Book 16:

Planar, circular LED light engines with integrated driver

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.

The first Edition of Book 16 will include a range of LLE diameters:

  • 130 mm
  • 180 mm
  • 250 mm
  • 350 mm
  • 500 mm

The specification will allow components to be placed on both sides of the LLE, if required. The possibility of adding smaller diameters will be discussed in future.

Due to the integrated driver, these LLEs operate using AC mains voltage.


Book 16 is currently at the draft stage. Once it has been approved for use by Zhaga members, it will then be published in due course.

Companies are invited to participate in the development of this Zhaga specification. Please contact Zhaga’s Secretary General for more information.
