//PATENTED OPTICS
Our internationally patented optical system optimizes the LED source. The reflector design in combination with a Fresnel lens gives us the highest optical efficiency in the industry. De Sisti is able to achieve similar outputs to our competitors with half the power requirements. Our Super LED Fresnels produce the exact  light you’ve come to expect from a traditional Fresnel. 

//GLASS FRESNEL LENS
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.

//SILENT OPERATION, WITH THE RIGHT TEMPERATURE
We 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.

// UNIVERSAL PSU
De Sisti Super LED Fresnel are ready to use around the world
with auto sensing power supplies accepting voltages from 90-250 volts.

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

F14 Tungsten/Daylight

High efficiency Fresnel lens spotlight

Innovative High Power 400W COB (Chip on Board) Led Array.
De Sisti Internationally Patented optical system for Led Fresnel.
Enhanced CRI (Color Rendering Index) higher than 95
for appropriate chromacity performances.

// 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 fans and heat sink to maintain the LED Array’s constant temperature at a maximum of 65°C / 149°F. The hydro dynamic bearing fan operates silently with a very low RPM
// Interchangeable accessories with our conventional range of Tungsten and HMI Fresnels
// All De Sisti Fresnel Series utilize a ne w Universal Voltage and “Power Factor Corrected”
// Power Supply (PF=0.96)

F14 Features

// Continuous light output at any dimming level. Flicker free up to 40,000 fps. We power our LED array via
// DC current rather than PWM technology used by our competitors
// Same characteristics as a traditional Fresnel: single shadows, spot/flood focus range and exceptional barndoor control
// CRI and TLCI greater than 96 with no shift in color temperature when dimming

Available with either Tungsten (3.200°K) or
Daylight (5.600°K) Balanced CCT (Correlated Color Temperature)

The lighting Performances of the Tungsten Balanced CCT from medium to full flood are similar to those of a 4000W tungsten Fresnels

The Daylight Balanced CCT is similar to a 1200W HMI

The Lighting Fixture is DMX Controlled from 0 to 100% with a super smooth Dimming

Available with either Tungsten (3.200°K)
or Daylight (5.600°K) Balanced CCT (Correlated Color Temperature)

The fixture combines the classical SPOT/FLOOD beam control on an equivalent FOCUS RANGE to a conventional lamp fresnel

Also Available in RP Version

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.

//IP23: these lighting fixtures feature Rain Protected construction in order to safely guarantee operation in any location environment, while keeping the outstanding lighting performances and quality that characterize De Sisti LED Fresnels.
