Do You Need to Change the Transformer ... - Service Seeking Current; Observe the current requirements on the transformer usually specified in amps or milliamps. It can be given in values such as 350 mA, 500 mA, 700 mA, 1050mA or in a range like 0 mA to 500 mA. Match the amp rating to the one required for your LEDs. You might want to run your LED applications at a lower current to improve durability.
