• Full Spectrum & HCL

We believe that full spectrum is the future

Westal has placed great emphasis on the benefits of full spectrum lighting and currently offers a growing range of fixtures with full spectrum as an option. Our best-seller, the Athena plafond, is now available with full spectrum, as well as our industrial fixture WLF IP44 and Acis bench light. These fixtures are marked with a full spectrum symbol on our website to make them easy to find.

The work towards improved health and gentler lighting continues, and Westal aims to keep developing and be the best in the industry in full spectrum lighting.


 

A light that imitates sunlight

Full Spectrum LED refers to light that more closely mimics daylight and has a CRI (Color Rendering Index) greater than 97. The high color rendering means it is better at reproducing the true colors of objects.

The fact that we tend to feel better on a sunny day compared to a cloudy one can be linked to the idea that full spectrum lighting is more ideal for our health, as there are similar differences between natural daylight and the artificial light we are exposed to daily. Furthermore, full spectrum lighting is also more comfortable and less harmful to our eyes.

To measure the color temperature of full spectrum LED, 15 reference colors are used, and an average is then taken. By performing the measurement in this way, the result is a more balanced color distribution and helps avoid overexposure to blue light, which can damage the eyes.

With full spectrum, a light that closely resembles sunlight is achieved. Here, a comparison between "regular" LED diodes, full spectrum, and sunlight is shown.


 


 

HCL - Human centric lighting

Throughout the day, the light from the sun varies from warm white in the morning (around 2000K) to a cooler temperature at midday (>5700K), before returning to warm white in the afternoon/evening (around 2000K). Human Centric Lighting means using artificial light to replicate the sun's light throughout the day with variable color temperature and light output, typically controlled by DALI type 8 drivers. This leads to increased efficiency and better circadian rhythm.


 

Blue light might harm your eyes

Overexposure to light has the same effect on the eye as it does on the skin; it causes premature aging. The light with the highest energy level is blue light, which, with its short wavelength, contains more energy than other types of light, which have a longer wavelength.

Blue light can lead to various symptoms in people:

• Dry/irritated eyes
• Blurry vision
• Headaches
• Premature aging and deterioration of the eyes

Another harmful effect of excessive blue light can be sleep deprivation, as blue light has the ability to block the body's production of melatonin (the hormone that regulates sleep). Sleep deprivation, in turn, leads to further effects, such as a weakened immune system, poor memory, and weight gain.

Today, people spend more and more time indoors, and as a result, not enough people get the necessary daily dose of sunlight. We need daylight to feel good both mentally and physically.
