G-4 Wash Motorized Barndoors

Introduction of the G-4 Wash Motorized Barndoors

LED Technology

The G-4 Wash Motorized Barndoors is the first moving head able to achieve a coherent and qualified light spectrum in all color temperatures by only using 5 colored LEDs. This is possible because of the combination between RGBAM additive mixing, included Fresnel lens, and precise SGM firmware. The LEDs expected lifetime is 50,000 hours.

Colors

This small but powerful fixture includes RGB mixing in its lightsource but also amber and mint LEDs to fill the typical gaps of a LED spectrum and get rich whites in all different color temperatures. Through the Color Emulation DMX channel, it is possible to match most of the colors present in the LEE catalog and to output only the amber or the mint LEDs. A plus/minus green function is also included for accurate color control in TV and film shootings.

Congo Blue feature

The G-4 Wash Motorized Barndoors solves one of the biggest demands in LED luminaires: a real congo blue color. This moving head uses a physical enhancer to create a deep and saturated blue with the characteristic shade of a real congo blue.

Optics

Because of its brilliant optical performance and efficient manipulation of beam angles, the G-4 Wash Motorized Barndoors makes a real difference in the market. It delivers a wide 9° to 76° zoom range, with all colors accurately mixed before the front lens and no color shifts or color aberrations. The optical system is designed so maximum output is achieved in the 15º - 18º zoom range, instead of 9º beam angle. By doing this, the G-4 Wash Motorized Barndoors delivers the best light output for the size of its lens.

Photometrics

The G-4 Wash Motorized Barndoors is able to reach 7265 lumen with an excellent white by only using 200w. This is the benefit of using RGBAM color mixing and an accurate color calibration. In RAW mode, the G-4 Wash Motorized Barndoors outputs a color temperature close to 7,000K with a CRI, TLCI, and CQS above 90, but these numbers are also in a similar range while using 5,600K or 3,200K in calibrated RGB mixing.

Fresnel and barndoor behavior

The G-4 Wash Motorized Barndoors is a true fresnel-based luminaire with external barndoors and it delivers the same performance a user can expect for such a projector, but avoiding the need of manual focusing. Unlike other LED fresnel lights, the G-4 Wash Motorized Barndoors use a glass fresnel front lens and the size of the luminaire does not change while using the zoom feature. Like the traditional hand-made fresnel projectors, the G-4 Wash Motorized Barndoors creates sharp defined shadows in flood position and diffuse silhouettes in spot position.

Motorized Barndoors performance

The motorized barndoors is a powerful and accurate feature operated remotely via DMX. Each blade has individual -90º to +40º angle control and the whole module rotates from -110º to +110º. The barndoors maintain their position at any time and the automatized control avoids the blades to be damaged. Since Motorized Barndoors creates an external light shape after the lens, a defined light cut can be expected, with the traditional soft graduation.

Interchangeable lens

With the addition of an optional interchangeable Micro-Fresnel lens, the G-4 Wash Motorized Barndoors can easily be transformed into a G-4 Wash Beam. If needed, a G-4 Wash fresnel lens can also be provided to avoid the use of external barndoors. For theatrical purposes, the G-4 Wash Motorized Barndoors acts like a regular fresnel, while the G-4 Wash-Beam lens emulates the performance of a Plano-Convex projector.
