Description
Overview
A.39 Refractive Square / Rectangular is the refractive version of A.39 by Carlotta de Bevilacqua. Its optics are a patented technology developed for efficiency in a small format and for the regulation on lighting workspaces.
Construction
A lens serves as the primary optical system for each LED, and a small cell holds both. The ballast is included and louvres are supplied separately.
Specifications
595 x 595 x 33 mm (CD103104IN0, ceiling, Black). 28 W, 3503 lm, 5000K, CRI 90, IP20.
Story
A lens that takes the whole LED flux
The lens captures 100% of what the LED emits and directs it with minimum dispersion, giving an efficiency above 90%.
The cell as a screen
The cell around each LED and lens is only a screen. It stops the LED being seen directly from certain angles and leaves the flux untouched, so the optics alone define the character of the light. Carlotta de Bevilacqua is the designer of the range.
