DeSisti Super F7 Tungsten-Balanced LED Fresnel Light (Manually Operated, Rain Protected)

DeSisti LED F7 Tungsten Overview

Utilizing a powerful, yet efficient 160W LED and a 7" diameter Fresnel lens, the Manually Operated, , Rain Protected Super F7 Tungsten-Balanced LED Fresnel Light from DeSisti can replace a 1000W halogen fixture and provide a versatile spot-to-flood beam angle of 14 to 50° . The specialized tungsten-balanced 3200K chip-on-board LED array offers a high CRI/TLCI of 93 / 90 for accurate color rendition. The unit is also DMX controlled with smooth dimming from 0-100%. It has a high efficiency, Self-Stabilizing Active Cooling system for thermal regulation and a durable, lightweight carbon steel housing to protect the electronics. In addition, it has a built-in universal 90-240 VAC power supply for worldwide use and comes with a 4-way barn door set and a color frame.

7" (175mm) diameter, high quality, shock resistant borosilicate glass Fresnel lens on spring supports. Special patented optics for LED technology.

Rugged and lightweight carbon steel housing with low glare black epoxy powder coating, with internal double walls and reinforcement.

High efficiency, 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 149° F (65° C). The hydrodynamic bearing fan operates silently with a very low RPM.

Steel, cable-driven focus mechanism which guides Teflon bushings supports LED engine along 2 rods. This ensures smooth operation during focusing, in any tilted position of the fixture. The Teflon bushings also provide a wiping action, which cleans the steel guide rails during focus. The focusing mechanism can be activated from both front and rear of the fixture and the entire spot-to-flood action is accomplished with 1.5 turn of the focusing knob.

The unit is equipped with a hinged lens door with a wire-guard and includes accessory holding brackets. One of the 4 brackets has a locking knob and is spring loaded it can be locked to safely hold the barn doors, color frame and scrims. It can also be rotated 90° and locked in an open position for fast accessories changes. A double safety accessory bracket with spring loaded catch is available as an option to be assembled opposite to the locking knob. The accessories are designed for one hand installation and are secure regardless of the orientation of the fixture.
