Horizontal illuminance is an important indicator, which shows the resources of the light climate of each region. Meticulous consideration of the light-climate data allows us to develop graphs of diffuse and global illuminance (ED and EG) and go to the territorial norms of daylight spaces at the modern level. Measurements of horizontal illuminance in Vietnam are not available; therefore, the calculation of the determination horizontal illuminance from solar radiation by light equivalents using the values of the luminous efficacy is widely used now. The paper contains calculation of the luminous efficacy for Vietnam, the results are graphs of horizontal illuminance for Ho Chi Minh. Comparative analysis with horizontal natural illuminance of Moscow shows a high level and uniform distribution of outdoor illuminance in the tropical sky in Vietnam. The maximum values of ED and EG for Ho Chi Minh City are 42.01 Klux and 87.17 Klux; for Moscow these values are equal to 28.3 Klux and 53.1 Klux, respectively. In addition, the levels of illuminance in the winter months in Ho Chi Minh are much higher than in Moscow, which is explained by the latitudinal difference in the location of these cities and the corresponding movement of the Sun.
