The Serien Lighting Drum Ceiling S Long is a ceiling lamp with a mouth blown clear glass. Inside the glass is a conical reflector made of opal acrylic glass. The reflector directs the light downwards and diffuses it softly all around. This lamp is 23.5 cm high and has a maximum diameter of 16 cm. It is available in different versions: with a colour temperature of 2,700 Kelvin extra warm white, 3,000 Kelvin warm white or with Dim to warm function. All versions can be dimmed by the customer. With the Dim to warm function, the colour gradient is reproduced with the warmer light colour of a classic filament lamp. The colour temperature can be continuously adjusted between 1,800 Kelvin extra warm white and 3,000 Kelvin warm white.
