Black Simera LED ceiling light with a large diameter The Simera LED ceiling light with its large diameter and flat shape also illuminates larger rooms with warm white lighting and is particularly suitable for a modern furnishing style thanks to its black lampshade. The light from the LEDs shines very evenly downwards through the matt diffuser, while only a little light penetrates to the sides through the black edge. The Simera LED ceiling light not only provides energy-efficient and bright lighting, it can also be dimmed using any standard wall switch without the need for an existing or retrofitted dimmer. Repeated switching allows the light to be set to three brightness levels: 100 % luminous intensity, 55 % luminous intensity and 20 % luminous intensity.
