Dim to warm: the dimmable Grand Groove LED ceiling light with smoky grey crystal glass lampshade, Made in Germany The Grand Groove LED ceiling light with its two-part lampshade creates an atmospheric lighting mood. The outer part is made of smoke-grey tinted and corrugated crystal glass, giving the light source its special look. The inner lampshade made of opal white glass emits slightly diffuse light to the sides, while the light is emitted directly downwards. High-quality LEDs with good colour rendering are integrated and emit a warm white light. The light intensity is also externally dimmable via a triac. As the intensity decreases, the colour temperature becomes warmer (dimmable to warm), creating an even more pleasant atmosphere. Grand Groove is visually rounded off by a cylindrical canopy made of aluminium with a black finish. It is handcrafted and produced by the manufacturer BANKAMP in Germany.
