A system, method, and apparatus for gathering operating information from a lighting product. The lighting product includes an embedded persistent memory unit and processor configured to store data operating parameters in the memory unit. The memory unit may be accessed up through and after end-of-life of the lighting product. The memory unit may be physically removable, or may be accessible via a wired or wireless interface such as an NFC tag. The lighting product memory unit is accessed at an in-store kiosk by plugging the lighting product into a socket or swiping the lighting product with an NFC tag reader. Data recovered from the memory unit is used to select and display a range of suitable replacement lighting products from a database.
