One approach employs compact fluorescent lighting sources, normally either table lamps or task lighting systems that can be positioned on the work surface or near the area where a task is performed. In this scenario, designers should consider using single or multiple compact fluorescent lamps housed in a dedicated fixture operated with electronic ballasts. A fixture that is designed exclusively for the use of a compact fluorescent lamp and that is not able to operate any other lighting source is considered to be dedicated to the operation of a compact fluorescent lamp. A wide selection of fixtures is now available, so it should prove relatively easy to locate the exact fixture desired to meet a designer's functional and esthetic criteria. Once a fixture type is selected, inputting photometric data into a point calculation program will determine the number and location of the fixtures required to perform the task.
