Book 17:

Spotlight LED light engines with integrated driver

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.

The maximum LLE diameter is 80 mm, and the maximum height is 15 mm.

The mounting-hole spacing is 35 mm, which is the same as for Book 3 LED modules.

A range of LES categories is possible, based on the LES diameter, and these are the same as for Book 3.

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


Book 17 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.
