In our constantly evolving society, technology has become a vital part of life. We use technology for work, studies, entertainment and more, and as a result we are endlessly emitting blue light.
What is blue light?
Blue light is emitted from the sun, electronic devices such as phones and TV’s, and lighting products. Blue light has positive effects, such as boosting mood and attention, which is great during the day, however this can have adverse effects at night, as you don't want to experience alertness when trying to sleep. That is why low blue light options are great.
Who is affected by blue light?
Blue light can affect anyone, children, adolescents and adults.
How does blue light affect me?
Blue light can affect both your physical and mental wellbeing. Exposure to blue light can suppress melatonin (the hormone that makes you tired), which can lead to tiredness during the day and mood disorders. Blue light exposure can also cause eye issues, such as retina damage and eye strain.
A leading organisation in the health sector, UC Davis Health, has done research demonstrating this.
How to prevent blue light intake?
There are small things you can do daily to limit your amount of blue light exposure. These include:
Limiting screen time, including TV’s, laptops, tablets and phones
Switching your smartphone to low blue light mode
Changing old lights to blue light reducing lighting around the home, especially in areas you’re around before sleeping
Wearing blue light reducing glasses
These changes are great to do throughout the day, but are most important to put into practice the few hours prior to sleeping, as this is when blue light can be the most damaging.
Research done by Apple, Philips and Harvard University suggests that enough blue light can be harmful to eyes. They also recommend the simple tips above for preventing blue light intake.
Eye sensitivity to light?
Blue light exposure can cause issues including:
- Retina damage
- Eye strain
- Dry and irritated eyes
To limit these issues, you can wear blue light reducing glasses when looking at screens and change old blue light emitting downlights to low blue light downlights.
The Royal Society, a New Zealand independent, statutory not-for-profit’s research backs this up.
How to get more deep sleep?
Getting quality, deep can:
- Improve your mood
- Boost immune systems
- Create a healthy circadian rhythm (body clock)
Reducing your blue light intake before bed can help you sleep better, deeper and longer. This can be achieved by limiting screen time, turning devices to low blue light mode, and replacing the lights in your bedroom and areas you spend time in prior to sleeping to blue light reduction downlights.
Research by Harvard University shows that even dim light can interfere with a person's circadian rhythm and melatonin secretion.
We have created an LED downlight that reduces the harmful blue light wavelengths.
- Reduces Blue Light More Than 50%
- Energy Efficient
- Tri Colour (your choice between warm, neutral and cool white)
- True Colour (extremely close to natural sunlight)
- Flicker Free
This graph demonstrates the amount of blue light emitted from a standard LED downlight, as shown by the blue line. Our blue light reduction downlight has significantly less blue light emitted, as shown by the JH LED curve.
Our blue light reduction downlights can protect your eyes and help you have better quality sleep.
As of publishing this, we are the only UL certified LED blue light reduction downlight in Australia.
UL Labs is an independent body that aims to make secure, safe and sustainable living and working environments for everyone. UL focuses strongly on quality, and has been a trusted certifier for over a century, allowing you peace of mind when purchasing a product with their certification.
Where to use blue light bulbs?
We recommend installing our downlights in your bedroom, study and living room, as they’re the rooms you’re most likely to be in prior to sleeping. It’s important to switch out old lighting in these rooms to ensure you’re setting yourself up for the best sleep possible.
How to get natural lighting?
A scale called CRI, or colour rendering index is used to determine how natural looking the light emitted from a lighting product is. It is measured from 1 to 100, with the sun being 100.
Our blue light reduction downlights have a CRI of 97, making them super close to natural sunlight.
Having lights that emit a light close to natural sunlight can make everything look more vibrant, fresh and real.
The example below is a comparison of our blue light reduction downlights, vs a standard downlight.
How to choose blue light globes?
Checklist for choosing blue light lighting:
- If they claim to block 100% of blue light, or cure illnesses, check their claims are backed up by a a certification
- Ensure the verification is from a reliable company (eg. UL Labs)
- Check if the LED blue lightbulbs are dimmable and flicker free
