Car park
Security more than visibility. Uniformity and light on faces decide how it feels, not the average level.
A car park feels unsafe when the light is uneven, not when it is dim. Dark pockets between light points do more harm than a consistently low but even level, and uniformity is what should be designed first.
The entrance to a multi-storey car park is a problem of its own: the eye arrives from full daylight and needs a much higher level in the ramp than inside, during the day but not at night.
Switches on and off with sunrise and sunset all year, with nobody adjusting timers.
A low level that rises where someone moves, instead of full output all night.
Dark pockets between light points create unease that more lux will not fix.

Target values per SS-EN 12464-1 (indoor) and SS-EN 12464-2 (outdoor). The values are a starting point for the conversation, not a lighting design. The client's own requirements, the geometry of the room and its surfaces decide the outcome.
