There’s lots of jargon when it comes to ergonomic lighting, and unless you’re a specialist it will probably sound confusing to you. In general, on a clear day outside lighting is around 10,000 lux, by a window inside the light goes down to 1,000 lux.
Roughly, it is recommended to have 100-300 lux in a room where you don’t perform concentrated visual tasks, like the hallway or the bedroom, whereas you’ll need 500-800 lux if you’re reading or drawing, bumping it up to 800-1,700 lux for specific concentration tasks.
Having the ability to change the lighting of a room is important too, in a dining room you can switch from an active area during the day to a relaxing space at night. Children’s bedrooms will also need to be versatile as they will often both sleep and study in their rooms, so ambient and task lighting is needed.
