The Knapstein PIA-2 is a rectangular ceiling lamp. It has a length of 41 cm and a width of 18 cm. In total, this lamp is 5.2 cm high. The light is homogeneously and diffusely distributed downwards through matted glass. The ceiling housing is matt nickel-plated. The lamp has a magnetic holder, so no screws are visible in the ceiling housing and the lamp has a flat construction. Two LEDs, each with a colour temperature of 2,700 Kelvin extra warm white, are integrated as light sources. The PIA-2 can be dimmed on site with a phase dimmer. Other rectangular, square or round ceiling lamps are available from the Knapstein PIA series.
