White plaster LED wall uplighter Tiara with dimmable G9 bulb Tiara has a slightly curved shape and the G9 bulb emits its light exclusively upwards, just as a wall uplighter should. There is no question that this creates a particularly cosy light with a soft, diffuse glow that penetrates the room in a warm and atmospheric way. This can be used to create a cosy atmosphere for many evenings or, for example, to provide a corridor with a pleasant glow of light. If you wish, you can also change the colour of the white plaster surface of the wall light, as the material can be painted.
