im no led guru, but led's seem to be either
voltage limited
or amperage limited to control intensity
the key is finding which one

of course u can also find the circuit board. look up the resistor to figure out some voltage, ohm, wattage math and figure out what ur led's are using

if its a 3w led though, i wouldn't drive it much harder without adding heat dissipation or the wont last very long
