The Black Diamond, a concert hall at the Royal Library in Copenhagen,
Denmark, has started using ETC Source Fours with enhanced definition
lens tube (EDLT) to provide stunning backdrops for the stage.
Purchased as part of an ongoing project to equip the venue with ETC
equipment, the venue found that they could mount the two new luminaires
in front of the backdrop and project a Rosco Fiery Sun gobo for a
bright, precise effect.
The Black Diamond technician Søren Jacobsen says: “I have worked with
sound for over 25 years, but it’s only in the past three years that I
have started working in lighting. Our local ETC dealer, Bico
Professionel, has been really useful in helping me select the products I
need and assisting with design and set up of the systems. We only needed
a couple ETC Source Fours equipped with a 36º EDLT to provide a stunning
effect. We projected the light from the front at a 10m distance: 45º
horizontal and 30º vertical. There was a little distortion in the
middle, but nothing significant. The producer and musicians were
The EDLT turns any Source Four into a superior image projector with
remarkably crisp, high contrast imaging with the most brightness
available (even more than the regular Source Four). EDLT provides the
greatest edge acuity (sharpness) available in a spotlight.
Hans Henrik Schmidt, sales consultant with Bico, adds: “After I showed
Søren the ETC EDLTs at PLASA, he was very eager to try the lenses
together with Rosco prismatic gobos. He realised that the combination
could give some fantastic effects, and I think that he has done a great
job with a few very effective tools.”
The set design is being used not only for concerts but also for
corporate events and private hires. The Black Diamond is the newest part
of is the national library of Denmark, which is the largest library in
the Nordic countries. Designed by schmidt/hammer/lassen architects of
Denmark, it was named for its outside cover of black marble and glass.
