The LED ceiling lamp Bopp Stella Double has two round-shaped, flat lamp heads that are arranged one below the other. The upper light head has a diameter of 45 cm, the lower one has a diameter of 30 cm. The two lamp heads of the lamp are equipped with a total of nine LEDs. These lamp heads each have a thickness of 0.6 cm and emit warm white light to the ceiling, from where it is reflected into the room. The lower lamp head also emits light to the underside of the upper lamp head, from where it is also emitted downwards. The Bopp Stella Double ceiling light has a total height of 30 cm and is available in the surfaces anodised aluminium and anodised black. The ceiling bracket of this LED lamp has the same surface as the lamp head, has a diameter of 12 cm and is 2 cm high. The two elements that connect the ceiling bracket and the two lamp heads are white for the aluminium surface, and black for the black surface. The light of the LEDs is characterised by very good colour rendering with a very high colour rendering index of Ra 95. When dimming the Bopp Stella Double, 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.
