LED and lights driver units
More sophisticated ballasts can be run as a constant current regulator in analog (linear) or digital (switch-mode) technology. The benefits of digital technology come in particular to fruition when used for high-power LEDs with power from 1 watt.

Network devices form the bridge from 230 Vac mains power supply (socket) to an easier to handle low voltage of 24 Vdc. These are constant voltage devices. Pure LED's can not be operated without limiting the current.
