The lighthing capacitor series LCP (plastic case) and LCM (metal case) are designed to improve the power factor of discharge lamps:
- Sodium lamps.
- Halogen and metal vapour lamps.
- High pressure mercury vapour lamps.
- Low pressure mercury vapour lamps.
- Fluorescent lamps.
These lamps require magnetic ballasts and transformers for ignition and for Current limitation during discharge.
The improvement of the power factor is achieved by the installation of a capacitor of adequate capacitance into the light fitting. This can be done in the classic series connection or parallel connection.
Failure to use a capacitor of adequate capacitance could result in damage to the capacitor or the light fitting due to the high temperature during service and the transient over-voltage caused by the switching on and off operation.
