After many disapointments with flashlights I have finally found my "perfect" light. The CMG Infinity is a single LED powered by one AA battery. Rated 40 hrs burn time (double that with a lithium battery) and 150,000 hrs on the bulb!!!! It weighs .9 oz and you can wear it around your neck with the glow in the dark lanyard that is supplied. The bulbs come red, blue, green, amber and white.
Lightweight, longlasting, and just enough illumination for those campsite chores. This one's a keeper!
