There’s a ceiling bounce app available for your phone, calibrate a torch you know others have got a similar output on and compare it. It helps to use a frosted diffuser of some sort as throwy lights get an advantage. Use a spacer under the shorter light too so they are the same distance from the ceiling. I set my Acebeam up as 14,900 lumens and my DX80 recorded 32,114 lumens after a second or so then started dropping off.
Lux meter on the Google Play Store worked well for me. It saves the maximum figure recorded so you can go back and look at it. I don’t know how accurate it is as it will depend on the hardware calibration of the light sensor on your phone, but it is great for comparison.
If those just came in, can you take pics of the chargers.
The first of several of my friends that ordered should get his very soon also. He is wondering if the charger issue has been corrected.
He already has a 19v laptop charger ready to go if needed
After nearly 3 mths of waiting with a pre order with gearbest then swapped to banggood, my DX80 finally arrived!
It is bright all right and so far that is just inside during the day.
I charged it up using the Imalant charger and although it did get warm it made it through the cycle.
We are on 240v here in Australia, so maybe it is the 110v power that is causing failures.
