An electronic transformer is used to reduce mains voltage to a suitable voltage for halogen light bulbs (Not to be confused with LED Drivers). When selecting a transformer it is important to ensure the max wattage is not exceeded by the total wattage consumed by the light bulbs.
Please Note: It is not recommended to "max" out transformers.
IE 5no. lamps x 10 watts each = 50 watts therefore a 60 watt (60VA) transformer would be acceptable, however if you had 6 lamps a 60 watt transformer would be "maxed" out. In this case we would then recommend a 105 watt (105VA) model.
The original type of ballast, the electromagnetic ballast was introduced with the first iteration of fluorescent lamps.
