M18 blink

It’s hard to see from the video - but there’s a noticeable lack of brightness (I have a Vivicine M18, I know what to compare with), white looks like yellow - it seems to me that the power supply does not work at full power, and when it tries to reach full capacity, it can't and flicker appears. 1m26s - blink 3m43s - blink 4m17s - blink 7m10s - blink 7m55s - blink
