Matt white GU10 downlight Jolina with adjustable insert The GU10 downlight Jolina is made of aluminium with a matt white finish. With this colour scheme, there are hardly any limits to the use of the angular downlight, especially as the shape also appears very timeless and simple. The swivelling insert should be mentioned as a special feature of Jolina, as this ensures more individuality when directing the light. The GU10 downlight can be used in many places and is ideal for kitchens, corridors and study rooms, for example - with high-quality, screwless quick-connect clamp (durable, secure and tool-free spring mechanism)
