fos/4 Fresnel
Fresnels have been around since the beginning of lighting design. These incandescent workhorse fixtures are known for their smooth wash, adjustable zoom capabilities, and incredible brightness.
fos/4 takes the most desired features of a standard incandescent Fresnel and adds in the nuanced color mixing, smooth fades, and LED technology of ETC’s other professional grade fixtures. With fos/4, you get a true Fresnel with an LED engine.
It’s time to give your viewers the most realistic environments and skin tones possible. fos/4 is available in both a tunable white light Daylight HDR array and a full color Lustr X8 array.

Intuitive UI
The user interface was designed with the cinematic workflow in mind. Features are simple and intuitive without compromising efficiency. The four backlit encoders change colors to correspond to the attributes they control on the screen.
Even new users can quickly and accurately adjust settings.

Color control
With fos/4 you have the option to change your fixture’s default philosophy. When working with additive color, the fixture often decides how to mix the color requested. There are many different options. Traditionally fixtures choose to mix the
brightest version of the color you’re trying to make. While this gives you intensity, it does not give you quality light. Aiming for quality may mean a noticeable decrease in intensity. We’re now letting you decide what you want to see. Use
the tune functionality to choose brightest or best spectral.
Wireless control
Near field communication (NFC) enables you to push and pull information including fixture setup using ETC’s Set Light app from your mobile phone or tablet, even when the fixture isn’t powered.
Or use City Theatrical’s Multiverse wireless DMX control with your console. Broadcast as many as 10 universes of DMX from a single transmitter without excessive radio energy.

Zoom range
A true Fresnel with LED capabilities, fos/4 Fresnels have zoom control from either the front or the back of the fixture. Adjust the beam then use barn doors or other accessories to control the edges.
Deep Red
With the addition of a deep red LED, we render skin tones, sunsets, and moody saturated scenes better. We’ve reached further into the corners of the CIE color space to grab the deepest red — a red that is essential to accurately capture the warm glow
of firelight, romance at sunset, the most nuanced skin tones, and the truest whites.
