Hello my dear friends!
this "review" is not really finished, but i hope you can get a first impression and maybe ask me things i can add later
lets start with looking:
the flashlight arrived in a nice cardboardbox
really nice size
compared to the well known “C8 Style” and the smalest 26650 flashlight i own, a DQG Tiny 3th
and beside its cell (not included)
a look into the frone unveils a Cree XHP70.2 LED, a OP reflector and a ARcoated lens holded by a flat bezel
a lot cooling fins and the rubber sideswitch (RED LED for undervoltage warning underneath)
on the tail end the lubed threads are square cut
and show a variant to the usual spring in the tailcap
Same construction in the head
therefore the light is picky with the cells…
66mm is too short (needed a 1mm neodym to contact)
70mm is too long (was dented a bit on the positive contact)
tube on the front end has regular threads

some white wall shots & power meassurements:
f/2.2 | 1/50sec | ISO 200 with Huawei P9
Amps measured with clamp meter and bench power supply @4,1V
OFF 0.002A parasitic drain (jumps to 0.001A)
ECO – 0.019 A
LOW – 0.2 A
MEDIUM – 0.745 A
HIGH – 2.45 A
TURBO – 7.45A
low voltage warning :
came on 3.0 V (red flashing LED underneath the switch)
light shuts OFF on 2.5 V (red LED continues flashing – but power consumtion is only 0.003 A)
conclusion so far:
+ i like the ODF30 for the size and simplicity – which reflects in a good, achievable price!
+ 3500 Lumens seem reasonable
+ nice alround beam
+ working LOW power safety
~ the red flashing LED can in theory suck the cell into death in some months
– picky on cell lenghts
– no USB charging (maybe in a later model)
