104 TECHNOLOGY / BENCHTEST rently are:
1) LED light engine with easy-fit socket and integrated control gear: This specification describes the interfaces for a downlight engine. The specifications are currently available for review by members only but will be made available for public download later in 2011.
2) Spotlight engine with separate control gear: The second light engine is the speci- fication for the interfaces of a spotlight engine.
Further Zharga light engine specifications will be developed for: • A streetlight engine (non-socketable with separate control gear) • A spotlight engine (socketable with sepa- rate control gear) • A compact socketable light engine with integrated control gear • A circular, 85mm, downlight engine for high lumen output (socketable with inte- grated control gear) • A rectangular light engine for indoor use, suitable for tiling.
In addition to the interface specification of light engines, the Zharga consortium is also developing supporting specifications that will be reused for multiple light engine interfaces. The mechanical dimensions and fixation points of LED control gear will also

be considered in the future. It is important to understand that the performance of such LED modules will be defined in the current way through perfor- mance metrics and company datasheets as shown in Figure 4 so our testing provides a first glimpse of what is to come for LED modules.
