The K2-135 pendant consists of a coloured glass shade, with Tapio Wirkkala’s classic WIR bulb inside. The WIR bulb’s shape and light glow beautifully through the handmade lampshade. The package also includes a dimmable WIR-85 LED bulb, black metal sleeve for ceiling mount, 3.1-metre lead and a ceiling cup. Tapio Wirkkala received an award for the WIR bulb at the Milan Triennial XII in 1960. After this, he created an entire luminaire family around it.
