When I record with flash on my phone the screen on my phone shows it flashing red and green and it sometimes loses focus. This does not happen when recording any other parts of the led light

I’m not convinced it’s a light. To me it looks like the zooming is changing angles of light or something like a prism effect. The concave ring may collect light similar to a mirror; but squish a windows worth of light into a small point.

Put something up next to the light that will allow the camera to focus. Stick a piece of paper to the ceiling. Maybe get some more light shining up there to see if focus happens normally. There’s not a lot of light, it will have a harder time focusing.
