Over a decade of research has been realized in the fos/4 Panels. It’s time to give your viewers the most realistic environments and skin tones possible. Why fix in postproduction what you can realize in production? fos/4 is available in both a white light Daylight HDR array and a full color Lustr X8 array.


The eight-color mix pushes the boundaries of color rendering possibilities. Reaching further into the visual spectrum, you’ll be amazed at what your camera reveals with fos/4.


With two arrays each available in small, medium or large, you pick your lumen output. With up to 62,000 lumens, brightness comes without compromise.


All fos/4 Panels are backed by ETC’s 24/7/365 support and standard fixture warranty – 5 years on the full fixture and 10 years on the array.

Lustr X8 Array with Deep Red

With eight colors of LEDs, 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, and the most nuanced skin tones.

Compared to other leading panel lights, fos/4 is brighter at nearly all color points.
