This Video Light Is Awesome - Vivitar Creator Series Studio Light Pocket with 126 LEDs
Here's a quick unboxing, review and video samples featuring the Vivitar Creator Series Studio Light Pocket. It's powered by an internal rechargable battery, and has 126 multicolored LEDs that allow for some crazy flexible tonal options. It even has a special effects mode. I bought mine at Walmart for around $40. It's the same size as a cell phone and seems to be VERY well built.
