The Lumination range is based on a high efficiency LED panel with the first products being recessed panels designed for use in general commercial applications including offices, retail and circulation areas. Luminaires for the architectural market will be launched in 2012.


would be based on the amount of lit ceiling surface as there is no upward light from the panels themselves. Available in three colour temperatures the panels deliver around 3700 lumens with a consumption of 50 watts giving a very ac- ceptable 74 lumens per watt. The projected life to 70% of initial lumens is the industry standard 50,000 hours and the panels have a five year warranty. The back of the Lumination panel is made of pressed aluminium and, when running in free air, is very cool. When recessed into a shallow ceiling void with limited air movement, the luminaire is likely to run somewhat hotter. The maximum operating ambient is 40°C which should be sufficient given the low heat sink temperature. The LED driver from Lightech, now part of GE, has a thermal cutout in case the internal ambient rises above a safe level. DALI and 1–10V dimming is standard and a plug-in emergency lighting LED module is under- stood to be in development. The keys to success with a LED panel


luminaire of this type for general com- mercial lighting are performance and cost. There is a great deal of competition from many manufacturers in this product sec- tor. GE has prepared projections showing energy savings and payback times for the Lumination panel in schemes to replace high quality T5 luminaires. These show savings ranging from 12% when luminaires are replaced on a one-to-one basis rising to 35% when the whole scheme is redesigned around the distribution and output from the GE panel. Payback time ranges from two years for a retrofit project rising to seven or eight years in a new-build scheme. Production of the first set of panels is in Taiwan but once sales volumes rise, produc- tion will move closer to the relevant sales market: Hungary for the European market and Mexico for the North American market. The initial Lumination range took fourteen months to come to fruition with input from two external design companies both located in Europe. The next product release will be the


suspended panels which should have visual appeal for the architectural market. The samples of these suspended luminaires shown at Lightfair benefit from the innova- tive and attractive design feature that the micro prismatic panel becomes transparent when the LEDs are not lit. The company says that there has been con- siderable interest in the vertical batwing panel from a number of retail operators for use as an efficient asymmetric wall washer to illuminate both sides of an aisle from a central luminaire. Although the first release of the Lumination range is not the most exciting luminaire from a visual or illuminating standpoint, it is well-engineered and the Rambus micro prismatic controller is very effective. A variety of project sales have already been made in diverse parts of the world and it seems very likely that the Lumination range will become a very successful part of the rejuvenated GE luminaire offer. www.gelighting.com
