  • March 2nd, 2023 Blue light has a dark side

    Taken from Harvard Health Publishing Published July 7th, 2020 What is blue light? The effect blue light has on your sleep and more. Although it is environmentally friendly, blue light can affect your sleep and potentially cause disease. Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in (relative) darkness. Now, in much of the world, evenings are illuminated, and […]

  • May 3rd, 2022 Does LED light harm babies?

    Since the development of the light bulb 142 years ago, human’s natural exposure to light has changed. In an increasingly digital world, more and more people are working in offices, in front of computer screens. In 2018 it was estimated that Brits spend 90% of their time inside, which equates to a whopping 22 hours a day. Fast forward to a world ‘post pandemic’, where we are living under more […]

  • February 2nd, 2022 Blue light bad, red light good!

    Light from the sun plays a key role in powering all life on earth, even in the makeup of our cells. We have talked a great deal about how an imbalance of blue can be extremely detrimental to our sleep/wake cycle and many aspects of our physical and mental wellbeing, actually impacting our bodies at a cellular level (read more here: “Your Lightbulb Moment- What’s so Bad about Blue?”)…but what […]

  • January 5th, 2022 Resolutions for Wellbeing

    The start of a New Year can be a really exciting time. You may feel re-energised or refreshed for a ‘new start’, particularly if you had a chance to rest over the festive period  (many lines of work allow for staff to have at least a few days off for Christmas and New Year). Even if you worked at Christmas or New Year, you may still feel positive about the […]

  • November 22nd, 2021 SAD Syndrome and RAY

    When you think of winter, what do you think about? Frost on the ground in the mornings? Wrapping up warm to leave the house? Snow? The drop in temperature might be the first thing that comes to mind for most people, but the impending months of feeling low is the reality for some. It’s not the most positive sounding disorder, but SAD syndrome is very real, and is how the […]

  • October 6th, 2021 Excess blue light can’t affect my gut micro bacteria… can it?

    It may be something that you’ve not thought about before. If light impacts sleep and sleep impacts the balance in the gut, as research is finding, it’s a fairly simple leap and may go some way to explaining the propensity towards weight gain, obesity and even diabetes amongst those who suffer with insomnia or work night shifts. Here’s how, why and what you can do to address it.  Circadian rhythm […]

  • October 5th, 2021 Human-Centric Lighting VS Circadian Friendly Healthy Light

    Mainstream human-centric lighting is based around changing colour temperatures throughout the day in an effort to persuade the body’s Circadian rhythm while indoors that it is experiencing natural sunlight. Unfortunately mainstream human-centric lighting currently uses conventional LED, which is built around blue chip at its source. This means they contain a significant spike of excess high frequency blue, in proportions that would never occur in natural sunlight. Typical colour changing […]

  • June 24th, 2021 The other pandemic – and how to avoid it

    Amidst the Corona pandemic, another pandemic is unfolding and it’s impacting our children most of all. It’s referred to as ‘the myopia pandemic’ and it essentially means that 50% of young people in Europe today are short-sighted, according to Caroline Klaver MD in the Netherlands. (That’s half! Up from 10% naturally occurring short-sightedness in young people less than 20 years ago). Dr Klaver isn’t the only one concerned – research […]

  • March 12th, 2021 A new RAY of hope for blue light concerns in the home

    Parenting expert, Sue Atkins, has been concerned about all aspects of children’s development for many years, but one specific issue has caught her attention recently as technology and scientific discoveries reveal a cascade of concerns: “We are all spending more and more time indoors and on technology.” Exposure to excess screen times and poor quality indoor light is impacting our health and wellbeing – from sleep deficits to anxiety and […]

  • March 4th, 2021 Blue Light is more than just a sleep inhibitor, it’s the keystone

    There’s so much buzz about blue light right now, it’s clear that it is a major influencer for the mental and physical health of everyone. Many of us are getting to grips with the fact that too much blue will overstimulate our systems, by supressing the production of melatonin (the hormone that helps us to relax and rejuvenate) and may have come across the term Circadian rhythm – the daily […]

  • December 15th, 2020 What is Full Spectrum phosphor overlay in an LED lightbulb and why should I care?

    Did you know that virtually all existing LED lights are actually blue? They are built around a light source in the form of a small chip of semi-conductor material that releases energy in the form of photons. These photons are emitted as extremely bright blue light. This is then covered with a layer of phosphor that makes the light we actually see appear white or yellow. The resulting light is […]

  • August 27th, 2020 Your lightbulb moment – what’s so bad about blue?

    You may have heard that blue light is not good for us. It triggers a ‘good morning’ response in our brain, meaning we can never truly switch off. But very few of us realise that it’s the baseline in almost every light we use. It’s not just phones and computer or television screens – LED light has traditionally used blue light as its source, too (with a special coating to […]

  • February 24th, 2020 LED: The flicker factor

    Why you need to look twice at the lights in your home We’ve all seen a flickering lamp. But did you know that all artificial light flickers – whether you can see it or not?
