This research is a study on the quality analysis and comparison of illumination of the indoor stadium, in conjunction with natural light. A case study of the rajamangala University of technology Lanna Chiang Rai current Stadium inside the building highbay is installed.metal halide lamp 400 w by measurement of luminance from the metal tube 400 Watts and simulated activities HA luminance of metal tube, 400-watt bulb like Haru, diode, light emitting 325 Watts, together with natural light and using the program DIALux to be used in determining the light and sat.Ongsawang of the building of the stadium in rajamangala University of technology Lanna Chiang Rai. Simulation of the brightness of the indoor stadium consists of volleyball and Badminton Court. From the experimental results. Indoor sports stadium lights, bulbs, light-emitting diode. 325 w have a brightness luminance and uniformity of light stadium is better than the metal halide lamp 400-Watt
