LightWild overcame a series of challenges to produce a flashy, 380-foot-long curved fa?ade and background lighting for two lobbies at the new O2 World Arena. ![]()
Berlins O2 arena LED lighting project designer LightWild has just completed two software-controlled architectural projects on the newly opened, 17,000-seat, O2 World Arena in Berlin, Germany. The arena is located on 50 acres along the Spree River near the Berlin Wall East Side Gallery.
On the exterior, a massive LED installation stretches across the buildings curved glass facade and inside, two lobbies glisten with thousands of controlled fluorescent and LED fixtures behind frosted acrylic lenses. Visitors to the arena are greeted by the colorful moving graphics and video effects that are Driven across the installations on event nights. LightWild provided the engineering piece and the physical supplies. Installation was done by a German construction firm.
Randy Jones, LightWild's Director of Engineering, added that a key feature to the project's success was the company's "ability to work early on with the architects and engineers and achieve both the light output and the look — aesthetically — that was appealing to the owners. It was a rewarding challenge doing it long distance across the globe."
Using its LightWild Pixel as the LED light source, LightWild worked closely with the arenas architects — HOK Sport and JSK Architects — and owner Anschutz Entertainment Group to engineer a building mullion that houses the Pixels while blending seamlessly into the building exterior facade. In the lobbies LightWilds project engineering team and building architects designed a blue aluminum housing with openings for lenses that encased the Pixels and installed directly to the arena walls.

Curved facade LED fa?ade
The LED fa?ade is 380 feet (116 m) long by 40 feet (12 m) tall and is built on a 104-degree curve with an average radius of 213 feet (65 m). There are 117 vertical mullions spaced slightly more Than 3 feet (1 m) horizontally across the fa?ade. In all, there are 7020 LightWild Pixels installed in the vertical mullions on the fa?ade of the arena. With 40 LEDs/Pixel, 280,800 LEDs are in use on the fa ?ade.
"The curved fa?ade presented an optical challenge more than a physical challenge. Physically, each section of glass on the facade is flat but there is a slight angle (![]()
Lobby LEDs The main lobby walls and ceilings as well as the VIP lobby walls and ceilings provide a fun background using simple images and text. They feature 4494 fixtures (588 fluorescent and 3,906 LightWild LED Pixels) that are individually controlled from the arena control room through a LightWild-designed network transmitting DMX signals over Ethernet to the LED fixtures. The DALI protocol was also used to control the ceiling fluorescent fixtures.
The reasoning behind using LEDs
The owners of the arena weren't striving for energy efficiency as a main goal when building the facade. Instead, their client and naming rights partner, O2, a UK cellular company, liked LEDs because of their fast-changing characteristics and their flexibility. They could change the fa?ade at any moment to get passersby's attention.
Using a video display instead of LEDs was considered early on in the process. However, "the media feature was supposed to incorporate the entire fa?ade. A video system of that size would be astronomically expensive. Also, a conventional video display would block All visibility through the south fa?ade from inside the arena. Not only do our LEDs block 0% of the visibility, the light from our LEDs is imperceptible from inside the arena,†Jones said.
Contract details
LightWild worked locally with HOK, architects in Kansas City, who had seen LightWild's work on the south fa?ade of the Kansas City Marriott. HOK recognized that work and saw a place for it so contact contact LightWild and they began a series of engineering reviews With the Berlin team with trips to Berlin. Finalizing the plans took about a year. The contract was signed in early 2007 and the company delivered product to Berlin in January 2008.
"It was a very quick process, but we had to meet deadline of the arena's opening. We also had to fit within the owners' very stringent architectural needs concerning aesthetics, light output, and light pollution. We had to work with local authorities and Architects to make sure that all the regulations were adhered to."
One challenge was to "make sure all the LEDs, cables and controls would be concealed to the public but accessible within the architecture to the staff. We worked very closely with the fa?ade design team. On a detailed technical level, that was the Challenge part, but it worked out extremely well."

Opening night fireworks Results
When the arena opened on September 10th, the reaction was swift and positive.
"Everybody in the Anschulz Entertainment Group who had contracted us was ecstatic. At the opening ceremony, they couldn't have been happier," said Jones.
"One thing that was fun, during the opening events, was just walking around outside with the public, who were stopping and taking photos of the fa?ade. It was a kind of a rubber meets the road moment," Jones said." Yeah, people love this thing. It is so different. That was cool."
The arena will be used for concerts, sporting events, and other special events.
