The Zhaga Consortium has published its Book 7 and 8 specifications for LED light engines (LLEs), essentially placing the standards into the public domain for usage by any company. The new specifications, for modules focused on linear/square fixtures and downlights respectively, join Books 1, 2, and 3 that Zhaga previously made available for public use. Modular solid-state lighting (SSL) technology in general, and Zhaga-based modules in particular, are meant to accelerate product development and in the case of Zhaga allow lighting manufacturers to choose from compatible LLEs offered by multiple vendors. There are now Zhaga specifications, that the consortium calls books, to serve in a variety of indoor and outdoor fixtures types.
