Conventional low voltage transformers are also known as magnetic core which can be very huge and heavy, it consist of an iron core and two sets of wires An electronic low voltage transformer, on the other hand, as well includes an electronic device, known as an inverter, which let the size of the low voltage transformer to be considerably smaller. An inverter and a small transformer structure the major components of what we in general known as electronic low voltage transformer.

Electronic low voltage transformers are extremely light and smaller in size when compared to magnetic low voltage transformers, in the majority cases small sufficient that fixture manufacturers can regularly fit in them within their light fixture relatively than parting the purchaser to find a hiding place. Yet when not included in the lighting fixture an electronic low voltage transformer is extremely trouble-free to set up in a small hidden place.
