Mag Tail cap regulator

I was thinking that there was possibly enough space in a Maglite tail cap under the spring to insert a voltage/current regulator. It seems like it is impossible to get the most out the LEDs (and batteries) without one. My 19 LED degrades fairly quickly, and while you could argue that they are more efficient when underpowered, that means little when you just need raw power. When I crammed 4 nicad c cells into the 3 D body the 19 LED light was spectacular, but quickly got too hot. I could either try better heatsinking methods or adjust the voltage to keep it just on this side of safety. Is this idea even feasable? Can the circuit use the body as a shared ground?

Hi Chet!

There is a little mechanical problem:

You will have to hook a voltage regulator to 3 points: Input voltage +
Output voltage +
Common Ground -

In a Maglite this is:

Input volt + : The head of the innermost battery

Output voltage + : The poit where the innermost battery poits usually to (The contagct between these two has to be broken up..)

Common Ground: negative pole of the outermost battery and the whole case.


So you cant build a voltage regulator only into the tailcap...

But there is plenty of space in the head of a Maglite, with some fantasy you can put it here

Bye!
