The round Bopp Grafico 4-light ceiling lamp has a diameter of 46 cm and is 3 cm high. The warm white light of the integrated LEDs is characterised by a very good colour rendering with a very high colour rendering index of Ra 95. This dimmable LED ceiling light is available in the surfaces anodised aluminium and anodised taupe. When dimming the Bopp Grafico ceiling light, the light colour of the LEDs changes to a warmer tone (from 3,000 Kelvin warm white to 2,000 Kelvin extra warm white) thanks to the dim-to-warm technology. The lamp is available in three different versions: dimmable with a phase-cut and phase-angle dimmer, with a Casambi module or with a ZigBee module. With a Casambi module, it is possible to control the ceiling light via smartphone or tablet using the Casambi app via Bluetooth. With a ZigBee module, the lamp can also be regulated via voice control. Both modules allow the lamp to be controlled via app.
