HCL (Human-Centric Lighting)

Human-Centric Lighting (HCL) is a lighting approach designed to align with our natural biological rhythms, such as the sleep-wake cycle. By mimicking the changes in natural daylight—brighter, cooler light during the day, and warmer, dimmer light in the evening—HCL helps improve alertness, mood, and overall well-being. It considers how light affects our health and productivity, creating indoor environments that support our body's needs throughout the day. Essentially, HCL uses smart lighting to enhance comfort, focus, and health by harmonizing artificial light with our natural circadian rhythms.
