Hallo,
Die Mail ist raus, hoffentlich blamiere ich mich nicht mit meinem Schulenglisch....

Hi Lillian,
Thank you for fast reponse.
My ZebraLight-H30 is from the second batch with the fixed UI-issue.
To give you and ZebraLight engineers a better idea what the flickering looks like,
i took screen shoots from a scope, showing the output on high, caught by a solar panel as measuring probe.
First pic is showing the output on high; please notice the spikes every 40mSec. causing the flickering.
Second pic is showing the spikes filtered with lowpass at 1kHz, to show the spikes waveform.
Third pic is showing the the operating frequency of the driver and it's harmonics. (no issue here, for information only)
Please forward this mail and the pics to ZebraLight engineers and make sure they are aware of what the issue is.
I know, that research and development will take some time, so i'm asking you to first make sure, that a replacement
will come without the flickering issue.
Once again, thank you for very fast response and taking care of customers issues.
Best Regards
Heinz
