The PH 1/1 Portable Lamp is the most compact expression of System PH — the smallest “whole” shade set, with a roughly 10 cm top shade in Poul Henningsen's golden 3:2:1 proportion — translated into a rechargeable lamp a century after his 1925 Paris gold medal. The mouth-blown white opal glass shades layer the light downwards without glare, on a machined brass base in high-lustre chrome or brass metallised finish.
Free of cords and sockets, it glows on a bookshelf, windowsill or bedside ledge, joins the dinner table, then moves to the balcony for a warm evening outside — its diminutive scale never crowds a surface, and the layered shades read unmistakably as Danish design even switched off. Pair it with larger PH family members from our Louis Poulsen collection or compare our portable lamps.

Louis Poulsen
The smallest shade set of the 1926 System PH
The PH 1/1 is the smallest shade set in Poul Henningsen's System PH of 1926, with a top shade of about 10 cm in his 3:2:1 proportions. Louis Poulsen builds it as a chandelier, a cordless portable lamp and a piano table lamp, all with mouth-blown glass shades.

Glare-free up close
PH's whole-sized lamps are designed to be especially glare-free, so the small shades stay comfortable near your eyes.
Mouth-blown glass
Every shade set is mouth-blown opal glass with a sandblasted inner side for soft, diffused light.
Three ways to use it
Hang it as a chandelier, carry it as a cordless lamp, or aim it over a desk or piano.
Heritage editions
The Chandelier Centenary Edition and the Piano Table Lamp Limited Edition 2026 revive designs from the 1930s.
The system behind it
Henningsen based System PH on the logarithmic spiral. Each shade reflects the light onto the next, so it leaves the lamp soft and glare-free. The system has spanned hundreds of models, and the PH 1/1 is its smallest whole set.
Chandelier and piano lamp
The chandelier, first known as the Bombardement Chandelier, was in the catalogue from 1933 until the mid-1960s and returns with 3, 6 or 9 arms. The Piano Lamp of the early 1930s carries a PH 1/1 set on a curved, counterweighted stem.
A cordless PH
The PH 1/1 Portable puts the shade set on a brass metallised or high-lustre chrome body. Its dim-to-warm LED moves from 2700 K down to 1800 K, and it is rated IP44 for indoor and outdoor use.
Materials
Mouth-blown opal glass
Three-layered opal on the Portable and four-layered dusty terracotta on the Centenary and Piano editions, all sandblasted inside.
Aged brass
Brushed with fine hairlines and lacquered on the chandelier and piano lamp; dust with a dry cloth.
Metallised or chrome-plated aluminium
Top plate, body and base of the Portable.
Designer and brand
Poul Henningsen
1894–1967
Henningsen studied at the Technical School in Frederiksberg and the Technical College in Copenhagen but never graduated as an architect. In the 1920s he met Louis Poulsen's director Sophus Kaastrup-Olsen, the start of a lifelong collaboration. He developed the three-shade system in 1926.
Using it at home
How long does the Portable run?
About 5 hours at 100%. It charges by USB-C with a standard 15 W/3 A adapter, with stepless and 4-step dimming.
How do I clean the glass?
Let the lamp cool, then wipe the shades with a soft, damp cloth and dry them.
Can I use it outdoors?
Yes. It is rated IP44 for indoor and outdoor use.
What light does it give?
A 2.5 W dim-to-warm LED that moves from 2700 K down to 1800 K as you dim.
How big is it?
It is 291 mm tall with a 160 mm shade, and weighs 1.8 kg.
