How light affects productivity and wellbeing

How light affects productivity and wellbeing

Friday 14 August 2020

Whether you’re reading, working or enjoying a cherished hobby, the light you use has a profound impact on your well-being and the way you see both detail and colour.


When reading, insufficient lighting can result in reduced contrast, causing your eyes to work harder to process the information on the page. This leads to eye strain and all the unpleasant symptoms associated with it. On the other hand, if the light is too bright, it can cause headaches or migraines.

One of the critical components of a great light is adjustable brightness, allowing you to pick the right level of light output for the ambient conditions, helping you to read for longer and in more comfort.


If you enjoy a hobby of which colour is a key component such as artwork, needlework or craftwork, the ability of the light source to show colours accurately should be a consideration. This has a direct impact on the quality of work you produce.

The Colour Rendering Index (CRI) is a scale measured out of 100 that determines how accurately a light source shows colours of illuminated objects in comparison to natural light. A light with a high colour rendering score will make it much easier to distinguish between navy blue and black thread, for example.

If illuminated by lights with lower scores, colours shown will be inaccurate and washed out.

Blue Light

Too much of the wrong kind of light can have a negative effect on your well-being. Blue light, often found in poor artificial light sources such as cheap LEDs and digital screens, can restrict the production of melatonin, a hormone that dictates the circadian rhythm.

Therefore, it is important to either work under natural light or an artificial light source that removes the spike in blue light from the spectrum.

Serious Lights

Serious Lights* use bespoke Daylight Wavelength Technology TM to shed an unsurpassed light beam that mirrors the daylight spectrum as closely as is technically possible. This means you will be able to see every word and image as though you were reading under a pool of pure, natural light.

They do not suffer from the blue light spike common in standard LEDs, allowing you to read in more comfort without the associated negative effects of blue light.
