simple led driver using light sensor to turn on led's in bathroom. Led's are turning on when main lights are turning on. Light resistor is set to dark environment.
Led's are working at 3V, this way I don't need use resistor i parallel with led's, Transistor Beta is 300.
If You use mosfet, You can safe extra miliamps.
