In this study we simulate the illuminance and efficiency of four different types of reflector LED and fluorescent light sources for interior illumination. According to our calculation results of the examination of simulations and real situations, we find that the LEDs do perform better than fluorescent lights. We also consider the problems of glare with LED lights by utilizing a diffuser to protect the eyes. We are assured of the potential advantages of LED lighting in the future.
