A checklist prepared by the Illuminating Engineering Society (IES) of Finland for measures to be taken if luminaires fail to switch on or to function appropriately in a system equipped with a ballast.
Energy-efficient lighting depends on many factors; do not stare only the efficacy. Energy-efficient lighting is made of high-quality products, good design and execution together with
proper maintenance and energy efficient use of the lighting over its life-time.
Concepts, such as illuminance, glare, and modelling, that are covered by the standard SFS-EN 12464-1:2011 (here you can find information on how to take these concepts into account in the design of lighting, and this section also provides examples of lighting requirements for specific spaces, areas, tasks, and activities).
