Simple 10W High Power LED Driver Circuit

This is my project for handmade flashlight when using 10W High Power LED voltage 12V DC. Indeed, by using this LED light produced is very bright. However, to use this LED requires a power of 10W and 12V stabilized voltage, so that LEDs are more durable long lasting without reducing the productivity of the light produced High Power LED's.



So it takes a LED driver circuit, precisely to control
