Rounded, weeping trees with dense, low hanging foliage that cannot be seen through, lend themselves to floodlit illumination and the luminaires are best positioned outside the area under the tree. On spreading trees with thin, see-through foliage, illuminating from within the area under the tree, using uplights allows the whole tree crown to appear aglitter. Illuminating a tree with grazing light requires a flat incident beam at approximately 15 degrees. Spherical trees require a greater distance between luminaire and crown than columnar trees do here. Narrow-beamed uplights are particularly suitable for lighting high palms. The desired illuminance must be selected to suit the reflectance of the leaves.
