can i pilot a powerful led

hi I would like to connect to a distance sensor a powerful enough LED to illuminate a room. the sensor would function as a remote switch with dimmer. I managed to do it with a small LED (managing the power from the appropriate pins) how can I do with a much more powerful LED that is not enough for the 5 volt of the Arduino ?

Hi,
See THIS PAGE

Scroll down to "DC SWITCHING" and you will see how to use a power FET to dim a larger lamp or LED.

thank you so much!!!
