What is the brightness standard of elevator car?

There is no such provision for the time being. Can only rely on property management and elevator maintenance units.

Property management: pay attention to property image and create a good environment. First-class service, customer first.

Elevator maintenance unit: With the property management system, the cost is not a problem. Self-check the safety and use of elevators and deal with potential problems in time. First-class service, customer first.
