    G-4 Wash & G-4 Wash Beam

    LED Technology

    The G-4 Wash-Beam 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 Micro-Fresnel lens and precise SGM firmware. The LEDs expected lifetime is 50,000 hours.


    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. 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-Beam 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.


    Because of its brilliant optical performance, the G-4 Wash-Beam 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 - 18º zoom range, instead of 4.8º beam angle. By doing this, the G-4 Wash-Beam achieves the best light output for its size, which is also the natural beam angle for this kind of moving head.


    The G-4 Wash-Beam is able to reach 8190 luxes at 5m distance with an excellent white and only 200W. This is one of the many benefits of using RGBAM color mixing, a Wash-Beam front lens, and accurate color calibration. In RAW mode, the G-4 Wash-Beam 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 - 10000K CT control is also provided.

    Micro-Fresnel behavior

    The G-4 Wash-Beam 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 creates sharp defined shadows in flood position, and diffuse silhouettes in spot position with a visible and a clearly defined beam of light.

    Interchangeable lens

    With the addition of an optional interchangeable Fresnel lens, the G-4 Wash-Beam can easily be transformed into a G-4 Wash. The optional Motorized Barndoors lens module with individual DMX control can also be attached to the luminaire. For theatrical purposes, the G-4 Wash and the G-4 Wash Motorized Barndoors act like a regular fresnel light, while the G-4 Wash-Beam lens emulates the performance of a Plano-Convex projector.

    Mounting options

    There are many mounting options available in the G-4 Wash-Beam. 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.

    About SGM


    IP Rating

    All SGM lights are protected by an IP rating of 65 or 66. The durable IP65-rating 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 or gobos 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. The IP-66 rating include the same protection, adding a protection against multi-directional, high-pressure water jets while the IP-65 is protected against low pressure.


    Every SGM light is equipped with an internal built-in dehumidifier protecting the 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.

    SGM’s patented DEHUMIDIFIER, incorporated in the SGM product range, constantly removes trapped hydrogen from inside of the lighting fixture in a solid state electrolytic process with no moving parts. SGM’s DEHUMIDIFIER breaks down corrosive H2SO4 molecules, deriving from polluted air, and eliminates the effects hereof. Hereby, the unique process eliminates any risk of humidity, which would otherwise lead to condensation and corrosion.

    Thermal management

    To achieve optimum performance of the LEDs at all times, SGM lights are optimized to manage heat impact through SGM's unique thermal management technology.

    High power light-emitting diodes (LEDs) use up to 5,000 milliwatts or more in a single LED. However, most of the electricity in an LED turns into heat rather than light. In fact, about 70% becomes heat generation while only 30% becomes light. Therefore, in order to get more light from your LEDs, it is crucial to have efficient thermal management. The SGM technology consists of a uniquely designed body and heat sink, which ensures optimal cooling of the LED chips. All SGM LED products consist 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.


    SGM company

    Originally founded in 1975, SGM brings more than 40 years of experience within the stage lighting business.

    In 2009, SGM decided to bring in industry pioneer Peter Johansen to head the new Research & Development center in Denmark, with the intention to transfer technology, previously only seen possible within stage lighting, into architectural lighting.

    With field expertise dating back to the invention of the smoke machine in the 70s, Peter Johansen, founder of Martin Professional, successfully established the company headquarters in Denmark in 2012, and followed by the introduction of an architectural division offering superior dynamic LED lighting, which comprises colors, strobe effects, pixel lights, positions, patterns, and gobos, in practically maintenance-fee fixtures.
