LED modules for spotlighting
Zhaga Book 10 defines a family of circular LED modules that have a small circular light-emitting surface (LES). Book 10 LED modules can be used with luminaire optics such as lenses and reflectors, and are typically used in spot-lighting applications.
Book 10 contains simplified and harmonized specifications for the LED modules that were previously described in older Zhaga specifications:
- Book 3 (50-mm diameter LED modules)
- Book 11 (35-mm diameter LED modules)
Book 10 modules can be standalone LED modules, or they can be constructed by combining a COB LED array (defined in Book 12) with an array holder.

The Zhaga Consortium will review and update these specifications from time to time. To ensure you are aware of any updates to the Zhaga specifications, please subscribe to the Zhaga newsletter.
There are two LED module categories with different outer diameters.
- D35 = 35mm diameter (formerly Book 11)
- D50 = 50mm diameter (formerly Book 3)
A range of light-emittng surface (LES) diameters is allowed. Details are given in the Tables below.
The LED modules operate with a separate LED driver (electronic control gear). They are typically fixed to a heat sink using screws. The light output is essentially Lambertian to enable the luminaire optics to shape the application’s desired light distribution from a defined input.
