For the illumination of the building with floodlights, the aim is to illuminate all sides of the complex as uniformly as possible. An obvious solution is to position the high-performance floodlights symmetrically at the corners of the building. In most cases, one floodlight position is sufficient for two sides of the building. The floodlights are frequently fitted with louvres or shields to ensure that the focus is only on the building. It is recommended that the luminaires should be installed on luminaire poles to protect passers-by from irritating glare. The illumination of the building is supplemented by façade floodlights forming a continuous light strip for linear illumination. As a rule, the final floodlight locations and output levels are only defined after an initial trial illumination.
