I need a light that's at least strong enough to leave the tent to pee safely in the middle of night and preferably strong enough to pack up camp and start hiking just before dawn. I don't need multiple intensities, a red light, strobe, etc. Just bright, strong & lightweight with a reliable on/off switch that'll last at least 1000 miles. Adjustable angle and using AAA batteries for power would be nice but are not essential.
