Zhaga is an industry consortium publishing 'books' that standardise LED modules, drivers, sockets, and sensors. Book 18 = outdoor LED engine. Book 20 = NEMA 7-pin equivalent for street lights. Book 24 = sensor add-on socket. Buying Zhaga-compliant fixtures means you can swap LED engines or sensors years later without changing the housing.
Four ideas to carry into the next specification conversation you have.
Defines socket geometry, electrical interface, thermal spec. Open consortium, not single vendor.
Replaceable LED+driver module for streetlights, floodlights. Upgrade efficacy without re-poling.
DALI-2 + DALI bus + auxiliary power. Used for street smart-city controllers (Saudi smart cities mandate it).
Mount IR / radar / camera modules to existing luminaire via standardised socket. Add features later.
Which Zhaga book covers which standardisation.
| Book | Scope | Use |
|---|---|---|
| Book 3 | Square indoor LED engine | Office downlights |
| Book 7 | Round LED engine + driver | Spots |
| Book 11 | Linear LED engine | Office linears |
| Book 18 | Outdoor LED+driver module | Streetlights |
| Book 20 | Smart-city receptacle | DALI-2 controllers |
| Book 24 | Sensor add-on | Smart sensors |
Five reasons Saudi smart-city LED projects mandate Zhaga.
LED efficacy improved 50% from 2015 to 2025. Zhaga lets cities swap engines on existing poles, saving the cost of pole replacement.
NEOM and Riyadh smart-light projects require sensor sockets. Book 24 means cameras, environmental sensors, 5G small-cells can be added later.
Zhaga compliance means cities aren't locked to one LED supplier. Saudi muni RFPs increasingly require Zhaga as a precondition for bid.
Cities don't have to throw away the whole fixture when a driver fails. Replace just the Zhaga module, drops 5-year TCO significantly.
Zhaga doesn't replace electrical safety standards. It complements them, the LED module is still tested per EN 60598, but the socket is universal.
Our smart-city outdoor range ships with Zhaga Book 18 LED engines + Book 20 NEMA-equivalent controllers + Book 24 sensor sockets. Engineered for Riyadh / NEOM 25-year roadmaps.
