MadMax Question

I saw a post yesterday where someone said that their MadMax worked with one AAA and a dummy battery.If this is so, could the Mini M*# not be shortened to hold one cell and still work?

yep.

obviously not quite as bright though. would be neat!

Any idea how bright? Might be worth sacrificing an old Mini-mag body to make a key chain light.Wonder what it could be compared to(brightness) and how long it would last.

It would be about 75% as bright as using 2aa because mm is regulated.

i don't know how bright, but as shiftd said, it is regulated, and also has a lower dropof value than many regulated lights, giving you more brigthness from deader batts.

it would be worth if for the coolness factor alone i think. if not, then your only out about $8.

<font size="2" face="Verdana, Arial">Although the Madmax is regulating...it regulates voltage, not current. Led's like constant current, not voltage, since some led's vary so much in output with just a slight variation in voltage.... (that's why lots of people prefer the badboy, which is a constant current regulator).

However, the madmax is very efficient, and since it can run on lower voltages, it's a good candidate for this. Your light won't be as bright, but it should still be decent. Use a AA nimh battery (which has a very flat discharge curve), and you'll get more "predictable" performance on just one sell--you'll see more 'constant light output' compared to an alkaline.
