35-mm diameter spot LED modules
Zhaga Interface Specification Book 11 defines circular LED modules with a maximum diameter of 35 mm and a typical height of 3.5 mm.
Book 11 LED modules require a separate LED driver (electronic control gear).
There are three categories in Book 11, which are defined by the maximum diameter of the circular light-emitting surface (LES).
Book 11 modules are suitable for spot-lighting and other applications that benefit from a small, circular source.

News item (Sept 2015): Zhaga publishes Book 11 specification for small LED spotlight modules
Book 11 has several important features:
- It is part of a scaled family of LED modules (see below)
- It is the first Zhaga Book to describe an LED module only, rather than a complete LED light engine
- It is the first Zhaga Book to contain a reference to the LEDset specification for DMI
This Book must be read together with Zhaga Interface Specification Book 1.
