The lamp belongs to the large PH3-shade-product family, which is based on the idea of reflecting light.
The
PH5 therefore provides a soft light in a way that is easy for the eyes.
The shape of the shade is built on a logarithmical helix, which focal
spot hosts the illuminant. The design of the reflectors ensures that the
light spreads in both vertical and horizontal directions. The lamp is
entirely made of aluminum.
