Abstract
If there is optical contact between the phosphor coating and the glass wall of a fluorescent lamp, some of the light will be lost by total internal reflections within the glass wall. This loss decreases the wall efficiency. The theory of this optical contact light loss and a technique for measuring it are described by the authors.
