As part of its preparations to host the London 2012 Olympic Games, the ExCeL London International Exhibition & Convention Centre expanded its efforts to convert the facility to greener, more energy-efficient LED lighting, replacing 35 existing 400W high-pressure sodium (HPS) fixtures with Dialight’s new 150W 14,000-lumen High Bay LEDs to better illuminate the north side exterior of the massive structure in the loading dock and traffic marshaling areas.
The latest change-out project built upon the 2010 retrofit of 194 400W high-pressure sodium units with 150W Dialight High Bays throughout the building’s one-half-mile-long Central Boulevard area. That conversion reduced energy consumption by 70 percent in the main thoroughfare and enabled the 100,000-square-meter ExCeL London, one of the greenest and most energy-efficient exhibition centers of its kind in the world, to double the on-floor illumination (from 100 to 220 lux) and achieve three times the energy efficacy (4.2 W/m2 compared to 12.32 W/m2 with the previous HPS units).
The new exterior installation enhances illumination and visual clarity for improved traffic management and security in the area where event-related equipment staging, loading, and unloading takes place, as well as at the entrance/exit to the facility’s massive underground parking areas. The previous HPS fixtures were plagued by extended warm-up periods and were on a manual switch, which meant they were often accidentally left on when not needed because personnel simply forgot to shut them off, wasting valuable energy and money.
Elite Renewables installed each new Dialight fixture with a photocell for automatic dusk-to-dawn operation and the instant- on capability adds safety and security. In the event of a power failure, the Dialight LEDs will immediately restrike at full output the second the backup generator kicks on, virtually eliminating this safety and security risk at the high-profile event center. The new units are also maintenance free, backed by Dialight’s 5-year full-performance warranty.
ExCeL London will play host to 7 Olympic and 6 Paralympic events when the Games of the Olympiad kick off July 27, including the boxing, wrestling, judo, tae kwon do, table tennis, boccia, weight lifting and power lifting, fencing, wheelchair fencing, and sitting volleyball competitions.
