The G-4 Wash-Beam POI is a fast and compact wash moving light capable of outstanding color rendering and a sharply defined beam angle. The optical system is designed to deliver a high-quality color mix with an accurate and precise beam of light. Because of its remarkable output, wide zoom range, qualified color reproduction, accurate color temperature control, and low power consumption, the G-4 Wash-Beam POI is a very flexible projection luminaire suitable for any application.
Construction
The G-4 Wash-Beam POI with full 'moving head' functionalities is designed and manufactured in Denmark and blends in with any contemporary or historical architecture. Base and heat sinks are made from extruded or pressure cast marine grade aluminum, Oxsilan ® pre-treated, and powder coated to corrosion class C5-M marine grade. The yoke and fan covers are made of durable materials, including impact and UV resistant P6.
LED Technology
The G-4 Wash-Beam POI is the first projector able to achieve a coherent and qualified light spectrum in all color temperatures by only using five colored LEDs. This is possible because of the combination between RGBAM additive mixing, included Micro-Fresnel lens, and precise SGM firmware. The G-4 Wash-Beam POI is able to reach 8190 lux at 5m distance with an excellent white and only 200W. Linear 2000K - 10000K CT control is provided, and in RAW mode the G-4 Wash-Beam POI outputs a color temperature close to 7,000K with CRI, TLCI, and CQS values above 90. These values are in a similar range when using 5,600K or 3,200K in calibrated RGB mixing. The LEDs expected lifetime is 50,000 hours.
Colors
This small but powerful fixture includes RGB mixing in its lightsource with additional amber and mint LEDs to fill the typical gaps of a LED spectrum offering rich whites in all different color temperatures.Thanks to the LED cube principal, any shade of color or white is immediately perfectly mixed, leaving no trace of color shift even at a very short distance. 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-Beam POI delivers unique features. Its zoom range goes from 4.8° to 34°º with smooth transition and no color shifts. The optical system is designed so maximum output is achieved in the 15º to 18º zoom range. By doing this, the G-4 Wash-Beam POI achieves the best light output for its size.
Micro-Fresnel behavior
The G-4 Wash-Beam POI uses a Micro-Fresnel front lens capable of a bright light output while delivering a similar performance of the traditional Plano-Convex lenses. As a PC-like luminaire, the G-4 Wash-Beam POI creates sharp defined shadows in flood position, and diffuse silhouettes in spot position with a visible and a clearly defined beam of light.
Full control via Studio Mode
The G-4 Wash-Beam POI 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.
Durability
The durable IP66-rating of the G-4 Wash-Beam POI luminaire ensures that the fixture is kept free of externally induced particles and liquids on internal electronics, optics, and light sources, including acidic air pollution, making it ideally suited for near- and offshore areas with high salinity. The need to clean optics is eliminated and no internal corrosion will occur. Extensive testing ensures maximum durability to vibration and physical impact. Learn more about SGM's testing
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. POI products installed on permanent installations must always be powered on, so dehumidifiers perform properly. Learn more about dehumidification
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-Beam POI 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
The G-4 Wash-Beam POI can be mounted in any direction. Additionally, M-10 bolts are included, which ensures the fixture can be tightly screwed to a surface, protecting it from both vandalism and theft. The M-10 bolts are suitable for any kind of custom-made bracket and are included with all POI fixtures. An omega bracket made of untreated marine grade stainless steel, perfect for permanent rigging, is available as an accessory.
Included SGM technologies
ThermalDriveTM
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 ThermalDriveTM 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.
TruColorTM
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.
DryTechTM
SGM's integrated patented Dehumidification process eliminates humidity and breaks down corrosive 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 DryTechTM 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.
