The PH 3/3 Pendant Centenary Edition marks 100 years of System PH, the three-shade principle Poul Henningsen worked out in 1926 and then applied to hundreds of lamps. The proportions are the familiar 3:2:1 with a top shade of about 30 cm, which makes this a whole size PH, drawn to stay glare-free when it hangs higher in a room. The upper shade is four-layered mouth-blown amber glass with a white inner side; the middle and lower shades are three-layered mouth-blown white opal glass, glossy outside and sandblasted matt inside, with a frosted diffuser below.
The amber glass sends a warm ambient light upward into the room while the opal shades keep the downward light soft and free of glare. Canopy, suspension and shade fittings are aged, lacquered brushed brass, with decorative thumbscrews that let you adjust the position of the light source inside the lamp. It measures 285 x 307 x 285 mm, weighs 5.5 kg and hangs on 4 m of dark brown textile cord.
Light source: E27 socket, 1 bulb, max 13 W LED, IP20 indoor, not dimmable. Bulb not included.

Louis Poulsen
The PH system in its pure 3:2:1 form since 1926
DesignerPoul Henningsen1894–1967
The PH 3/3 shows Poul Henningsen's three-shade system in its original proportions. A top shade of about 30 cm sits over middle and lower shades in a 3:2:1 ratio. As a whole size it stays glare-free when hung higher in a room, in metal, opal glass or a mix of both.

Glare-free from below
A whole size, it is calculated so the bulb stays hidden even when the lamp hangs high.
Compact at 28.5 cm
At 28.5 cm across it fits small tables, stairwells, hallways and bedrooms.
Three material mixes
Choose black metal, white opal glass, or black metal with opal glass.
Warmer special editions
Pale rose, aged brass and the amber Centenary Edition bring warmer tones.

The 3:2:1 rule
Each shade sits on a logarithmic spiral with the bulb at its focus. The top, middle and lower shades follow a 3:2:1 ratio, so light is caught and redirected before it reaches the room.

Whole size or hybrid
In Henningsen's naming, two equal numbers mean a whole size. The PH 3/3 is made to stay glare-free when hung higher, unlike hybrids such as the PH 3/2 that hang low over a table. That makes it a good fit for stairwells and halls.

Metal and glass
Metal shades send all the light down and out, with soft-touch black outside. Opal glass shades glow as well as reflect. The mixed version pairs a metal top with glass below, so you get a little of both effects.
Materials
- Painted aluminium
- Soft-touch black outside and white inside for even, glare-free reflection.
- Mouth-blown opal glass
- Three layers, glossy outside and sandblasted inside; wipe with a damp cloth.
- Brass on editions
- Untreated brass darkens with time; aged brass is lacquered to keep its finish.
Henningsen was a Danish architect, writer and designer who began working with Louis Poulsen in 1924, a partnership that lasted until his death in 1967. His lamp for the 1925 Paris Exposition won gold, and in 1925–26 he set out the three-shade system behind the whole PH collection.
Using it at home
Which bulb should I use?
One E27 bulb. A warm LED of about 2700 K suits the glass and brass versions.
How high should I hang it?
It works hung higher in a room, in a stairwell or hallway, and also over a small table.
PH 3/3 or PH 3/2?
The PH 3/3 is a whole size for higher hanging. The PH 3/2 is a hybrid made to hang low over a table.
Can I dim it?
Yes, with a dimmable bulb and a compatible dimmer.
How do I clean it?
Let it cool. Dust metal shades with a dry cloth and wipe glass with a lightly damp cloth.
