Zhaga is an industry-wide cooperation between companies aimed at enabling the interchangeability of LED light sources made by different manufacturers.

Interchangeability is achieved by defining interfaces for a variety of application-specific light engines.

Zhaga specifications cover the physical dimensions, as well as the photometric, electrical and thermal behavior of LED light engines.

Zhaga was established to benefit consumers and professional buyers of light engines and luminaires in the expectation that interchangeability will prevent market fragmentation into incompatible products.

Zhaga specifications increase confidence in specifying and purchasing LED products that are easily replaceable and commercially available, while continuously enjoying the performance upgrades that LED technology brings. This will help speed up innovation and improve competition in the application of LED lighting in general.

An LED light engine is the combination of an LED module and the associated control gear.

Zhaga treats LED light engines as a black box, with defined interfaces that do not depend on the type of LED technology used inside the light engine.
