What Are Zhaga and NEMA Lighting Controllers?
Both Zhaga and NEMA controllers are used to connect and control outdoor lighting, such as streetlights, parking lot lights, and smart building lighting. They allow lights to be monitored, dimmed, or turned on and off automatically based on data like daylight levels or motion detection.
However, they differ mainly in design standards and connectivity:
NEMA controllers follow the ANSI C136.41 standard, which uses a 7-pin connector typically mounted on top of luminaires. They’re widely used in North America and ideal for large outdoor lighting systems.
Zhaga controllers, developed under the Zhaga Consortium, use a smaller, low-profile connector (usually a 4-pin design). They support modern smart city applications and are often used in Europe and Asia for compact LED fixtures.
