FRESNELS HIGH POWER // 27
De Sisti LED Fresnels // Lighting quality rst
When choosing a FRESNEL you are expecting:
▪ Appropriate and eective 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 specically developed by DESISTI 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.
DE SISTI LED FRESNELS are 4K Flicker Free operation tested with
Phantom Camera model VEO 640S at 40.000 fps and 2 µs exposure time.
LED Lighting, Green Energy
These LED based products introduce Energy Savings bigger than 92%. LEDs light bulbs last
longer, are more durable - 25 times longer, than incandescent lighting - and oer comparable or
better light quality than other types of lighting. Dimmable LEDs also allow an outstanding
color temperature choices and longevity that extends over decades.
The Beam in full ood is LARGE (above 60°), even
and at (No Hot Spots and rapid passage from
Beam to Field Angle)
The Barndoor on the DE SISTILED FRESNEL has
exactly the same functionality obtained with a
PROPER FRESNEL optics
