Simple in design, sophisticated in function: CETUS is the perfect ceiling light for anyone who wants to combine a modern living ambience with technical versatility. Its unobtrusive, flat design blends harmoniously into any environment - from the living room to the bedroom. But CETUS can do more than just look good: With the included remote control, you can control the entire lighting experience from the comfort of your sofa. The integrated dimmer, the RGB colour changer and the infinitely adjustable light colour can be individually adjusted. The soft night light mode creates a calming atmosphere in the late hours, while the subtle starlight effect gives the surface that little bit extra. Thanks to the memory function, CETUS remembers your last selected setting - for instant cosy light the next time you switch it on. Made of high-quality white plastic, CETUS is bright, discreet and modern. The surface is smooth and translucent, giving the luminaire a pleasantly even glow. In addition, the luminaires feature modern LED technology, which stands for a high quality of light. LED light sources are characterised by a long service life and low heat generation.

Understanding LED colour temperature and the Kelvin scale
Colour temperature 2000K to 3000K, the light produced is often referred to as a "warm white", "soft white", occasionally called a "candle white". It ranges from orange-ish to yellow-ish white in appearance. This kind of light is attractive, enjoyable, comfortable and relaxing.
Colour temperature 3100K to 4500K, the light produced is often referred to as a "neutral white", "bright white" or "natural white". Light sources within this range will emit a more neutral white light and may even have a slightly blue tint. This kind of light is bright, vibrant and clean appearing.

Colour temperature 4600K and above, the light produced is often referred to as a "cool white", "pure white" or "day white". Light sources in this range will have a blue-ish white tint to them. The higher the number, the more blueish it will appear. This kind of light will appear crisp, invigorating and energetic.
