However, LED lights produce a white light which is different to incandescent and fluorescent lights, because it is produced through a mixture of red, green and blue LEDs.Ī standard LUX meter cannot measure LED light illuminance because it can only measure white light, and LEDs contain more blue light wavelengths and other colours. LED lights are now the most common type because they are energy efficient, have a better longevity and are therefore better value for money, and they are also safer. Most workplaces or commercial environments use one of three types of light source incandescent lights, fluorescent lights or LED lights. However, if you spread the light over a larger surface area the illuminance would not increase exponentially, as we know, the same light over a larger surface actually gets dimmer, so the illuminance would decrease. So if you have a light source which emits 1000 lumens and these are spread over a surface measuring one square metre, you would have an illuminance of 1000 lux. Lux is a unit of measure used to indicate the number of lumens falling either on a square foot (known as foot-candles) or on a square metre (known as lux) of a given surface.

For a light bulb, the wattage is indicating the energy consumption of the light bulb, not its brightness. So when we are looking at the brightness of a light source we are looking for lumens rather than wattage. So a higher lumen output will mean a brighter light with a higher intensity, and a lower lumen output will produce a dimmer light and a lower light intensity. A light bulb, for example, has the amount of lumens it produces indicated on the package. Illuminance is measured in ‘lumens’ which is a unit of measure used to quantify the amount of visible light the human eye can see. To measure light we use a metric called ‘illuminance’, and this gives us the level of light intensity in a given space. This can be for safety reasons, to ensure accuracy or to ensure that energy is not being wasted. With even highlights, you can create a cosy place to work.We measure light intensity in order to understand whether a particular light source provides sufficient light for an intended application. In addition, you can create individual islands of light in the room: An atmospheric illuminated picture on the wall, an LED floor lamp (such as an uplighter) in the corner and a LED table lamp on a shelf are just a few of the creative ideas for harmonious study lighting. Spot lighting in the study is recommended in normal daylight.Alternatively, pendant lights provide the basic brightness needed.

On bright, sunny days, the LED ceiling lighting can stay off altogether. Depending on your requirements, you can turn on all the spots, or just some. Modern LED lighting is ideal: you can spread several spots over the entire ceiling to illuminate the room evenly. Bright basic lighting is essential to get you motivated in the winter and on cloudy days.At the same time, you can always let your eyes stare into the distance – this relaxes the eyes and the mind. Sufficient daylight will then fall on the workspace without dazzling you.

Ideally, your desk should be positioned sideways to a window.

When first creating your home office, you should consider optimal lighting for the workspace with a mix of daylight, direct and indirect lighting:
