We often talk about the dangers of blue light in relation to our screen use.
If you’ve been following us for a while you’ll be well aware of the impact blue light from LED screens (like our phones or laptops) can have on your eye health, sleep and general wellbeing.
But what’s less commonly spoken about is LED lighting and the impact of blue light from our everyday light sources – bedside table lamps, reading lamps and general light fixtures.
However, LED lighting often goes unnoticed as it is considered an inevitable part of our homes, our offices, and therefore our lives.
Luckily, we’ve developed a new product to help counter this phenomenon. But more on than in a minute!
The Dangers of LED Lighting
The western world’s movement to LED lighting is a matter of efficiency.
According to John O’Hagan of Public Health England, 95% of what is produced by traditional incandescent lightbulbs is heat, and only 5% is light. If you’ve ever tried removing a light bulb just after switching off your light, you’ll know how that feels!
LEDs also have the added benefit of being thinner, lighter and longer lasting, with stunning colour resolution. It’s hard not to see the appeal.
The International Standard Organisation (ISO) have long recognised the dangers of blue light and had sternly regulated the intensity of LED emissions from our phones until the rise of smartphones.
LED lighting is permitted to be much brighter because you are not expected to stare at it for long periods of time. However, the indirect exposure that we receive from ambient lighting has not been considered or even clinically trialled.
Due to the rigour of modern testing, we would need about 50 years to be able to properly control the participants and variables required to reach a compelling opinion!
How LED Lighting Affects Your Vision
Contrary to what the eye perceives, not all light is the same. We tend to see the light as a uniform white or yellowish colour where in fact all light is actually filled with the many colours of the rainbow.
Depending on your bulb, you may be being exposed to different colours of light in your home. But how do we differentiate between them, and how do they effect us?
There are three main types of light types – incandescent, fluorescent (CFL) and LED.
In the above diagram, we see that cool white LED lighting has a steep and consistent hill of blue light between the 380-450 nm region in comparison to incandescent and CFL lights.
The safest source in terms of blue light exposure is incandescent light, due to its consistency, as some fluorescent lights can still have a spike in blue light around 430 nm. Intrestingly, not all LED lighting can be bad if you have a warm white LED. This reduces most of the blue light exposure.
Introducing the Oculamp
You reduce the amount of blue light emitted from the lamp by cycling through three “temperature” variants.
Cool White [5400k] / Super Bright
For when you want your space at its brightest. This can also help to stimulate your body in the mornings to wake you up
Neutral White [4200k] / Calm White
Kinder on eyes, better for long periods of work. With diffused light and no flickering, this setting will make working more comfortable.
Warm White [3100k] / Night Mode
To help you wind down for the evening. This setting has the least blue light, easing your eyes and improving the release of melatonin into your brain.
The figures you see in K means Kelvins – this is associated with the colour or “temperature” of the light.
