Until artificial lighting was invented, our main source of lighting came from the sun. People were content to spend their evenings in relative darkness. Today, much of our world is illuminated and though it has been a blessing for years, we are now finding out it may not be the blessing we thought it was. Seems we’ve been taking lumens for granted all this time.
We understand that very strong light will cause irritation or pain, think of staring at a very bright lightbulb, and that low light will cause us strain, think reading in low light.
What we have learned though over time is that the waves of light beaming toward us causes varying effects. Blue wavelengths for instance, are extremely beneficial during the daylight hours. They boost attention, reaction times and can act as a mood stabilizer. Blue wavelengths at night though presents a problem. The problem of blue light is more known with mobile phones and computer screens, and manufacturers are combating that with a “night mode” that removes blue light from the screen. However, as LED’s become the norm blue light waves are more present than ever, increasing our exposure after sundown, when we least need them.
A phototoxic effect
In a recent French study, the French Health Authority has warned of the “phototoxic effects” of blue light short-term high intensity exposure. The study claims that there is an increased risk of age-related macular degeneration after continuous exposure to lower-intensity sources like electronic devices and LED lighting, to name a couple. Blue light will also affect the circadian rhythm of people who tend to stay up later than normal (Your circadian rhythm keeps your internal ‘clock’ aligned with the rise and setting of the sun). It will also cause your body to reduce production of melatonin, a hormone that influences circadian rhythms at night and needed to relax and get a good night’s rest.
While light of any kind can affect and suppress secretion of melatonin, blue light at night does this with quite a bit more power. Its effect can shift circadian rhythms by as much as 3 hours.
Leading a healthier life, letting blue light go as the day passes
Personalized lighting is the ability to adjust lighting in your home to any event, time, temperature, architectural feature by putting the smart technology in the lighting system and using a central panel to control the light wavelengths.
Color shifting is a major advantage of this type of home lighting design. Think of it like adjusting your mobile phone to nighttime viewing. You will receive less harmful wavelengths while being unaffected by the light itself so seeing your surroundings remains virtually the same. Color shifting also follows your circadian rhythm to give you that ‘warm’ lighting when needed the most, at night.
This smart lighting design moves toward a ‘human-centric’ circadian light response to your environment, rather than leaving you with no options to control the blue light wavelengths as the day passes.
Human centric lighting brings natural lighting indoors, designed to stimulate your mind during daytime to maximize productivity while dimming any damaging blue light in the evening to allow for a better night’s rest.
It’s a fact that human centric lighting is the biggest breakthrough in residential lighting since the dimmer was invented by Lutron in 1959. Controlling the ability to reduce damaging light for you and your family is simply one of the best residential technologies to have come along in a while!
