JL-721NP series light controller products are intelligent rotary lock light controllers developed based on ZHAGA BOOK18 interface standard, It can be automatically dimmed by local ambient illuminance, or realized by NB-IOT remote real-time/strategy mode. The dimming mode supports DALI2.0 and supports GPS to automatically locate the geographic location of the device. The light controller is suitable for lighting scenes such as roads, Industry and mining，lawns, Parking lot，courtyards, and parks.

The page specifies DALI2.0 dimming and NB-IoT communication, with local ambient-light control and remote strategies. Confirm driver compatibility, the exact DALI implementation, socket wiring and management-platform configuration before ordering.
No. An interface or protocol description does not establish certification. Request the applicable certification record or conformity documentation for the exact controller and complete configuration before specifying a certified system.
The table lists customizable NB-IoT bands and a 12-24VDC supply. Confirm the supplied band configuration, SIM/service, coverage, power source and platform access. GPS positioning and network availability depend on deployment conditions.
