The aim of this paper is to facilitate development of testing and certification procedures that will allow the qualification of pump or source devices, pumped conversion materials/remote phosphors and reflective materials, independently. Then, qualification of the remote phosphor system (pump + conversion material + mixing chamber material, if applicable), if it meets certain criteria, does not require testing of each combination of pump device, conversion material and mixing chamber material. This can simplify the testing required to qualify for ENERGY STAR? for instance. Below, important criteria affecting lumen maintenance of the various components, variations to be expected in remote phosphor device design, and testing procedures are described.
