Existing street lighting systems are obsolete
They operate on a fixed schedule: turning on at the same time and running at full power all night, even when the streets are empty. This is inefficient.
When the weather worsens, streetlights should turn on earlier. Late at night, when the streets are empty, they should operate at reduced power. Traditional systems are unable to do this—they cannot optimize energy use and do not report malfunctions. A burned-out lamp is only noticed when someone complains.
