PH 4/3 pendant lamp

Designed by Poul Henningsen and manufactured by Louis Poulsen Denmark.
PH 4/3 Pendel is a member of the PH 3-shade family, and the principle behind the PH 3-shade fixture
was made in a few hectic months in the winter of 1925-26 for a large exhibition hall in Copenhagen,
Denmark called “Forum”.
This is what PH said about his new fixture in 1926: “The real innovation in the PH-fixture is that it
produces lighting which is both glare free and economical. It is easy enough to create
glare-free light (indirect and strongly shaded light) if a portion of the light is allowed to be wasted, and
it is equally easy to make fixtures which are highly efficient if you ignore the fact that they severely irritate
the eye (strong specular reflection, etc.) but it is an art to make light both economical and glare free.”
Before the development of the 3-shade fixture, Poul Henningsen and Louis Poulsen had been working
together on designing the fixtures for the Danish Pavilion at the World Expo in Paris, France in 1925.
When Poul Henningsen designed the fixtures for the World Expo, he had already been playing with the idea
that the logarithmic spiral was perhaps a suitable basis for a new shade structure. The combination of diffused
reflection and a logarithmic shade curve also gave PH the opportunity to control the fixture’s glare and shading,
as each shade would evenly decrease the amount of light emitted according to their distance from the bulb.
The luminance transitions from shade to shade would also appear harmonic. The relative size of the shades
and their positioning was determined by the need to reduce glare - the light disposition on the shades
and the light distribution demands - according to some remarkably simple principles.

The lamp is made from white painted aluminum.
