Common Problems with Low-Voltage Lights
Some common problems in low-voltage lighting include frequent burnouts, corrosion and voltage drop. These problems can be avoided by properly voltage regulation, lights protection as well as the system design.
Frequent burnouts occur in low-voltage lighting system because the lights are more sensitive to differences in voltage than standard 120-volt lights. Corrosion occurs in wiring connections and bulb terminals from humidity and water intrusion. Corrosion can add additional resistance to the lights and cause flickering, dimming or burnouts. Voltage drop is common in low-voltage lighting circuits which often causes dimming. This is due to undersized wiring or too many lights being on a single circuit.
