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