An AC-DC power supply receives input AC power and outputs DC power. The converter includes a high power factor bridge rectifier, a barrier circuit with resistor(s) and capacitor(s), and a step-down switching DC-DC converter to step-down a first DC voltage to a second, lower, DC voltage for output. Additionally, fault-protection is provided by redundancy in diodes on diode legs of a bridge rectifier and capacitor(s) of a filter circuit thereof, and a fault-protection circuit to sense current from a step-down switching DC-DC converter, a first voltage from the step-down switching DC-DC converter, and/or a second voltage at an output of the step-down switching DC-DC converter, and open the circuit on a fault.

A system provides for strobing or high conspicuity signaling with vehicle hazard and other lights depending upon inputs and parameters.

Embodiments of a live broadcast lighting system are disclosed. In one example embodiment, the live broadcast lighting system includes a light emitting apparatus, a control box being connected to the light emitting apparatus, and a device holder coupled to the control box.
