Kessil light started flashing during ramp down. Help!

[Tomorrow's Waters]

Bought two Kessil A360WE lights brand new from BRS 3.5 years ago. Both lights are connected to the same controller in series. The light in the video has begun flashing like crazy during ramp down. The other works perfectly.

Anyone experience this before? Possible solutions?
TIA!

I suggest you talk to Kessil customer service.

Also, while the lights are connected together, they are in parallel not series.
