Yeah a luxeon LED needs a regulator circuit, typically they run around 3-4 volts DC...
I'm a little bit concerned/curious with this last picture. In the picture, the flashlight is on, as is the charge-level indicator LED lights on the battery. What I'm curious about is, did you press the charge-level button just before you took the picture, to light up these LEDs right before you snapped the pics? Or, if not, are they on all the time on your battery when you use this light? What I'm concerned about is, if it is indeed the latter of these and they are always on with this flashlight modification, then that's not normal - the LEDs are supposed to go on for a second to show you the charge level, and then go off. If they stay on all the time with this mod, then the LED bulb could be causing some sort of harmful feedback to your battery.
Let us know, because that picture has spiked my curiousity. Thanks. Good pictures of the steps you took, also - it helps to have the photos here, for us to see the actual progress. Thanks.
It was just to show I had a full bat.
