Yes **** for brains, in fact yesterday 5pm I noticed that the lights were on before I entered, yes I think people have been complaining about walking into dark rooms at night.
Went again this morning at 10am lights on during the day, they have turned the sensors off and the lights now remain on even in daylight.
So that proves they are a failure in the real world.
But this technology works OK with the sinks, as they detect when your hand is under the tap and it starts dispensing warm water, which you only really want on once your hand is in the sink unlike lights which people prefer to be on before they enter the room rather than come on after you enter it with a delay.
