Subject: Front light bulbs - LED vs. halogen vs. krypton vs. xenon...

I'm trying to determine the relative suitability of LED, Xenon,
halogen and krypton bulbs for use in cycle headlights for use on unlit
roads. I hear people say that LEDs are the most efficient, but I also
hear people say that it's difficult to focus them into a long enough
beam for use on dark roads. I hear people say that Halogen lamps are
more suitable because they give longer beams, but are not as
efficient. I hear people say that krypton bulbs are better, and I hear
people say that xenon bulbs are better still. Anyone agree?

What I want, personally,  is a front light that is *inexpensive* and
will give a long and sufficiently wide, bright beam for 2-3 hours on 2
or 4 rechargeable NimH 'AA' batteries - and isn't likely to blow its
bulbs. Is that feasable? Which of the above bulb types is most likely
to be in such a lamp?

Thanks...

Jim D
