Crops need light to grow and begin the process of photosynthesis, converting light energy into chemical energy. But the intensity, colour, wavelength and timing of light are all vitally important. Supporting human comfort and productivity as well as plant growth and quality.
If you would like to achieve this based on simple dimming, or even better, by using smart switches instead of smart bulbs, take a look at NASA spinoff Bios Lighting. I use incandescent and halogen everywhere and don't have a problem with color temperature. There is conclusive evidence that blue light does not affect sleep in any way as large as people expect. We're talking about 1 minute on average change in sleep duration. I haven't looked at their list of papers but if they have evidence that blue light affects sleep, why would reducing the blue light coming off your phone/monitor NOT affect sleep? I don't really see why the source of the light would be important to the results.
What is Circadian Lighting and How Does it Work?
If you're interested in HomeAssistant to solve this problem, I wrote a simpler implementation, of using the sunrise/sun position sensor to change scenes for a room's lights. This didn't involve having a Zigbee hub like this post suggests, mostly because all my lights were Hue, or Zigbee-compatible (IKEA-branded Tradfri lights) that were already on my Hue bridge. I would love to find a replacement that supports multiple color temperatures.
Can improve required wavelengths.Circadian lighting tends to focus on increasing blue light exposure, aiming to produce the peak 490nm blue wavelengths produced by the midday sun. This is great for people who live or work in dark spaces that receive little to no natural light. Exposure to these wavelengths during the daytime help to keep the mind and body alert and active.
Circadian lighting is proven to reduce falls in care environments
In fact, daylight is the strongest signal our bodies can receive to help regulate our circadian rhythms and send signals to our brain telling our bodies when to perform different functions. People spend more time indoors than ever before — in fact, a 2001 study by UC Berkley and the EPA reported that we spend 87% of our time indoors . If we think back in human history, we evolved into our natural surroundings – waking with the sun and going to sleep soon after sunset.

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.
I can only turn lights on and off or change the brightness. I'll have to think about getting some ceiling lights with adjustable color temperature whenever I move to a new house. In all honesty, I’ve found it healthier to have fixed color temperature in different rooms, and change what room I’m in throughout the day.
We've worked on similar circadian products, and I have a similar setup at home. IMO, we're getting closer to the time the market is ready. The main learning is to release MVPs and continue to gather feedback from/build a relationship with the core early adopter market. The market is small, probably in the tens of millions of dollars annually, but the right solution is going to be easy to setup/use with a good UI, and priced at a slight premium over other lighting . I wonder how much it would cost to put an gps receiver in every lightbulb? If you can get a gps signal you can get a rough guesstimate of the bulbs location and time and therefore adjust to fit the local circadian rhythm.
I visited a $7500 apartment and it was laughable how they included LEDs that flicker at somewhere around Hz. I just stopped using LEDs until I understand the market more, after already wasting hundreds on failed attempts to find an acceptable LED. For now sticking with warm color temperature incandescent bulbs, which are almost perfect. Orbiting the earth aboard the International Space Station , astronauts experience a sunrise and sunset every 90 minutes — that’s approximately 16 sunrises and sunsets every 24 hours!
He takes a holistic approach to healthcare, incorporating principles of functional medicine and using food as medicine when working with patients. It even remembers the previous setting, so you won’t be startled when turning it on in the middle of the night. Research continues to look at methods for bringing key aspects of daylight indoors and how that might have a beneficial effect on memory recall and other tasks. It is also possible to define a brightness during nightmode, so you can get up without being blinded.
As a biology-first company, BIOS continues to push the envelope in LED lighting solutions for both plants and humans. Circadian rhythms have been observed for centuries in both plants and animals. Whenever I have guests staying over at my place they don't even notice that the lights are changing color throughout the day. The lights get updated every 30 seconds so the changes are very small. In this post we are going to explore how I accomplished this using Home Assistant, Node-RED, and some smart color bulbs.
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.
10+ years after its launch Philips has still never bothered to implement and backup/restore functionality(!!!), so that's a real driver. But in terms of pure functionality it's worked very well to code up a bunch of manual timers and time-of-day-based options on switches. The ESP hosts a page that displays sliders to control the light, which send a websocket command to change the PWM duty cycle. I implemented a lamp temperature to RGB that I found on God knows where, and then had a python script on a raspberry pi to slowly raise brightness and color temperature for sunrise etc by sending directly the websocket commands. I'm inclined to appreciate the technology, yet at the same time I don't think I like it well enough to blow $60/each to replace all my can lights with Hues.
Circadian Lighting: A Bright Idea with Pros and Cons
Just like with flickering LEDs on vehicles, you can't tell right away exactly where the vehicle is. Just having a flickering light on the edge of your peripheral gives you the same alert feeling when an object is moving fast near you, such as a fly. Also, flickering room light probably interferes with rendering of moving objects on a computer / TV screen . HCL is a very niche topic for residential lightning and certainly more expensiv than going with Hue but im betting that high quality HCL will improve our lives especially during winter seasons.
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.
