Do you still have, or know anything about, the original flashlight this came from? That would tell you what voltage the LED needs to operate, from which math :-) will get you the current (P = VI).

Without the flashlight, you're going to have to try to find a part number stamped on the LED itself. There are 5W LEDs available for a variety of voltages, from 4V all the way up to 240V.
