The round, dimmable Mabel downlight in white The Mabel spotlight has a calm, cool design thanks to its sand-white housing. Aluminium was used in the design of the downlight, giving it a round shape. The socket for the light sits right in the centre. When the Mabel downlight is switched on, it emits concentrated light towards the floor, creating perfect spotlights. How bright these are can be adjusted using an externally installed dimmer (not included).
