Overview of Zhaga Books
Zhaga is creating a series of specifications, known as Books. Each Book defines one or more components of an LED luminaire. Such components include LED light engines, LED modules, LED drivers, LED arrays, holders, and connectivity fit systems.

Books define the mechanical, photometric, electrical, thermal, and control interfaces of the component to its environment. Defining the components in this way makes them interchangeable in the sense that it is easy to replace one component with another (either at the manufacturing stage, or in the field), even if they have been made by different manufacturers.
Books by Application
The applications shown below are suggestions only. Zhaga Books do not restrict the application for which a component can be used.

Books by family
Books 3, 10 and 11 comprise a family of circular LED modules with a range of sizes. These are suitable for spotlighting and related applications.
The LED modules in Books 3, 10 and 11 operate with a separate LED driver. For each Book and module size there is a range of categories based on the diameter of the light-emittng surface (LES).
Spot family of modules - comparison of sizes and LES categories
Book 11 - 35 mm diameter modules
Book 3 - 50 mm diameter modules
Book 17 defines LED light engines (LLEs) with an integrated driver and a circular light-emitting surface (LES). These are suitable for spot-lighting applications such as compact indoor luminaires.
Book 7 specifies a family of linear and square LED modules, with a wide range of dimensions.
The modules operate with a separate LED driver and are intended primarily for indoor lighting applications.
Book 9 specifies a set of LED modules with a ring-shaped light-emitting surface (LES).
The small, mid-power LED modules operate with a separate LED driver, and have diameters of 12 mm or 25 mm for the ring-shaped LES.
Book 12 defines a family of rectangular and square LED modules with a circular light-emitting surface (LES). These modules require a separate LED driver, and can be used either with or without holders, depending on the luminaire type and application.
Most Book 12 modules will use chip-on-board (COB) technology for the light-emitting section.
Book 13 defines the interface specifications of LED drivers (also known as electronic control gear, or ECG) that can be used in combination with different LED modules.
Book 16 defines planar, circular LED light engines (LLEs) with an integrated driver. Such LLEs could be used in flat, circular luminaires with a homogeneous, low-glare surface.
Book 18 will define a standardized interface between a sensor and communication module, located on the exterior of an outdoor LED luminaire, and the LED driver inside the luminaire.
Book 4 defines the interfaces of high-intensity LED light engines (LLEs) comprising a rectangular, non-socketable LED module with a separate LED driver (electronic control gear).
For applications that need a high-intensity light source, such as outdoor and industrial lighting.
Book 15 defines LED modules that are designed to be used in conjunction with lens arrays, for outdoor lighting applications.
Book 14 defines a linear LED light engine (LLE) with a cap/holder system that enables tool-less replacement.
Several Zhaga specifications describe circular, socketable LED light engines and modules. These light sources are designed to fit into a socket or holder, which in turn is typically fixed into a luminaire.
A Book 2 LLE has a round drum shape with maximum dimensions of 70.2 mm diameter and 45 mm height. It has a circular light-emitting surface with a typical diameter of 59 mm, and a PHJ65d type base.
A Book 8 LLE has maximum dimensions of 95 mm diameter and 45 mm height. The circular LES with a diameter in the range of 59 mm to 71 mm, and a PHJ85d base.
Book 6 defines a socketable, circular LLE with nominal dimensions of 90 mm diameter and 42 mm height. The LLE has a GH76p base.
Book 5 defines a socketable, circular LED module with a separate LED driver. The circular LED modules in Book 5 have maximum dimensions of 70 mm diameter and 21 mm height.
