PH 3/2 Table Lamp, an icon of Danish lighting design

The PH 3/2 table lamp embodies one of Poul Henningsen’s most significant explorations of light. Its three-lampshade design stems from the PH system developed in the 1920s to control electric light and reduce glare. This reissue combines three hand-blown opaline glass elements with a glossy lacquered aluminium base. In its glossy opaline beige and opal white finish, the PH 3/2 retains its historic identity while naturally fitting into contemporary interiors.

The PH System: A Lighting Revolution

As early as 1925, Poul Henningsen developed a system of stacked reflectors designed to diffuse light more softly. He relied in particular on the logarithmic spiral to achieve uniform light distribution and reduce glare as well as annoying shadows. The first lamp using this principle was designed with Louis Poulsen for the 1925 Paris International Exposition, where it received a gold medal.

The PH 3/2 builds on this concept with an upper lampshade measuring approximately 30 cm combined with the two lower elements of the PH 2/2 model. This combination creates an instantly recognizable silhouette that has become one of the hallmarks of Danish lighting design.

Blown glass for visual comfort

The three lampshades are made of hand-blown opaline glass. Composed of three layers, they feature a glossy exterior and a sandblasted interior. This glasswork softens the light and creates an even, warm, and glare-free diffusion.

Each lampshade is handmade, highlighting the artisanal craftsmanship associated with the PH collection. Louis Poulsen also designs this lamp as a high-quality piece intended to be a lasting addition to any interior.

Where should you place the PH 3/2 table lamp?

With a diameter of 28.5 cm and a height of 45.5 cm, the PH 3/2 is particularly well-suited for a desk, console table, end table, or spacious bedside table. Its design primarily directs light downward while maintaining a soft diffusion, making it ideal for comfortable accent lighting.

Is the PH 3/2 suitable as a desk lamp?

Yes, its downward-directed light illuminates a work surface while minimizing glare. However, it favors soft, diffused light rather than a highly concentrated beam. It is therefore particularly well-suited for a desk where visual comfort and decorative ambiance are desired.

Which finish should you choose for the PH 3/2?

The lamp is available with an opaline white lampshade paired with a glossy lacquered base in Beige, Burgundy, Blue, or Green. The Beige finish offers a soft, luminous presence, while the Burgundy, Blue, or Green versions further accentuate the lamp’s graphic and decorative character.

What bulb should you use with the PH 3/2?

The PH 3/2 is designed for an E14 bulb with a maximum wattage of 40 W(bulb not included). The switch is located on the 300 cm Textile cable. The fixture is rated IP20 and belongs to electrical class II.

With its handcrafted Opaline glass, distinctive proportions, and nearly century-old lighting system, the PH 3/2 by Louis Poulsen brings a true piece of design history into your home. It’s a lamp worth choosing as much for the quality of its light as for the timeless elegance of its design.
