Led to shoot the light, the 12 v transformer and transformer can general ordinary lamp?
Can't, because leds points of positive and negative polarity (dc), and ordinary lamp general both (ac). If money does not can be connected to use after rectifying, pay attention to the polarity.
Transformer are interchangeable, but LED is a dc power supply, if the pressure after the bridge rectifier, more than 12 v, also need to consider the LED string and method and current limiting resistor.
Ordinary lamp useful pure transformer circuit, there is also a high frequency of the oscillation circuit, output are communication, if the switch power supply can be used directly
