How does the effect work?

Lighting to desks is uneven - lights create reflection-glare - staff create shadows where they work.

Is 'category 2' lighting a legal requirement?  CIBSE says:

"The term 'category 2' is no longer used by the CIBSE. It was used to describe a particular design of luminaire (light fitting) that could be employed to prevent reflections of the luminaire on the display screen. Unfortunately, in doing so, these luminaires can produce a gloomy environment if used on their own without consideration of surface reflectances. In most offices, particularly where modern computers with bright screens are used, such reflections are not likely to occur and therefore it is not necessary to specify this type of luminaire." The Chartered Institute of Building Services Engineers (CIBSE)
