The document proposes a Real Lighting Network System to address the lack of access to direct sunlight experienced by many urban dwellings. It would use light sensors to detect outdoor light levels which would then wirelessly transmit that data to adjust indoor lighting to closely match the intensity and temperature of natural light. This system aims to help prevent health issues associated with lack of sunlight like vitamin D deficiency, seasonal affective disorder, and increased risk of certain diseases by allowing indoor lighting to better simulate outdoor light conditions.
