04 DESISTI

The DE SISTI LED FRESNELS Tungsten are:
≫ much less expensive then equivalent HMIs fixtures. They are 100% Dimmable locally or via DMX with super smooth
dimming dynamics
≫All self contained in the Luminaire housing (no separate ballasts or power supply)
≫Power and DMX Daysy chain able
≫Yet introduce significant energy savings when compared to HMIs
≫Extremely contained Maintenance (mostly cleaning): no expensive lamps replacement

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:
