The beam produced by a Luxeon III in a parabolic reflector is better than
that of the inexpensive incandescent bulb. The "beam" is quite adjustable
by relocating the LED slightly.
I have built several conversions of old flashlights to accept LEDs. They
all work. But, the light I carry in my pocket is a Coast LEDLenser V^2.
Nothing I've yet built is as nice as this little Ledlenser.

[maglite mods]

I have seen conversions for the mini mag here in UK.
One question, does the variable focussing still work?

Incandescent bulbs produce (pretty much) isotropic radiation - the
same light in every direction. Maglite reflectors are designed for
this radiation pattern. Forward-emitting LEDs, which project their
beam in a fairly narrow angle anyway, mostly miss the reflector (how
much varies with the reflector and LED beam angle), so focussing
doesn't really work. I've seen mods with two back-to-back
side-emitting LEDs, which would presumably retain some focussing
ability, albeit with a slightly different pattern.

I'll stick with my Surefire E1e I think, but I'm going to get the LED
head when the next bulb goes. If you think maglite bulbs are expensive
then check out the Surefire ones! It's a silly flashlight really - if
I lived in outside the city I'd have something more sensible, but it's
so pretty and so bright I love it.

Flashlight freaks hang out he http://www.candlepowerforums.com/ and
there is loads of info available by searching the forums.
