22 // FRESNELS VARI-WHITE
The Super LED Vari-White range maintains the high eciency De Sisti Internationally Patented optical
system for LED Fresnel. The innovative variable white Fresnel provides the ability to modulate the color
temperature from a minimum of 2800°K to a Maximum of 6600°K. The light output has an enhanced CRI
(Color Rendering Index) greater than 94 and with equal output throughout the color temperature range.
THE LIGHTING FIXTURE IS DMX CONTROLLED FOR:
▪ 0 to 100% with a super smooth Dimming
▪ STEP MODE for CCT Control: Increments of 400°K every 10% of DMX variation
▪ CONTINOUS MODE for CCT control.
The xture combines the classical SPOT/FLOOD beam control on an equivalent focus range to a conventional
tungsten lamp Fresnel, with an excellent barn door cutting.
The Fresnel range utilizes standard accessories from the De Sisti range of equivalent Fresnel Lens size, such
as Barndoor, Color Frame, Cones, and Scrims.
LED FRESNEL VARI-WHITE
NEW GENERATION WITH ADJUSTABLE CORRELATED COLOR TEMPERATURE
MAIN FEATURES
// CRI Greater than 94 at any CCT within the range from 2,800°K to 6,600°K
// Universal A/C input voltage from 90-250V and True smooth 100-0%
Dimming via DMX 512
// 120 mm. (4.75”) diameter high quality, shock resistant Borosilicate glass Fresnel lens on
spring supports.
// Silent dimming with no color shift
// High eciency Self Stabilizing 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.
// Helix Screw driven focus mechanism which guides Teon bushings supported LED ENGINE
along 2 rods. This ensures smooth operation during focusing, in any tilting position of the
xture.
// Available with either positive lock manual yokes for comfort and ease of handling, or pole
operated yokes which can be used via the lighting pole for Panning and Tilting the lights as
well as manually, since the mechanical activators are equipped with clutches.
// Modular design construction for maintenance and future upgrades.
