On the other hand, going with Phillips Hue or similar will lock me into that ecosystem - which also dictates which lights and switches I could use. While I haven’t gotten my lights set up like this, I do use home assistant, just like the author and it is simply amazing. For things like this, the setup can get quite complex, but the main benefit is that it provides a unified interface to any connected device in your home.
Correlated color temperature relates to how ‘warm’ or ‘cold’ white light is when perceived by the eyes. Red and yellow tones are perceived as ‘warm’ while blue and white are perceived as ‘cold.’ These variations are then conveyed inversely in degrees Kelvin, with warmer temperatures being lower and cooler temperatures being higher. There are light bulbs that will automatically decrease light temperature when they are dimmed (e.g. Phillips with "Warm Glow").
What is Circadian Lighting and How Does it Work?
Then our team of professionalshelp you select lighting from light sources with the appropriate spectrum, color temperature, and brightness for each area. Wellness is becoming more of a central theme in the design and a critical part of each of our daily routines. We know that subtle changes in lifestyle can allow us to feel better, which has a significant ripple effect on our overall feelings of well-being. Circadian lighting is one way we can design better spaces to create subtle, yet meaningful change in our lifestyle.
This lighting is best used in bedrooms, living rooms, or other relaxing spaces. The concept of circadian lighting does have the potential to support a healthier circadian rhythm, however this technology is still being developed. The following are current pros and cons of incorporating circadian lighting technology in your home. I have automations set up to dim the lights around sunset gradually over the course of 30 minutes, which also automatically adjusts the color temperature. Circadian lighting—lighting that changes color to promote sleep at night and energy during the day—is the future.
Circadian lighting is proven to reduce falls in care environments
I never notice it happening, but at some point realise I can't see my keyboard very well if using the laptop etc. There is more to light than meets the eye — a lot more, in fact. While light enables us to see our world in vivid color and stunning detail, we have learned that light also regulates the ‘internal clock’ in our bodies that governs our circadian rhythms that makes us alert during the day and sleepy at night. BIOS understands the fundamental science behind circadian lighting and continues to innovate, finding new ways to improve the quality of the spaces we occupy every day on a biological level. So, this perceived change from very warm to very cool light that is commonly talked about and used as a marketing feature, is actually not an accurate reflection of what is happening in the sky throughout the day.

From new tech innovations, the latest projects, and insights in healthcare, hospitality, or education , it's your one-stop shop to stay up to date on industry trends. The director of the Center for Human Sleep Science at the University of California, Berkeley suggested that we are in the middle of a ‘catastrophic sleep-loss epidemic’ and even that ‘sleep should be prescribed’. According to the NHS, regular poor sleep actually presents serious health risks, such as obesity, heart disease, diabetes, and a shortened life expectancy. Often a simple plastic screw behind the plate that you can tweak. I can understand night being dark when you live in the middle of nowhere.
Improved Sleep Cycles
This way you could disable it in one room without disabling the entire house. Michael Jelly, 27, a British app founder who divides his time between San Francisco and London, became a circadian hacker a few years ago after struggling with daytime sluggishness. Jelly bought a Whoop strap that tracks his overnight heart rate, blood oxygenation, breathing rate, skin temperature and sleep cycles, then coded his own app from the data to analyse what he perceived to be a weekly “accumulated sleep debt”. For all their absence of erotic charm, my latest health gadgets – the light-blocking night glasses and a dome-shaped morning light lamp that turns my face ghostly white – have seen me through five long winters.
Circadian disruption (manifested as depression, agitation, nighttime wandering, increased daytime fatigue, loss of cognitive ability, etc.) can happen in most cases. Another industry that can benefit considerably from circadian lighting and sophisticated lighting algorithms is vertical farming. The absence of natural light in this environment means granular control of artificial light is essential to create the best conditions for crops to flourish. Light is the biggest synchroniser of our 24hour internal body clock; natural light is the best way to keep your body clock in sync.
Node-RED Flow
Some hi-CRI bulbs even lower the colour temperature to mimic incandescents when dimmed. I have a Hue setup at home and I do something like this, but hackier through an iPhone app I set up 4-5 years ago (it hasn't broken yet and I haven't touched it); I believe there are more elegant software solutions these days. Very nice, especially this time of year when it gets dark while I'm still working. I wish that Hue and LIFX would also make a physical adjustment switch/knob for color temperature.
I am testing atm theory that cycling environment color temperature from cold to warm and back to cold in 90 seconds boost your performance in monotonic work by at least 15%. There is some old publication somewhere accoring to my sources, but I could not find it. One thing I really like about my current system is that it still works without any internet or network connection, or if my Home Assistant server is offline. I think this would be a bit more complicated with controllable ceiling lights, but it could probably be done via Zigbee binding and a Zigbee wall switch.
Even during new moon with a cloudy sky there is usually so much light pollution that it is never completely dark. I mean if your bathroom windows were on the other side of the house or had no street lights shining into them, you wouldn't be able to see... You could have saved all this trouble and just used time-tested incandescent bulbs.
With circadian lighting, this progression is recreated in your home through the use of high-tech adjustable LED Smart bulbs. These Smart bulbs perform on an expensive Smart lighting system with a timer set to increase the brightness and blue light as the day progresses, peaking around midday, and then reducing into the evening. Spectrally optimized LEDs, on the other hand, take a very different approach. They target melanopsin, which is a photopigment in the eye that sends signals to our brain to help regulate our internal clock and a variety of biological functions every day.
Awake all night and ravenous at 4.30am through those exhausting months, I found that every part of me was singing from a different hymn sheet . T’s 8.30pm on a gloomy November evening and I’m sitting on the sofa under a tartan blanket and wearing a pair of orange-lensed specs. We work with owners, operators and designers of care environments to bring the benefits of circadian-supportive care to existing and new properties. Connected sensor networks can monitor any variables you may require, such as the noise level in a room. If a class has become loud and disruptive, the lighting can react in real-time to subtly adjust the ambience, resulting in a calming effect.
Stay tuned for our next blog that dives deeper into how different light sources affect you mentally and physically and how to use them to design a healthy happy home. Ideally, we should all sleep in complete darkness, however homes rarely support this essential component for optimal sleep. TheSleep Foundationemphasizes the significance of darkness when sleeping and the negative impacts of light during slumber hours which result in fragmented sleep, eye strain, weight gain, and even cancer risks. If you have a HomeKit set up, I encourage you to also look into adaptive lighting.
Circadian Lighting: A Bright Idea with Pros and Cons
Melanopsin is most sensitive to 490nm – which translates to the “sky-blue” region of the visible spectrum – and transmits non-visual information to the master clock in our brains. Traditional white LEDs usually have a blue peak around 450nm which means they are not as effective at targeting melanopsin or providing a circadian signal to the brain . This means that any indoor space with traditional white light — tunable or not — does not provide the important sky-blue signal our bodies need. Is a term that has gained popularity in recent years – you may have also heard it referred to as ‘human-centric lighting’ or ‘tunable lighting’ or mentioned in the context of biophilia. While these are more often used as buzzwords, circadian lighting is an area of real research, science, and innovation. You could go a step further and make an input_boolean for every room you are doing circadian lighting in.
Sometimes, feeling better just requires stepping into the light. If you're up to date on wellness research, you know that light has a huge impact on our body's internal clock, or circadian rhythm, and an impact on our health in turn. The more we learn about this interplay, the more we see that light is something we should not only be thinking about all day long; it's worth designing our homes around. Daylight provides bright, blue-rich light in the early morning to deliver an alerting signal as we wake up – but exposure to the same light at night can keep you up at night and throw off your game the next day. In the early evening, the setting sun provides a warm, low-level light to cue our bodies for a period of rest.
