# Objective Fix https://github.com/bevyengine/bevy/issues/11577. ## Solution Fix the examples, add a few constants to make setting light values easier, and change the default lighting settings to be more realistic. (Now designed for an overcast day instead of an indoor environment) --- I did not include any example-related changes in here. ## Changelogs (not including breaking changes) ### bevy_pbr - Added `light_consts` module (included in prelude), which contains common lux and lumen values for lights. - Added `AmbientLight::NONE` constant, which is an ambient light with a brightness of 0. - Added non-EV100 variants for `ExposureSettings`'s EV100 constants, which allow easier construction of an `ExposureSettings` from a EV100 constant. ## Breaking changes ### bevy_pbr The several default lighting values were changed: - `PointLight`'s default `intensity` is now `2000.0` - `SpotLight`'s default `intensity` is now `2000.0` - `DirectionalLight`'s default `illuminance` is now `light_consts::lux::OVERCAST_DAY` (`1000.`) - `AmbientLight`'s default `brightness` is now `20.0`
