default point lights seems wrong after exposure #11577
Description
Bevy version
Main after #11347
What went wrong
Looking at examples, most point lights are set to 150000 lumens, which is more than direct sunlight. Some are even up to 1000000 lumens, which seems an absurd value to set.
The default value of a point light is 800 lumens, which is now useless.
Bevy default values should make sense, and examples should not use values that don't make sense.
