Constants

LUMENS_PER_HALOGEN_WATTS

The conversion factor used to determine how many lumens a typical halogen light of a given wattage produces.

LUMENS_PER_INCANDESCENT_WATTS

The conversion factor used to determine how many lumens a typical incandescent light of a given wattage produces.

LUMENS_PER_LED_WATTS

The conversion factor used to determine how many lumens a typical LED light of a given wattage produces.

VERY_LARGE_CINEMA_LIGHT

1,000,000 lumens is a very large “cinema light” capable of registering brightly at Bevy’s default bevy_camera::Exposure::BLENDER exposure level. For “indoor lighting” with a lower exposure, this would be way too bright.
