PRODUCT SPOTLIGHT
In 1974, on what would have been Poul Henningsen's 80th birthday, Louis Poulsen introduced a new lamp built on his principles and named for the occasion: the PH 80. It arrived as a floor lamp, and the 80 in the name marks the anniversary.
Starting in 1925, Henningsen brought what Louis Poulsen describes as a scientific approach to lighting, shaping shades along a logarithmic spiral so that light lands evenly across the entire curve, with no hot spot at the centre. Over his career he produced roughly a thousand lamp models on those principles. The PH 80 carried that work forward, built on the system he had refined across four decades of collaboration with Louis Poulsen.
Three Shades and a Red Reflector
The PH 80 runs Henningsen's three-shade system in white opal acrylic. Each shade catches a portion of the light and passes the rest down to the next, so the bulb itself never meets your eye. What reaches the room is warm, diffuse, and indirect, light you can sit beside for an entire evening without glare.
The classic chrome version carries a red reflector under the top shade, a detail held over from the original 1974 design. It goes unseen from most angles, then shows itself from above or from a staircase, adding a warm cast to the light. The monochrome white version trades the red for a white reflector, so the whole lamp, stem to top shade, reads as a single soft object. It suits bedrooms and pale-walled rooms where the lamp should recede into the palette.
The opal acrylic glows evenly across its full surface when lit, holds its colour over years of use, and withstands the knocks that come with living at table height. Henningsen wanted light without glare, and the acrylic delivers it as one continuous, even surface.
The Table Lamp
The PH 80 Table Lamp is a new addition to the family, scaling the design down to console height. It comes in two finishes: white opal acrylic on a high lustre chrome stem, or the all-white version. The shades throw light in every direction, so it behaves as an ambient source. Put it where you want soft ambient light: a console in the living room, a sideboard in the dining room, a deep windowsill.
Our favourite placement is a bedside table in a principal bedroom with a bit of breathing room. The light is warm enough to wind a room down and even enough to read by, and the lamp holds its own as a sculptural object when it is off. On the chrome version, the stem reflects the room around it, candlelight included.
The Portable
Newer still is the PH 80 Portable Lamp, a cordless, dimmable version with a touch control set into the base, introduced alongside the table lamp. It comes in the same two finishes, chrome with the red reflector or monochrome white, and compresses the shade system into a lamp you can carry from the kitchen counter to the dinner table to the shelf beside the tub. Dimmed low, the opal acrylic reads close to candlelight.
A cordless lamp works wherever the seating plan ends up, with no outlet required. This one moves between the centre of a dining table, an open shelf, and the top of a stair landing, and recharges wherever it ends up.
The PH 80 sits inside a larger family we have written about before. The story of the PH 5 pendant covers the three-shade system at dining-table scale, and the PH 1/1 Portable shows the newest chapter of the same system. The PH 80 floor lamp, the 1974 original, stands lamp-height on the same three shades.
Frequently Asked Questions
When was the Louis Poulsen PH 80 designed?
The PH 80 was created in 1974 as a homage to Poul Henningsen on what would have been his 80th birthday. It originally arrived as a floor lamp, built on the glare-free multi-shade principles Henningsen developed with Louis Poulsen from 1925 onward. The table and portable versions are recent additions to the family.
How does the PH 80's three-shade system work?
Three opal acrylic shades sit in a stack shaped so that light distributes evenly across each curve. The shades screen the bulb from every normal viewing angle, so the lamp delivers warm, diffuse, indirect light without glare.
What is the red part inside the chrome PH 80?
That is the top reflector, and on the classic chrome version it is red, a detail carried over from the original 1974 design. The all-white version uses a white reflector instead for a fully monochrome look.
What is the difference between the PH 80 Table Lamp and the PH 80 Portable?
The Table Lamp is a corded lamp sized for consoles, sideboards, and bedside tables. The Portable is cordless and dimmable with a touch control in the base, so it moves freely between rooms and recharges wherever it lands next.
More than fifty years on, the PH 80 still does what Henningsen's lamps were designed to do: put warm, even, glare-free light into the rooms where people actually live. He measured a design by how well it served the person sitting under it, and the PH 80 continues to meet that standard.
