Zoomlite - Single AA Optic Torch

The Hitech Illumination Zoomlite is a pocket-sized multi-mode focus-able optic torch that outputs a massive 130 lumens on a single AA battery.

It features a sturdy pocket clip, low, high and strobe modes and is compatible with a lithium 14500 battery for double the brightness. Best of all it retails for only $30, including shipping and AA battery.

This is a budget light, but the focus-able beam makes this worth having.
