Built-in downlights of the BLIZZARD series with a power of 16 W will ideally fit into the interior of a residential apartment, as well as a small cafe or hotel room. The aluminum case smoothly expands towards the base, as if merging with the ceiling surface. The diffuser is located deep inside the body of the lamp, which guarantees the absence of a sharp blinding glow. The high color rendering index (CRI>90) provides an almost natural perception of colors and shades of surrounding objects.
