Though an average of 500 lux is the norm, it’s crucial to adjust office lighting so that it facilitates the smallest tasks, giving employees maximum personal control and flexibility. While normal light intensity is sufficient to illuminate the task area of a CAD workstation, someone who’s proofreading or doing skilled manual labor, for example, will require 750 lux. For multi-purpose spaces, depending on the needs, type, and size of the installation, Philips designs lighting systems such as SpaceWise, Interact Pro, and Interact Office. Among other functionalities, these systems let users easily adjust lighting levels and settings in their own personal spaces.
It’s also important to consider the surrounding and background areas of the task field you’re working with. A lighting distribution that’s well-balanced between these areas promotes visual comfort and performance.
In addition, consider the ages of the people who use your space. Elderly people, especially those performing tasks that require higher levels of visual performance, could require more than 500 lux – and even up to 1000 lux.
And don’t forget that lighting should also make people look better, highlight objects, and reveal texture – goals that you can achieve using cylindrical illuminance, modelling, and directional lighting.
