- In a given circuit, the number and power rating of lamps are defined and cannot result in overload
- Only short circuit protection has to be provided
- J fuses or modular circuit breakers will be chosen for this purpose
- The lamps have very specific technical data, according to their construction type
- Incandescent lamps have a very high current on closing: more than 15 times nominal current they do not introduce a large phase displacement between current and voltage
- Fluorescent tubes are equipped with a ballast whose purpose is two-fold: contribute to ignition and limit current to nominal value once steady state is reached
- This ballast is a reactor that considerably lowers the power factor, it may or may not be compensated
