DE SISTI LED FRESNELS
LIGHTING QUALITY FIRST:
When choosing a FRESNEL you are expecting:
≫ Appropriate and effective Focusing Range from Spot to Flood
≫Single shadows and their consistency within the Flood Field
≫Even and wide Flood with appropriate Barn-door capability
This is exactly what you get with the DE SISTI LED FRESNELS.
The Internationally Patented Optical system specifically developed by DE
SISTI to optimize the use of a LED Engine Technology in combination with a
Fresnel Lens (or a Plano Convex) is providing to the DE SISTI LED FRESNELS
the exact same lighting projection you would expect from a Standard Fresnel.
The following are some images of the PICCOLETTO’s Light beam projections:
