Abstract
The invention comprises a fluorescent lamp system wherein an ultraviolet producing discharge tube contains no phosphor internal to the tube. Rather an insert or sleeve physically distinct from the tube includes a phosphor. The layer insert or sleeve further includes an ultraviolet filter, preferably in the form of an ultraviolet reflective/visible light transmissive layer positioned to reflect ultraviolet energy that is not converted to visible light on a previous pass through the phosphor, back toward the phosphor. It has many embodiments.
