One difficulty is that the rear of the stage lies beneath a ceiling beam. That reduces the maximum height for hanging lights to five meters, making surface area lights the only option for lighting the interior. "Normally, a theater would realize the color mix in such a case with four spotlights. But that would have cast colored and ever-changing shadows on the white floor and the tables," explains Wolfgang Eibert, who has been a lighting technician for twenty years. The only solution he could think of was to use an LED spot with color mixing, and so he set out to find a top quality, compact, and yet powerful spotlight to do the job, that ensured a uniformly soft illumination with a broad beam angle with as little shadowing as possible. He chose ARRI's SkyPanel S30 C. "The perfect solution," according to Wolfgang Eibert: "The output and quality in the various shades of white, and also in the rest of the color spectrum, made them the ideal solution." He also cites the spot's color purity as an important argument in favor of the S30 C, because unlike in film, in the theater the color of the spot needs to always stay the same: "And that is precisely what happens with ARRI lights: all the performance values always stay identical."
