S-4 Fresnel

Fresnel LED light

The S-4 Fresnel is a lightweight and compact high-power LED light with superb color mixing and very low power consumption; ideal for the broadcast and stage industry where high quality lighting is essential.

The S-4 Fresnel comprises red, green, blue, amber and mint LEDs that mix directly in the light source. Additionally, it has a dichroic enhancer to create a deep blue (Congo blue) that delivers a very saturated blacklight effect. 

This fresnel LED light delivers the most amazing color rendering, and with a CRI > 90 and a TCLI > 90 it is equally impressive in white. The Studio mode offers even higher values: A TLCI of 92.6 in RAW (6.938K) with maximum brightness, a TLCI/CQS/CRI of more than 91 in 5,600K and a CRI of 94.5 in 3,200K. This mode also includes an incandescent dimming curve to emulate tungsten performance. 

Equipped with a Fresnel lens, the optical system is designed to deliver not only a staggering output for a fixture with such a small footprint but also a perfect color mix with a completely even field without any hotspot.

Hue, tint, tone and intensity are fully tunable and can be seamlessly adjusted from 2,000K to 10,000K, as well as between plus/minus green and individual colors. This ensures the uniformity of light and single shadow rendition, while also obtaining a perfect match between the RGBAM colors of the luminaire and the onsite production and environment. All these modes can be adjusted via a manual 4-knob control panel integrated in the base of the luminaire. 

The S-4 Fresnel provides a flicker-free, color consistent 0-100% 16-bit dimming control to achieve the intensity required, with the side benefit of energy and costs savings.  

The integrated fan provides variable fan control through three fan settings for quiet operation: silent, normal and max fan speed. 

The durable, IP65-rated exterior of S-4 Fresnel and the built-in dehumidifier ensure that the fixture is kept free of externally induced impact on internal optics and light source unit, such as smoke fluid, dust and dirt. Thus, the S-4 Fresnel is ideal for outdoor applications and at the same time it is practically maintenance-free making it a sustainable and long-lasting choice for indoor events and installations as well.

With an impressive zoom range from a 10° beam angle to a 76° field angle, the S-4 Fresnel enables gaffers and lighting designers to create everything from very narrow to very wide even fields. Because of its unlimited color options and unique high color rendering capabilities, the S-4 Fresnel is highly suitable for multiple applications such as theaters, film, television and studios or any other application where a bright high-quality output, stunning colors and dramatic color effects are desired.  

Accessories such as barndoors, top hat and an alternative Micro-Fresnel lens option with a zoom range of 4.8°-34° are available, thus expanding the flexibility of the luminaire even further.

The S-4 Fresnel can be mounted standing or hanging with the optional 28mm Spigot and quarter-turn locking for Omega bracket. 


The S-4 Fresnel is a DMX-controlled fixture with RDM protocol implemented for remote configuration, control and monitoring (optional wireless DMX / RDM available on request). Built on a foundation of thoroughly tested technology, the S-4 Fresnel is a robust and highly reliable fixture. 

Via DMX, the user can quickly update firmware through the SGM USB uploader cable, ensuring a long-lasting investment.
