Zhaga Book 24: Standardized LED Light Engines
Zhaga Book 24 standardizes the LED light engine - the module plus its connector - so a luminaire maker can swap engines between suppliers without redesigning the fixture.
What It Standardizes
Book 24 defines the mechanical, thermal and electrical interface of an LED light engine (the COB or array plus its connector). The luminaire housing stays fixed; the engine is interchangeable.
Connector and D4i
The engine connector carries power and, on D4i variants, digital addressing. A Book 24 D4i engine reports its flux and thermal data to the driver automatically.
Why Specifiers Care
- Second-source: buy the same form factor from more than one supplier.
- Serviceability: replace an engine, not the whole luminaire.
- Future-proof: move to a higher-efficacy engine in the same cutout.
Is Book 24 the same as Book 18?
No. Book 18 is the outdoor dimming socket; Book 24 is the LED light-engine interface. They solve different joints in the luminaire.
Do I need D4i to use Book 24?
No. Book 24 covers the mechanical/electrical interface; D4i is an optional digital layer on top.
