Large Simera LED ceiling light all in white The flat, round Simera LED ceiling light can be used almost anywhere for ambient lighting in a room, as it is completely white. Thanks to its flat, wide shape, it is barely noticeable on a white ceiling. The LEDs installed in the light provide energy-efficient and pleasant brightness in the room with a warm white light colour. The dimming function via the wall switch offers lighting flexibility. Without the need to install a dimmer, the light of the Simera LED ceiling light can be switched to three brightness levels by pressing the light switch several times, namely 100%, 55% or 20% luminous intensity, so that the brightness of the light can be adjusted to requirements at any time.
