Abstract
A ballast including a single sense element and a single controller for mulitple lamp operation. The ballast avoids the need for separate feedpaths for sensing individual lamp conditions and/or the need for separate controllers for controlling the individual lamp conditions. Consequently, the ballast scheme avoids the use of expensive components (e.g. controllers and chokes) and minimizes the number of components required in order to operate multiple lamps.
