G-4 Wash

LED Technology
The G-4 Wash 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, the accurate lenses, and precise SGM firmware. The LEDs expected lifetime is 50,000 hours.

Colors
This small but powerful fixture includes RGB mixing in its light source 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.

Optics
Because of its brilliant optical performance, the G-4 Wash is one of the most flexible moving heads in the market. It delivers a wide 9° to 76°º zoom range, with all colors accurately mixed before the front lens, and no color shifts, relevant green spikes, or dramatic 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 delivers the best light output for the size of its lens, which is also the natural beam angle for this kind of moving head.

Fresnel behavior
The G-4 Wash is a true fresnel-based luminaire, and it delivers the same performance a user can expect from such a projector. Unlike other LED fresnel lights, the G-4 Wash uses 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 creates sharp defined shadows in flood position, and diffuse silhouettes in spot position.

Top Hat and Motorized Barndoors
To avoid any spill around the lens, an optional magnetic Top Hat is available for the G-4 Wash. However, the G-4 Wash can also be ordered with the optional Motorized Barndoors lens module. This is a powerful and accurate accessory operated remotely via DMX; thus, the manual manipulation of barndoors or focusing is no longer needed. Since Motorized Barndoors creates an external light shape after the lens, a defined light cut can be expected, with the traditional soft graduation.

Full control via Studio Mode

The G-4 Wash includes the powerful SGM DMX Studio Mode, expanding its capabilities through a number of advanced features. Select different dimming curves, choose your preferred RGB CTC, RGBAM, CMY, HSI or XY color mode, adjust fan speed to reduce noise, change the LED frequency rate, and increase or reduce the peaks of green in the white output. Learn more about the SGM Studio Mode by reviewing the DMX chart in the "Download" section.

IP rating
The durable IP65-rating of the G-4 Wash luminaire ensures that the fixture is kept free of externally induced particles and liquids on internal optics and light sources, such as smoke fluid, dust, dirt, airborne pollution, and humidity. Thereby, the need to clean optics is eliminated and no internal corrosion will occur. It is ideal for outdoor applications, while being practically maintenance-free making it a sustainable and long-lasting choice for indoor events and installations as well.

Dehumidification
The internal built-in dehumidifier protects this fixture from moisture, pollution and any other factors that can generate corrosion. The patented SGM dehumidification not only removes humidity but also prevents oxidation and condensation, while a gore-tex membrane equalizes internal pressure to prevent leaks.

Photometrics
The G-4 Wash 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 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. Linear 2000K - 10000KK CT control is also provided.

Interchangeable lens
By the addition of an optional interchangeable Micro-Fresnel lens, the G-4 Wash can easily be transformed into a G-4 Wash-Beam. While the G-4 Wash delivers all the quality and control of a fresnel-based luminaire in a wide zoom range, the G-4 Wash-Beam offers a higher output and a sharper beam of light, to make it clearly visible while using smoke or haze machines. For theatrical purposes, the G-4 Wash lens acts like a regular fresnel, while the G-4 Wash-Beam lens emulates the performance of a Plano-Convex projector.

Thermal management
Thermal management
To achieve optimum performance of the LEDs at all times, this bright and accurate luminaire is optimized to manage heat impact through SGM's unique thermal management technology. The technology consists of a uniquely designed body and heat sink, which ensures optimal cooling of the LED chips. Additionally, the special aluminum alloy and surface treatment ensures maximum heat dispersion while the fan-assisted cooling ensures optimal performance at any time and under any conditions (such as variable temperatures, limited airflows, confined installation spaces, etc.).
Like all SGM LED products, the G-4 Wash consists of SGM's superior thermal management technology and tested under extreme hot and cold conditions, which ensures that the LEDs always operate within safe parameters. Learn more about SGM thermal management

Mounting options
There are many mounting options available in the G-4 Wash. It can be rigged by using the included easy-fit omega bracket with ¼ turn fasteners, it can be installed in any kind of floor thanks to its integrated rubber feet, or it can be mounted with a special ceiling mount to eliminate the need of the base. There are also accessories available like magnetic Top Hats and different front lenses.

Included SGM technologies

ThermalDrive^TM
This thermal management techonology provides Advaced Temperature Control monitored via sensors and software, keeping optimal LED junction temperatures, and ensuring maximum reliability for long-term use. SGM's predictive color mixing algorithm compesates the decay levels of color-based LEDs for superior color rendering. Finally, the ThermalDrive^TM system includes cutting-edge heat removal via passive thermal tecniques and active forced-air cooling (depending on the product), specifically designed to maintain LED efficiency while extending fixture's lifetime.

TruColor^TM
SGM uses Full Range Calibration in all LED fixtures over CIE space and black body curve, measured via spectrometer and SGM Illumination Lab software. The consistency of each product and its lifetime expectancy is monitored throught inbuilt sensors to compensate color shifting and to allow color temperature re-calibration. To provide the best user experience, SGM's Color Match procedure ensures accurate wavelength reproduction within the product range via colored LEDs, dichroic filters, or CMY mixing (depending on the product); all of them specified to match the SGM color palette.

DryTech^TM
SGM's integrated patented Dehumidification process eliminates humidity and breaks down corrosive H₂SO₄ molecules deriving from polluted air to avoid destructive corrosion. Inbuilt dehumidifiers constantly remove trapped hydrogen from inside of the lighting fixture in a solid estate electrolytic process with no moving parts. The DryTech^TM procedure is also based on a Ingress Protection rating of 65 or 66 (depending on the fixture), intended as a full protection against dust and other particles, while ensuring protection against direct water jets.
