With this device, you can adjust the brightness of a powerful halogen lamp at a voltage of 12 volts.The device uses pulse-width modulation, so the key-field transistor will not get very hot, it does not need a heat sink.
50 Watt lamp,field effect transistor p45n02ld.This is a logic-level transistor, which means that it can work well at a voltage of 5 volts.Timer 555 generates a rectangular signal that can be adjusted by resistor R2, thereby changing the brightness of the lamp.With the capacitance of the capacitor C1 470 pF, the overlap frequency of the generator will be about 19.8-26kHz
As a load, you can use a powerful LED or another load that can be adjusted in power.
