The recessed compact luminaire with a diameter of 86 mm can be installed in dry and damp rooms, such as kitchens and bathrooms, thanks to its durable aluminum housing with dust and moisture protection class IP54.
A high color rendering index (CRI>90) means that the shades of objects in the interior are not distorted, and the intense luminous flux and narrow radiation angle - 36 or 60° - allow the lamp to be used when creating directional illumination of interior elements.
The luminaire connects directly to 230 V AC power and is suitable for lighting residential, commercial, public and other spaces.
