The Many Applications and Benefits of Human Centric Lighting

Hear from our experts on Everything LED Lighting

Human Centric Lighting (HCL) has made leaps and bounds in innovation thanks to the help of LED lights. In the past, we have covered the specific benefits of HCL in hospitals, schools, offices and more. Today we are going to take a look at the variety of applications HCL has, as well as its overarching benefits!

HCL Applications

Homes and Hospitals

One of the most common applications for HCL is in homes and hospitals. These are so popular because they are used to improve sleep, which is something patients in hospitals struggle to get, as well as people in their homes. LED HCL has such a positive impact on sleep cycles because it signals the body to produce melatonin, a hormone released to induce sleep.

Advanced LED HCL systems are tunable and can mimic natural sunlight throughout the day, from dawn until dusk. These systems are often used in hospitals and nursing homes to help relieve stress and anxiety as well as improve sleep.


Another HCL application we have discussed in the past is in classrooms. LED HCL has been proven to increase productivity in the classroom when using cooler, whiter light, and encourage relaxation during rest or nap periods with warmer, dimmer light.

Office Space

Similarly to schools, LEDs have improved focus in office spaces. Studies have even shown HCL in office settings can increase the employer’s bottom line with improved productivity and reduced sick days!


A new and interesting use for HCL is on airplanes! HCL can provide a better flight experience for those traveling internationally. The lighting can be customized for the flight activities, such as boarding, meal times, and sleep, and also to alert and wake passengers as they prepare for landing.

HCL Overarching Benefits

Overall, LED driven HCL can have positive impacts on your life, or the lives of your patients, students, employees and more. Lighting plays such a key role in our biological circadian rhythms, making proper lighting important. Looking at bright blue phone screens or TVs directly before bed can upset these rhythms, making it difficult to fall or stay asleep. Dim, flickering fluorescent lighting can cause procrastination and unrest in employees.
