Zhaga Book 3 defines LED light engines (LLEs) that comprise a circular, non-socketable LED module with a separate LED driver (electronic control gear).
The circular LED modules in Book 3 have a typical diameter of 50 mm and a maximum height of 7.2 mm.
There are four LLE categories in Book 3, which are defined by the maximum diameter of the circular light-emitting surface (LES).
Book 3 LLEs are suitable for spot-lighting and other applications that benefit from a small, circular source.
