# Objective Another step in the migration to required components: lights! Note that this does not include `EnvironmentMapLight` or reflection probes yet, because their API hasn't been fully chosen yet. ## Solution As per the [selected proposals](https://hackmd.io/@bevy/required_components/%2FLLnzwz9XTxiD7i2jiUXkJg): - Deprecate `PointLightBundle` in favor of the `PointLight` component - Deprecate `SpotLightBundle` in favor of the `PointLight` component - Deprecate `DirectionalLightBundle` in favor of the `DirectionalLight` component ## Testing I ran some examples with lights. --- ## Migration Guide `PointLightBundle`, `SpotLightBundle`, and `DirectionalLightBundle` have been deprecated. Use the `PointLight`, `SpotLight`, and `DirectionalLight` components instead. Adding them will now insert the other components required by them automatically.
