LBNL Report Number
Based upon the years of development and manufacture as well as a documented three and one-half year life test the reliability of the electronic high frequency ballast concept has been established. There are several characteristics that can be used to assess a ballasts performance with respect to cost effectiveness, lamp life and power quality. The higher cost of the electronic ballast is due to the demand exceeding the supply. With more competition in an expanding market the price of ballasts will be significantly reduced.
