I plan on making one
like yours, but I might leave it on for long periods of time.

I have a few questions:

  • How
    many amps is it drawing when it is directly connected to the 8
    batteries? (I am not too sure but LEDs can draw more amps than the rated
    max amps for the flashlight if not regulated.
  • How
    hot (hot to the touch/warm/etc) does the heatsink get when it is running
    for about 3 minutes. (Is your fan running at full power too?) I am
    deciding if I should get a 50W or a 100W depending on the heat
  • About how long does the batteries last before it gets dim?

I am really excited to build one myself because of yours. I hope you can answer some of my questions.

None of the dealextreme links appear to be working.
