3x 1 Watt LED Flashlight

I made this flashlight using 3 1watt LEDs. They take 3.5volts, and around 300mA. I used a driver, and a good power source. Wont blow up like those stupid ones i see on Youtube. Also a good size heat sink was used. The parts used were:

- 1w LEDs

- 1-3 W Led Driver

-18650 battery with a booster to give the driver 12volts
