed before soldering them.

Left / right 219C middle XP-G3(CW) WB5000K
In Japan it is said that the color temperature during the day is 5000K to 5500K in the daytime.
It may be correct that the camera is set to 5000K and 219C appears in white.


But actually you are looking for a color like this one….

ASTROLUX MF-01 Nichia 219C (Lumen readings..)

I have used some «known» lights, doing ceiling-bounce (over 1 meter), to build up a
possible reference table (in lumens for MF-01) using a conversion factor of 26.47. (This factor is not a calibrated value.)
I have used different battery types for this testing.
Hope I am close with my numbers.!!??

Advertised values: (Using Samsung 30Q)
100lm
600lm
1500lm
5100lm
12000lm

The light I received has been flawless, so far, and I like it a lot.
(I also have the XP-G3 incoming.)

I hope some other can back up my numbers.

^^^ Thanks a lot hunter1! Any chance anyone can do some measurements with cells at, say 3.9V and 3.4V or so? Just for an indication how well turbo output is maintained. Thanks!

seems to be inline with my own measurement or close to it which is 9600 Lumens on 30Q. There is no way this is a 7000 Lumens light at least not in mine.

According Tom E here 10.5A should produce 5660Lumens.

so i adjust my calculation.
MT03: 8738 Lumens

I think Toms L6 was CW, is yours also CW? I know the NW xhp70 has quite a bit lower output at the same amps.

On another note, I’m interested in another 219c, please.
