3W Homemade Flash Light

At some times, I just need a bright flash light, that doesn't costs too much.

Yup, I'm using discarded Li-Ion batteries. 

No lens attached yet.

Front view. Note the heatsink.

Switching mechanism is just a simple wire header.

Close-up.

Operating.

3W is bright enough for now.
