De Sisi use Self Stabilizing Silent Active Cooling technology. The speed of the fan is managed by an internal thermal sensor and CPU, automatically adjusting the temperature of the LED Array to 65°. The hydro dynamic bearing fan operates silently with a very low RPM. A unit must always be silent when it operates, not only with the fans switched off.

You can expect the highest color quality from the De Sisti Super LED Fresnels with CRI & TLCI values above 95 throughout the range. The result ensure maximum compatibility of the light emitted by the devices with optical cameras that have no need for further adjustments,

De Sisti utilizes a true Fresnel lens made of high quality, shock resistant borosilicate glass. Plastics lenses may discolor over time negatively affecting both output and color temperature. Glass is consistent, resilient to heat and offers better uniformity in beam protection.

Continuous Light output at any dimming level. Flicker free up to 40,000
FPS. The LED array is powered via DC current rather than PWM technology
used by others. traditional characteristics as a traditional fresnel ,
single shadow, spot and flood focus range and exceptional barndoor
control. CRI and TLCI greater than 96 with no colour shift in colour
temperature when dimming.

CRI higher than 95 at any CCT throughout the range.Universal A/C input voltage from 90-250V.High quality, shock resistant borosilicate glass Fresnel lens on spring supports. Smooth 100-0% dimming via DMX 512 with no shift in color temperature.
High efficiency self stabilizing silent active cooling: automatic, thermal stabilization of the LED operating temperature is managed by an internal thermal sensor and CPU, variable speed fan and heat sink to
maintain the LED array’s constant temperature at a maximum of 65°C. The hydro dynamic bearing fan operates silently with a very low RPM

From the small 30W 80mm Piccoletto through to the1000W F20 there  is a fresnel to suit all applications.Small studios to large Film studios and location needs. High power versions and Rain proof versions. Pole operated and manual yokes. Retrofit kits are available if you already own older Halogen fittings. A retro fit solution can be fitted within minutes to convert to a new LED engine.

Internationally patented optical system optimizes the LED source. Super LED Fresnels produce the exact light you’ve come to expect from a traditional Fresnel. Years of research have gone into producing the soft edge and constant coverage that comes from a fresenl lens spotlight. The LENS is static and does not move. The Reflector which has exact engineering to match the LED matrix so when the focus is changed the way in which the light interacts with the lens does not change the effect of the fresenl.This allows the interaction between the lens size and what is expected from the light to be predictable.

LED Fresnels are high powered and location ready with IP23 Rain Protection. Three fixtures available: F7, F10 & F14.HIGH POWER & HIGH LUMEN OUTPUT: these new fixtures are ideal to
replace HMIs in outdoor locations as the higher light output is able to
compete with natural daylight without the need of an external ballast.
