Patient room
The same set of luminaires has to handle reading light, examination and night rounds. The range is 5 to 1000 lux in a single room.
A patient room is both a home and a workplace, and the two have opposing requirements. The patient lies down looking up, the staff stand and need to see. Glare is therefore judged lying down, not from the doorway.
The night scene is the hardest and the most important: enough for a round, low enough not to wake anyone, and directed downwards so nothing shines into the eyes of someone lying down.
A low level near the floor, enough for staff but leaving the patient undisturbed.
The patient controls their own light without affecting their neighbour.
1000 lux and Ra 90 on demand, not as the base level.
