The Louis Poulsen Story
Back in 1924, Danish machine and electrical supply company, Louis Poulsen & Co., began working with designer Poul Henningsen to participate in an art exhibition in Paris. The result, the Paris lamp, used three rounded shades layered on top of each other to produce glare-free light. It won a gold medal, an achievement that led to a contract to provide lighting for the new Forum building in Copenhagen.
From that point on, the Louis Poulsen specialty was the design and production of modern lighting. Today, with its precise and functionally innovative layers and crisp white tones, Louis Poulsen lighting is recognized and specified the world over.
Why We Love Louis Poulsen Lighting
When you hear the name Louis Poulsen, you think distinctive modern Danish lighting. From the classic icons of the 1920s to more recent pieces, all Louis Poulsen lighting is created based on a deep-felt respect for architecture, understanding the emotional effect of lighting and the belief that shadow is just as aesthetically important as light. All three aspects manifest themselves in the sculptural layering and comfortable, glare-free light of Louis Poulsen pendants, wall, table and floor lamps. Over the years, the Louis Poulsen design philosophy and signature look have attracted the talents of such notable designers as Poul Henningsen, Arne Jacobsen, Verner Panton and Louise Campbell.
A Fun Fact About Louis Poulsen
The story of Louis Poulsen doesn't begin with lighting, or even with electricity. It begins with wine. In 1874, Ludvig R. Poulsen established a wine importing business in Copenhagen. It was based on the success of this company that he was able to open a second business selling tools and electrical supplies. His nephew, Louis Poulsen, eventually took things over in 1906.
Noteworthy Lighting From Louis Poulsen
Originally designed in 1958 by Poul Henningsen, the Artichoke Pendant has since become the most recognizable piece in the Louis Poulsen collection. It replicates the form of the eponymous vegetable with 72 precisely placed leaves. In addition to creating a generally fascinating structure, these leaves effectively provide glare-free light from all angles. The entire PH collection by Henningsen established the Louis Poulsen aesthetic. It is based on the three-shade system that Henningsen developed in 1925-1926, with symmetrical, curved metal discs that direct the majority of light downward.
Key Features
The Louis Poulsen PH 4 1/2 - 4 Glass Pendant Light is part of a lighting family that can truly be called timeless. Designed by Poul Henningsen in the mid 1920's using the logarithmic spiral as a template (science!), the eventual move from metal to glass shades resulting in an evenness and expansiveness of the light distribution. The numbering series references shade size combinations (4.5=45cm, and so forth), with the descending configurations affording the opportunity to hang at lower heights.

Compare Brightness:
Lumens

HalogenLumens
The amount of light that comes from a bulb, which has commonly been measured in watts. The more lumens, the brighter the bulb.Wattage
A measurement of the power delivered to a component of an electric circuit (allowing a one-ampere current to flow through the component under the pressure of 1 volt.)Bulb Shape
Bulb shapes are denoted with a letter, which describes the shape, and a number, which indicates the size. The number indicates the diameter of the light bulb at its widest part in eighths of an inch.Base
The part of the bulb that connects to the fixture and its power supply. Bulb bases are denoted with the letter E, and a number which indicates the diameter of the bulb base at its widest part in millimeters.Voltage
Indicates how much voltage a bulb can accept via the fixture it's installed in.Light Color Temperature
The relative color from a light source, measured on the Kelvin temperature scale. Warm light is lower in color temperature (2700-3000 K) and cool, blue light is higher (5000 K).Average Rated Life
The average amount time that a bulb is expected to last.CRI
CRI = color rendering index. This number, which can go from 0 to 100, measures the ability of a light or bulb accurately renders colors. The higher the number, the better, with most quality bulbs these days measuring at least in the 80s.Manufacturer IDs: view
