Does anyone else own Came-TV Boltzen lights? I own the 55w bi-color version and i've been noticing that after leaving them on for a while (about 3 hours) it appears the the brightness level (left at 25% will start rising to a much higher number). I'm plugging them in directly to AC power, 3200K.
 
Hiya. Is this what you mean: https://youtu.be/4KN8CU0TBZA

I sent this video to CAME and they've responded by saying I need to replace the brightness potentiometer.
They are sending a new pot and they made two video clips for me showing how to disassemble the light and fit the pot.
There's two large gauge power wires that need to be desoldered in order to reach inside, but the pot itself fits onto the PCB via a multipin PCB plug so that's good news at least.

They've confirmed that it won't invalidate my warranty (I bought the light directly from CAME via AliExpress)
 
Sorry I forgot I posted this. Mine changes but not as aparent as the video clip. It can take a few hours of it being on and then all of a suddent I will notice that it has shifted 25%

I would probably break the unit if I try to solder myself but good to know that they are aware of the issue.
