Clusters of trees
Floodlights located in front illuminate the tree crowns evenly. Floodlights positioned at the sides produce a hard contrast of light and shadow. Luminaires on two sides avoid hard shadows. Uplights at the trunk emphasise the trunk as a vertical linear feature.
Having several luminaires with high cut-off angles reduces the glare compared to a few broad-beamed luminaires. Narrow-beamed and well-aimed luminaires reduce the superfluous emission of light into the surroundings. The decentralised illumination of trees allows a differentiated lighting of a cluster of trees. Spotlights are suitable for additional highlights. Tree growth and the avoidance of glare are to be considered when positioning and aiming the luminaires.
