It is from a line of text in the file:
/sys/devices/system/fl_tps6116x/fl_tps6116x0/fl_intensity
That is a virtual file whose content is dynamically generated by a device driver each time you read from it. In this case, it shows the current intensity level of the FrontLight LEDs.
See this post for more info:

In those examples, the
cat command is used to read the current intensity (brightness) value, and the
echo command is used to write a new value.
