PROBLEM TO BE SOLVED: To provide an illumination lighting device, along with a luminaire, capable of reporting a last stage of lifetime of the luminaire without giving uneasy feeling to neighboring persons and lowering its safety. SOLUTION: The illumination lighting device 1 has a lighting circuit 2 for lighting up a discharge lamp La by supplying lighting-up power to the discharge lamp La, a timer 31 for clocking accumulated operation time of the lighting circuit 2, a lifetime decision unit 32 for setting a plurality of decision time in order to determine a last stage of lifetime of components excluding a light source at a plurality of stages and generating a lifetime decision signal at the corresponding last stage of lifetime whenever the accumulated operation time reaches each decision time, a report unit 4 for performing a report operation reporting the corresponding last stage of lifetime by changing output of the lighting circuit 2 when the lifetime decision signal is input from the lifetime decision unit 32, and a decision time adjustment unit 33 for setting distribution on each decision time between a plurality of illumination lighting devices by making decision time of each last stage of lifetime established on the lifetime decision unit 32 change on a time axis, respectively and individually.
