A number of Zhaga-member companies already offer products that are certified according to Book 8 - these can be found in the Certified Products database.
The LED light engine (LLE) has a PHJ85d-type base with a diameter of 85 mm. It can be locked into a holder inside a luminaire by means of a twisting motion. Mechanical fit keying is present to ensure that the luminaire provides the correct mains voltage.
The light output is essentially lambertian, which enables the luminaire optics to shape the light distribution to the needs of the application.
The light engine is intended primarily (but not exclusively) for use in LED luminaires for downlighting applications.
This Book must be read together with Zhaga Interface Specification Book 1.
