There is no way a fluorescent lamp in any state can affect a

Aren't garage door openers RF in IR? What good would a line of sight device
do when your on the other side of the door?

Read the original post carefully. The IR is used to communicate between the
opener (mounted over the door instead of in the middle of the room) and the
light (mounted somewhere in the room).

The opener remote device used from outside the door within a car is
a radio device. The safety eye devices that are placed at the lower
half of the door closure are optical make/break devices.
