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 of more than 90 (typically 93) and a TCLI of typically 90 it is equally impressive in white.

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% 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 of 9°-76°, 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, wireless control and monitoring. 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.
