Another Homemade Flashlight

[joeqsmith]

I had made a video some time ago showing this Cree LED mounted to green heatsink, with no lens compared with some of our flashlights.  It's pretty bright.

Saved a couple of dead house LED bulbs from the trash along with a laptop battery pack that I gutted and sorted for good cells.   Taking apart the bulbs, the supplies had failed, but the LEDs were still fine.  So I mounted them to a heatsink.   

The reflector is the clear packing from a set of 4 D energizer cells.   I cut it in half and taped the two ends together.  The face cover is the clear plastic packing from some weed whacker parts.  Using a small boost switcher to drive it.   A 9V transistor battery will drive it.....

So here's the results of the trash picked flashlight held together with electrical tape....

Ambient is showing the camera pointed up into a tree with no lights.   Flashlights were ran left to right.   

FL1 is one of my first LED flashlights.  Amazed at how the LEDs have changed in such a short time.
