Prompt: Change the indoor lighting to nighttime, with the indoor environment illuminated by indoor lights.

This post from ComfyUI's Twitter account demonstrates a prompt used within the ComfyUI node-based image generation system to modify lighting in generated scenes. The prompt instructs the AI to render an indoor environment with nighttime conditions where artificial indoor lighting serves as the primary illumination source. This is an example of how specific descriptive prompts can be used to control environmental and lighting characteristics in AI image generation workflows.
