ZigBee is a low-cost, low-power, wireless mesh network standard targeted at wide development of long battery life devices in wireless control and monitoring applications. Zigbee devices have low latency, which further reduces average current. ZigBee chips are typically integrated with radios and with microcontrollers that have between 60-256 KB flash memory. ZigBee operates in the industrial, scientific and medical (ISM) radio bands: 2.4 GHz in most jurisdictions worldwide; 784 MHz in China, 868 MHz in Europe and 915 MHz in the USA and Australia. Data rates vary from 20 kbit/s (868 MHz band) to 250 kbit/s (2.4 GHz band).


Zigbee is A new trend for led lighting wireless control, low energy consuming, easy operation. We've developed our Clytze high bay with Zigbee module, along with Meanwell driver, we put it into a IP65 aluminum box which enables you to use our high bay both indoor and outdoor with Zigbee wireless control function. Besides Zigbee, there're manufacturers who like to use Bluetooth for similar control. But Bluetooth controlling area is narrow and it consumes more energy than Zigbee. For Zigbee system, if only use a gateway for signal, there can be a 200 meters controlling area. For further, using a wifi router to connect to the internet, you would be able to control, say from another city. The biggest advantage, as I said, is it's low energy consumption and easy operation, you almost don't have to pay more bills for it. Easy operation is you can either control your lights via APP on smart phone or using a remote controller. There's certain QR code for each lamp, scan it into the APP for control settings. Following is an overview of Zigbee that I extracted from Wikipedia.

ZigBee is one of the global standards of communication protocol formulated by the relevant task force under the IEEE 802.15 working group. The fourth in the series, WPAN Low Rate/ZigBee is the newest and provides specifications for devices that have low data rates, consume very low power and are thus characterized by long battery life. Other standards like Bluetooth and IrDA address high data rate applications such as voice, video and LAN communications.


The ZigBee network layer natively supports both star and tree networks, and generic Mesh networking. Every network must have one coordinator device, tasked with its creation, the control of its parameters and basic maintenance. Within star networks, the coordinator must be the central node. Both trees and meshes allow the use of ZigBee routers to extend communication at the network level.


ZigBee builds on the physical layer and media access control defined in IEEE standard 802.15.4 for low-rate WPANs. The specification includes four additional key components: network layer, application layer, ZigBee device objects (ZDOs) and manufacturer-defined application objects which allow for customization and favor total integration. ZDOs are responsible for a number of tasks, including keeping track of device roles, managing requests to join a network, as well as device discovery and security .
