Using "Layered Lighting" in classrooms

For classrooms that have no windows, or rooms that will be heavily used after dark, a more appealing method of lighting uses several different types of lighting fixtures... in "layers".
The photo below illustrates three different fixture types being used to do much more than just provide adequate task light on the desks.



"Direct" concealed PAR lamps give "punch" light on the desks, but unfortunately also produce harsh shadows under a writing hand.
"Indirect/Direct pendant fluorescent fixtures both send shadow-free light down on the desks, and also illuminate the ceiling.
Fluorescent wall lights accent the texture of the walls and add bounced shadow-free light on the desks nearest the walls.
