From the feelings to the action! In the last episode we covered how light can influence our mood and emotions, but once seated at a table we must also think about what we hope to achieve.

Each activity, according to its required concentration level, requires different lighting.

Lux and Lumen are two units usually relegated to the world of the experts, but if understood, can help us choose how to best light our own desks.

Both are linked to luminous flux, but they describe it in different ways. Lumen measures the amount of light emitted by a source, while lux represents the amount of light that reaches a surface and how the area is illuminated by the source. Lux is therefore better suited to determine which light is needed in accordance with our activities.

2000 lux

Are you a fan of model-making or miniatures? High illumination is perfect for performance in visually low contrast tasks: reading pencil writing or dealing with very small size details. Such as high detail works, high precision mechanical tasks or super detailed drawing.

1000 lux

For all students or those engaged in activities that require visual tasks of medium contrast or small size:

intensive reading, handwriting, drawing or sewing.

500 lux

This is enough for less visually demanding activities: reading high-contrast content or large characters such as reading for enjoyment, but also office work that does not require specific attention to physical details.

Another aspect to consider is the viewing angle; what is the angle at which brightness is half that of the brightness from dead center.
A wide angle allows a bigger surface area to be illuminated properly. A more even distribution of light from the focal point to the edges of the working area allows the eyes to focus without getting tired by continuously switching between bright and dimly lit areas.

But why all the differences? Isn’t it enough to put 2000 lux on the desk and failing that, just 500 and cope with it?

The level of lighting in our work areas strongly influence our performance, and therefore has to be chosen with care. An over-illuminated environment is likely to make us tired and fatigued more quickly, resulting in headaches and higher levels of stress.
However, it is easier to lose focus and enter a state of torpor and drowsiness working in an under-illuminated environment. In addition, our mood is affected by a lack of light in the long run.

HOKU, with its 1500 lux and a 120° lighting angle, offers the same level of illumination that filters through a window on a sunny day, allowing us to perform different activities without suffering from eye fatigue.

In its RED Limited Ed. version, you can also enjoy the “relax” setting of HOKU which, with only 700 lux, is designed for casual reading and use by the bed or sofa as a simple spot light.
