Invisible transition between the fixture and the ceiling due to absence of visible trim. We used a lens instead of a conventional reflector. The lens focuses the light beam making luminous flux as soft, even and eye-pleasing as possible. Besides, concentrator optics allows to increase brightness and width of light beam while preventing glare effect. Radiator removes heat efficiently because of its construction and high-quality aluminum used in manufacturing. DALI drivers are available for integrating with Smart Home, and Bluetooth drivers for controlling light directly through smartphone.
