The Knapstein SINA-3 ceiling lamp has a length of 69 cm and a width of 20.5 cm. It is 3.8 cm high. Its light is distributed downwards homogeneously and without glare through matted glass. The lamp has a matt nickel-plated surface and, thanks to the magnetic holder, a flat design. Thanks to the magnetic holder, also no screws are visible in the ceiling canopy. The SINA-3 is operated with three integrated LEDs, which can be dimmed on site using a phase dimmer. When dimming, the used Dim-to-warm technology changes the light colour of the integrated LEDs to a warmer tone (from 2,900 Kelvin warm white to 2,200 Kelvin extra warm white). Knapstein also offers smaller or larger SINA ceiling lights.
