Lighting and Human Health Impact

Lighting plays a key role in the human experience. Research continues to show the impact on human health, overall sense of well-being, comfort, and performance. Lighting designed to leverage this relationship is termed Human-Centric Lighting.


Understanding Human Centric Lighting

Human Centric Lighting (HCL) refers to lighting designed not only to illuminate a space, but also consider the impact on individuals within that space.  The human body has natural cycles, referred to as Circadian Rhythms and light plays a key role in regulating this cycle.  Disrupting this cycle can impact a person’s:


●        Concentration levels

●        Memory

●        Sleep patterns

●        Vision

●        Health

●        Productivity


Lighting Plays Key Role in Health

In human history, our natural environment provided the healthy lighting our bodies needed.  Think of how the sun provides a warm glow low in the sky at sunrise and sunset, and then strong, bright light mid-day.   This natural, daily rise and fall of the sun supported our natural circadian rhythm, including natural triggers like the production of melatonin, which helps the body fall asleep.


Now compare that to dull, overhead fluorescent lighting we experience all day. Then add the lighting and stimulation in front of us from our phone, TV and computer screen well after the sun has set.  This constant, poor lighting may illuminate a space, but can cause a lack of productivity, sleep problems, and other health issues.



LumaFilm’s Thin, Flexible LED Offers a Solutions to HCL

LEDs combined with controls allow lighting designers the tools to determine when lights come on, adjust the color temperature throughout the day, and soften the lighting in the evening to provide healthy lighting mimicking the natural light our body needs.


LumaFilm’s thin, flexible product ideally solves multiple problems:

●        Diffuse, even lighting allows back lighting of thin faux windows, creating a virtual indoor space to provide healthy lighting in hallways, hospital rooms and care facilities without obtrusive frames, meeting ADA requirements

●        Easy installation makes it simple to add healthy lighting as a backlit skylight to bring the outdoors to a conference room or basement meeting space.

●        The thin design, adaptable to virtually any size, allows installation in modular office furniture providing the ability to direct the light horizontally, which studies show is key for how our bodies may react to certain spectrums. 

●        LumaFilm’s Dynamic White product easily adjusts from 2700K to 500K, allowing tuned spectrums throughout the day for productivity just like our sun.
