| NEMA (ANSI C136.41) | Zhaga Book 18 | |
|---|---|---|
| Origin | North America, ANSI C136 | Zhaga Consortium, international |
| Pins | 3-pin (C136.10), 5-pin, or 7-pin twist-lock | 4-pin, small and low |
| Mains on socket | Yes. The node switches mains. | No. Only 24 V and DALI data. |
| Dimming | 0–10 V or DALI on pins 4 and 5 | DALI (D4i) |
| Positions | One, on top | Two: top (radio) and bottom (sensor) |
| Node cost | Higher | Lower |
Usual choice in Europe: Europe: Zhaga Book 18 for new luminaires. NEMA on some older or imported ranges. Middle East: NEMA 7-pin is very common, because many authority specifications follow North American practice. Zhaga is growing on new European luminaire ranges. South Asia: Many installed luminaires have no socket. New tenders increasingly ask for NEMA or Zhaga. Specify one to avoid luminaire replacement when you add nodes. USA: NEMA 7-pin (ANSI C136.41) on almost all new roadway luminaires. Zhaga is rare.
Zhaga-D4i certification
A joint programme of the Zhaga Consortium and the DALI Alliance. It certifies that luminaire, driver, and node work together. Ask for this logo in tenders that use Zhaga.
Note
With Zhaga Book 18, the node does not switch mains. The driver stays powered and turns off by DALI command. Check the standby power on the datasheet.
