Verderber, R R

The real energy savings that can be obtained with electronically ballasted fluorescent lamps compared to lamps operated with standard core-coil ballasts exceeds 40%. This savings is realized because of improvement in the intrinsic efficiency (20 to 25%) of the electronic ballast, and because of the manner a lighting designer can best meet the proper light level, for a lighting design. The astute lighting designer can reduce energy use by over 70% in an appropriate space with this new tool by the use of natural illumination (daylighting). Together with these gains are improvements in the comfort and quality of the illumination. Fluoresent lamps operated with some electronic ballasts exhibit no flicker and, in addition, provide each lighting fixture with the possibility of tuning its output to the needs of the occupant. These latter techniques should contribute to the occupants' productivity.
