Your measured lumens output is significantly higher than ZeroAir's, but graph line is about the same, interesting. I agree, Wurkkos needs to improve their drivers.
I have 3 different calibration lights, throw low cri, flood low cri and flood high cri, which we tested in real integrating sphere in local university. My measurements have about 5% fluctuation. Runtime graph shows approximate lumens with higher error, correct measurements are at the beginning of night shots. P.S. there may be difference in different flashlight samples.
You stole my fade transition with the drone, how dare you!!! Unsubscribed! lol just kidding. You'll eventually get tired of having to include the drone and reserve it for certain models. I only use it for high output models now, too much work otherwise.
