Lighting is an important aspect of your home, and over and above general lighting with the right plan you can fundamentally improve your home's practicality, ambience and aesthetics.
Standard lighting is your very basic lighting that helps you see when it's dark. This lighting is fairly standard - ceiling unit plus bedside lamp type plan.Practical lighting (or task lighting) is lighting related to a specific function. Ambient lighting (accent or aesthetic lighting) can be used to highlight specific things (like paintings) or create moods (eg low coloured lights) or simply add depth to the general lighting by creating light from all angles instead of one.
