Siona LED table lamp with a practical flexible arm – including dimmable and CCT function The Siona LED table lamp combines both elegance and functionality in its black design. The integrated controllable light colour (CCT) makes it possible to adjust the light colour as required – from warm tones for a cosy atmosphere to cooler shades that promote concentration. Ideal for the living room or study, Siona's integrated LED light source provides an energy-saving light that simultaneously increases productivity and invites relaxation. In addition, Siona is dimmable in three stages. Both functions are controlled by a built-in switch. The LED table lamp Siona has a contactless charging station that can be used to charge other devices. Furthermore, it is delivered without a power supply unit and can be operated with the proven 5V or 9V - to enable faster charging.
