EDIT: 9-LED light, not 7 
As part of a shipment some time back from one of our great suppliers, I got this cheap, 3xAAA, 9 LED light. The light was unreliable, had a reverse clickie, and although just plain cheap, the 9 LED's gave a nice, pleasant, almost white beam - much, much better than the tipicall "angry-blue" that most 5mm LED's have (my guess it came with 20 or 25K White LED's):
Playing with the module I found that the LED "module" fit perfectly inside the head of a "C" series SF (6P in this example). So using an POP module (still in UI mode 1), I played with the LED module and found that it was a great match for a very long running light that would take the 4.2 LiIon cells (17650, PILA 168S, and if bored-out the mighty 18650 cell!). So I decided to build myself a new module
I used part of the tailcap of an old, dried-out, black marker as host for the POP module, and an old spring from a 4xAA battery pack for the positive battery contact. The negative connection is made by the outer ring of the LED module contacting the inner part of the metal 6P host near the neck (so this can't work on the G2 type lights).
The results are awesome!. With a fresh PILA 168S I recorded 307mA on max, which is about 34mA to each LED - a little high, but not too much. I now have an adjustable, super long running light for home and close-range use, built (except for the POP module) on free stuff I had around me
Note the bezel can't quite close completely, but still water tight by the o-ring:
These "modern" electronics can turn almost any boring LED light into something a lot more practical, and fun
