Socketable linear LED light engines
March 2017: Book 14 Edition 1.1 is now published. Edition 1.1 includes both LED modules (requiring a separate driver) and LED light engines (integrated driver). More details will be available soon.
Book 14 defines a family of ultra-slim, linear LED light engines (LLEs) that are suitable for low-profile linear lighting.
By definition, the LLEs contain an integrated driver.
The LLEs have a cap/holder system that enables tool-less replacement. One end of the LLE has a contact cap, which fits into the corresponding contact holder in the luminaire, while the other end has a support cap and support holder.
The intended application is in free air (i.e. the holders are not surrounded by a luminaire body), or in a luminaire that does not introduce a significant temperature increase.
For a short overview of Book 14, watch the video below or download the presentation (PDF file).
Book 14 Edition 1.1 is Approved, and the full specification is available for use by Zhaga members only.

The specification will be published in mid 2017.
The Zhaga Consortium will review and update this specification from time to time. To ensure you are aware of any updates to the Zhaga specifications, please subscribe to the Zhaga newsletter.
This Book must be read together with Zhaga Interface Specification Book 1.
There are three LLE categories in Book 14, as shown in the Table. Zhaga defines the maximum outline of the LLE, the position of the support cap and contact cap in the LLE, and the position of the support holder and contact holder in the luminaire.
|Category||Max. LLE length|
|L60W5||565 mm (2 ft)|
|L120W5||1166 mm (4 ft)|
|L150W5||1466 mm (5 ft)|
The LLEs have a maximum height of 35 mm and a maximum width of 50 mm, although much flatter and narrower LLEs are possible.
Like most Zhaga specifications, Book 14 does not restrict features such as the position, type and performance of the LEDs used inside the LLE. However, manufacturers will need to measure and report a specified set of data for each LLE product.
Zhaga members can certify products according to this Book, using various Authorized Test Labs.
Products that are certified according to each Book are listed in the Certified Products database.
