In modern society, people spend 90% of their time indoors, but in many cases, indoor lighting is not enough. People stay in a closed room for a long time, which will cause adverse effects on people’s body and mind, such as biological clock disturbance and depression. Pesetech introduces a new generation of intelligent artificial skylights that simulate a realistic blue sky that looks like a real skylight with infinite depth. The ultra-wide 1800K-10000K color temperature can also simulate sunrise and sunset, simulate all-day changes in sky color temperature (HCL lighting), enhance your circadian rhythm, and enhance your cognitive skills and well-being.
