24 LIGHTING MAGAZINE | October/November 2014 October/November 2014 | LIGHTING MAGAZINE 25 Interestingly, and despite intensive efforts within the retrofit market to develop LED retrofit lamps, the current surge in LED uptake will eventually provide its own solution to this particular problem, according to LED Magazine: First, demand will drop as long-lasting LED lamps become predominant and don’t need to be replaced often. Second, purpose-built SSL luminaires will make much better use of LED sources and will become increasingly popular even in residential applications2. The growing popularity of LEDs is also driving the development of intelligent lighting applications that will further shape the retrofit market in years to come. Massive growth in multi-purpose LED technologies, such as smart light globes and associated applications that can be controlled via users’ smart phones or tablets, or li-fi enabled LEDs that can deliver internet connectivity via individual light fixtures, are on the cards, as are LED networks, which are also tantalisingly close to the mainstream. Imagine a lighting control system in which every light source can collect occupancy data via in-built sensors that allow it to communicate with its neighbours. According to Heather Clancy at Forbes.com: Each new LED fixture can, in essence, become the node on an intelligent controls network. Yes, these networks are really good at turning off the lights when people aren’t around or dimming them when it’s bright, saving electricity. But those sensors are also harvesting other useful data about temperature, occupancy and their surroundings that could have all sorts of other applications3. While they’re still some way away from being the norm, these smart solutions are already making lighting an integral part of the Internet of Things, a global network in which everyday objects are connected and share data. For clients, this vision of a smart future makes LEDs an attractive option for retrofit projects. The energy savings have already been proven, but the sheer volume of information that smart LEDs will be able to collect will make them an even more popular choice, particularly given the ease with which intelligent light sources can be inserted into existing plans where LEDs are already in use. Imagine, for example, being able to track customer movements through a retail space using sensors installed on your light fixtures – it’s market research at your fingertips. This information-rich future is currently just a twinkle on the horizon, but technology is moving fast. It took only a handful of years for LEDs to take centre stage in the retrofit scene – imagine where we might find ourselves in only a handful more.

The lighting concept is based on an integrated lighting system which enhances the new architectural finishes and form. The theatre is lit entirely with LED lighting (one of the first projects of its kind), creating the required lighting atmosphere whilst minimising maintenance requirements at the same time.
