If the smart controller is installed with every lamp, then we have individual control. The system can collect information and control each lamp in the grid. However, if installed inside the feeder pillar, smart controllers enable segment-level lighting for a cluster of lamps. It’s more affordable and faster to deploy, but you lose some pretty important perks.
Both individual and segment controllers allow on/off control, either from a computer or a mobile phone, electrical grid feedback, and even completely autonomous lighting operation.
