De Sisti | Super LED F4.7 Daylight P.O.

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.

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.

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.

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
• 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
