Got my MF01 today. It works perfectly. Was happily surprised that it uses high CRI (>90) 219Cs. I thought it used the standard CRI80 219C 5000K.
The tint is absolutely beautiful, no shift to speak of and no other anomalies. The UI is quite the step up from the disaster that was the S42. All in all a superb light for the GB price!
Some PWM (or other flickering) evident on a cellphone camera on all modes except low but not visible to the eye. Didn’t have time to scope that out yet.
Output is not quite what is claimed, but I don’t care. For comparison, it produces 45% more lumens (35% more at 30 sec) than the Noctigon Meteor M43 equipped with CRI80 219Cs. My lumen measurement seem to be about 5-15% less than other people’s, but mine is calibrated with a reference halogen bulb and I use a spectrophotometer instead of a lux meter.
Output with Samsung 25R (lowest IR of any of my cells):
Throw:
0 sec: 44575 cd
30 sec: 40648 cd
