A built-in designer lamp with a well-thought-out design and wide functionality will complement the interiors of houses, apartments, offices, shops, showrooms and other premises where high-quality general lighting is required.
The lamp supports several modes that can be switched using the remote control: glow only in the central part (daylight 4000 K), glow of the outer ring (warm 3000 K) or both modes simultaneously.
Recessed optics eliminate the glare effect. High-quality color rendering leaves colors bright and clear. No pulsation of light ensures visual comfort.
