Something to keep an eye on is the direction of light. An obvious issue here is shadowing. Ideally you should avoid placing light sources where they will cast strong shadows. For example if a person walks through a corridor or vestibule and their shadow is cast on the wall beside them, dancing along as they walk, this could be uncomfortable and distracting. Also people should not have to work in their own shadow, this can be annoying and will likely result in complaints.
Less obvious perhaps is the sense in which light ‘flows’ within a space. Perhaps light is washing down a wall from a concealed slot detail, or appears to be flooding in from the ceiling where there is an apparent skylight. Perhaps the light is washing up onto the ceiling, bathing the space in soft, reflected light. The directionality of the light is a significant factor.
