if you really dont need max power, i would suggest a Palight Onestar with the optic removed.
though it is not aluminum, it has the "always on" feature, silent button, STARTS OUT DIM and ramps up to full intensity. easy to find in the dark, 9v bats and inexpensive--about $15. it is fully regulated.
with the optic removed, is has a great flood. i use mine almost nightly to get aroud the dark house without disturbing my sleeping wife.
i also take the pal with us when we travel. i put it on low setting, and leave it in the bathroom to illuminate those nightly bathroom visits.
another very nice possibility wold be an eternalight or inova 24/7.
