With the help of Peter Wikström, project manager at One Two Sales in Gothenburg, the technicians realized that not only would ETC’s Selador Vivid-R LED fixtures provide the quality and power of light they needed while saving a energy, the theater would also gain some 15 feet of stage depth.
Previously, a large gap had to be kept between the luminaires and the cyc wall itself. The Selador fixture, which can be mounted on the last flying bar, allows a greater area of stage to be used.
The Vivid-R fixture combines Luxeon Rebel LEDs and efficient lenses for a strong beam of light and the Selador x7 Color System, which creates a wide array of vibrant colors.
“I was looking for a light that could combine the old traditional halogen cyc with the possibilities of modern LEDs,” said Anders Johanssen, lighting manager at the theater. “It was important to be able to do long smooth fades and quick strobe fades. And, with our very large cyc wall, we didn’t want to have fillers on the floor.”
“We looked around at competitor products, but Selador was by far the best for the job,” said Peter Wikström. “It fulfilled the need for a smooth dimming curve, with no dip or flicker at the end. And the color-mixing on Selador is better than any other LED fixture.
“The theater cyc wall is a 15-by-25 meter [49 by 82 foot] curved wall. The fixtures couldn’t be too close to it; otherwise, the audience would be able to see the wall’s texture. However, we still needed to get an even light across the entire area.
“We ended up using 20 special double yokes and cross-shooting the fixtures’ beams so that they could all be focused from the same lighting truss.
“We calculated the amount of savings we could achieve from replacing the 48 1kW cyc lights with Selador,” Wilkström added. “When full on, Selador luminaires use a little over 11.5kW, while the cyc lights they replace use 48kW. Per year, this could be a savings of around €21,000 [$30,000 USD] or almost €360,000 [$510,000 USD] over the 50,000-hour lifetime of the Selador fixtures.”
Efficiencies included lower maintenance costs by trimming the need to replace lamps and filters.
