Παράθεση:
In addition to matching the line voltage, a ballast must exactly match the type and number of lamps used. Each ballast is marked with the list of the sizes and number of lamps that the ballast can operate, along with a diagram showing how the lamps must be connected to the ballast. Connecting lamps larger than what the ballast supports may cause the lamps to malfunction or operate dimly, while lamps smaller than what the ballast allows will be able to draw too much current and can overheat. Either incorrect situation can also damage the ballast or cause a fire hazard.
