Lighting For Video Display Terminals
VDTs (also referred to as Cathode Ray Tubes or CRTs) are common in offices. Improper lighting can result in worker discomfort and fatigue. 

Factors to weigh in determining VDT lighting requirements are the light generated by the screen itself, work areas adjacent to the screen, keyboard lighting, and other tasks performed in the same space. 

If your employees use VDTs for a significant portion of their time, it would be advisable to consult a lighting specialist.
