Wästberg's Pastille clamp lamp, designed by Sam Hecht and Kim Colin, consists of a disc-shaped shade and a slender stand with a touch dimmer hidden at the top. The material of the luminaire resembles painted metal in appearance, but is actually biopolyamide; the plant-based, recyclable bioplastic is made from castor oil.

Thanks to the combination of an advanced COB LED light source, a large reflector and a concave diffuser, Pastille emits a pleasantly soft light with a warm white color temperature of 2700 K. Despite its extremely simplistic, geometric design, Pastille is a very versatile luminaire: its shade rotates smoothly around its axis, so the light can be directed to the pages of a book, for example, or turned facing the wall to create atmospheric general lighting.
