b) controlling lighting non-patient care zone that comprises a plurality of tunable and/or non-tunable lighting components; wherein said lighting in said non-patient care zone delivers a M/P ratio less than 0.5 in the evening and night at an illuminance of 75 lux on a vertical plane as measured at eye level; and
c) controlling lighting in a staff zone that comprises a plurality of tunable and/or non-tunable lighting components; wherein said lighting in said staff zone delivers a M/P ratio of greater than 0.7 at an illuminance of 75 lux on a vertical plane as measured at eye level.
