Tunable white or dynamic white light is the term used to describe light fixtures that can produce a variable light colour within the spectrum of white light. It can vary from a cool blueish white reminiscent of bright daylight to a warm reddish white reminiscent of incandescent light.

Task lighting is a term used to describe the illumination of a task area within a workplace (e.g. a desk, a counter).

It is used to support a visual task, which expresses the perceptual performance required from the eye to perceive an object. The grade of difficulty of the task increases with the diminishing of colour contrast, size and detail.

There are many standards for workplace lighting that take the visual accuracy and detail of the task into account.

Lighting has so many terms, a lot of characteristics and “shades” to take into account.

Studio De Schutter started creating this Lighting ABC to capture a selection of the terms that describe light.

To describe light is to describe perception with its diversity, complexity and ephemerality. Which is also what we most love about lighting design.
