Recessed downlights of the MIST series have a degree of dust and moisture protection IP54, which allows them to be used in rooms with high levels of humidity and dust: for example, on staircases, in bathrooms, in kitchens and in locker rooms of fitness centers. The wide beam angle of 110° is great for creating key lighting.
The matte recessed diffuser ensures uniform illumination without glare. The white outer frame looks harmonious in interiors of a variety of styles.
