LIghthouse is right.... HID puts the others to shame for the most part... or at least when talking about the common mans light..... as its only recently becoming common itself. You will find very long runtimes for the amount of light you get with the battery size considered.... they are pretty efficient.
LED's have taken a large step forward too, but your wanting the brightest for the money....
The
Amondo N30 you may like better.. a little more money, "148.00" but an HID with NIMH instead of lead acid and 35Watts HID and very compact.
There are a few cheap ones that really cut the mustard pricewise, but you have a giant reflector to deal with.
Getting lots of lumens from a smaller reflector takes some engineering and the N30 does an excellent job for the money.... otherwise you can carry around a
9 inch reflector if you prefer!
I"m sure it makes you feel like a man to carry around 9 inches... just not real practical.... remember... size doesn't matter!
Its not real often you get to really use the whole 9 inches anyway.
