Dimmable PH 5/5 LED pendant light with three-layer metal and opal glass shade The PH 5/5 LED pendant light stands out with its unusual three-layer lampshade. The upper element is made of black aluminium, while the two smaller components are made of white opal glass and are translucent. This creates a beautiful glow around the light, which shines diffusely and glare-free into the room. The hanging light is particularly effective above the living room or dining room table. The brightness of the light can be adjusted using an external dimmer (Mains Dimmable). The Danish designer Poul Henningsen designed the three-shade system back in the 1920s, which over the years became a trademark of the renowned light manufacturer Louis Poulsen. The collaboration resulted in around a thousand models in a wide variety of forms and variations.
