4.5. Corridor lighting 100% during the day and 30% at night

In the corridor, we have some switches to operate the corridor lighting. If we operate such a switch between 07:00 and 22:00, then the corridor lighting will adjust between 0% and 100%. At night, however, the same switch will adjust the corridor lighting between 0% and 30%. At night, there only needs to be enough light to get through the corridor safely. If, however, we want to clean the corridor during the day, then the lights must be at 100% so we can see adequately.
