I have two Z-100 5K lights that I bought at auction.
One has Ver 16 and the other with Ver 22.
When I put them in Test mode Ver 16 light slowly brightens then dims while Ver 22 light stays lit and doesn't dim.
Is this normal behavior for both?
All settings are identical in both and both have been reset to factory settings.
Also, can the software version on these be upgraded by the end user?
