Poul Henningsenâ€™s PH 3/2 Table Lamp (1927) is a member of the PH 3-shade family, a series of light fixtures designed by Henningsen to produce glare-free and economically distributed light. The three glass shades of the PH 3/2 Table Lamp are arranged in a relationship of 3:2:1, drawing their reflections over a logarithmic spiral, which places the light source directly in the spiralâ€™s focal point. Allowing most of the light to reflect outward and downward from the matte undersides, the glass shades enable 12% of the light to penetrate and contribute to the overall room lighting. The result is a soft, evenly distributed glare-free glow. Bulb (not included): 60W/120V/G16.5. Made in Denmark by Louis Poulsen. Chrome Poul Henningsen: PH 3/2 Table Lamp.
