DIY High Power LED Rechargeable Flashlight

[sikeston34m]

I laid the LED on an 3" aluminum disk and ran it for about a minute straight. This kept the LED much cooler and only warmed the disk up lukewarm.

If the LED is only being fed it's rated voltage AND heat is controlled, why is a driver needed at all?

I realize there are dimmer driver boards that allow modes of operation.

25%, 50%, 100%, flasher and even SOS signals.

I just want 100% or nothing. Simple Enough.
